What does it do?Breaks down the ABAP source code in the source code table itab1 into tokens according to the rules of the ABAP scanner. The tokens are written – one per row – to the token table itab2. The source code to be broken down need not necessarily be contained in an internal table. It can be specified in any character-like field. In particular, fields of the type STRING can be used. However, this variant only makes sense if the program to be broken down does not contain any comments. When an internal table is specified, itab1 must be a standard table without secondary keys.

The token table itab2 must be a standard table without secondary keys and have the structure STOKES. If the addition WITH ANALYSIS is specified, the token table must have the extended structure STOKESX.
(For reasons of downward compatibility, STOKEN and STOKEX can still be used. The main difference is that in the new structures the character string which makes up the token is typed with reference to the data type string. With the structures STOKEN and STOKEX, a C field of length 30 and an OVERFLOW area are used instead.)

Normally, comments are filtered out and subordinate source code units ( include programs, called macros) are ignored. These semantics can be modified by using the additions WITH COMMENTS and WITH ANALYSIS.

In addition to classifying the source code by token, the scanner organizes the tokens themselves into statements (using the colon-comma logic to form chained statements) and the statement table itab3 contains a statement description on each row. Here, a three-part chained statement 'a: b, c1 c2, d.' produces three entries 'a b,', 'a c1 c2,', and 'a d.' in the statement table itab3.

The statement table itab3 must be a standard table without secondary keys and have the structure SSTMNT.

The statement classification characters colon, comma, and period are not written to the token table itab2. Instead, the table itab3 contains details about the position of a colon or the type (comma or period) and position of the end marker in the statement description.


System Fields sy-subrcMeaning 0Source code table is not empty, contains no errors, and is broken down into tokens. 1Source code table is not empty and is broken down into tokens, but at least one include program does not exist (can occur only in co nnection with the addition WITH INCLUDES). 2Source code table itab1 is empty or a blank row range was selected (applies to the additions FROM and TO). 4Scanner detects error in source code. 8Other error or runtime error in scanner.

If a runtime error occurs in the scanner (sy-subrc has the value 8), a database rollback is executed as usual.


Components of the Structure STOKES


The fields of the structure STOKES, and thus the columns of the token table itab2, have the following meaning:
TYPEType of token with possible values:

I (identifier)
S (string, i.e. character literal)
L (list, enclosed in parentheses)
C (comment)
B (beginning of a list)
D (separator (divider) between list elements)
E (end of a list)

Types B, D, and E can only appear if the addition WITH
LIST TOKENIZATION is specified.
ROWNumber of row where token occurs or where it begins (>= 1)
COLOffset of first character of token relative to start of row (>= 0)
STRCharacter string forming the token.

If the structure STOKEN is specified, three more fields are filled and the following must be noted:
STRThe character string forming the token contains only the first part if the character string is longer than 30.
LENLength of the token
OVFLOverflow flag for field STR with the following possible values:

SPACE (no overflow, token fits completely in field STR)
X (overflow, either not resolved (no overflow area specified) or token fits in overflow area c1))
O (overflow of token and overflow of overflow area c1)
OFF1Offset in overflow area, if

token does not fit completely in field STR and
an overflow area c1 is specified and
token fits completely in overflow area c1.


Components of the Structure SSTMNT


The fields of the structure SSTMNT, and thus the columns of the statement table itab3, have the following meaning:
TYPEType of statement with possible values:

E (Native SQL statement between EXEC SQL and ENDEXEC)
I (INCLUDE prog)
J (INCLUDE prog, prog does not exist, can occur only in connection with the addition WITH INCLUDES)
T (TYPE-POOLS pool)
V (TYPE-POOLS pool, pool does not exist)
R (call a macro from table TRMAC)
D (call a macro internally defined with DEFINE)
M (macro definition between DEFINE and END-OF-DEFINITION)
C (COMPUTE statement, sometimes without COMPUTE as first token)
A (method call in short form)
K (other ABAP key word)
N (blank statement)
P (comment between statements)
S (comment within statements)
U (unknown, non-blank statement)
LEVELIndex of source code unit in the level table itab specified after LEVELS INTO (>= 1, if level table specified, otherwise 0).
STRUCIndex of the statement in the structure table itab specified after STRUCTURES INTO (0 if the structure table is not specified or the structure in which the statement occurs could not be constructed).
FROMIndex of first token of statement in the token table itab2 (FROM = TO + 1, if the statement consists only of the end marker (comma or period))
TOIndex of last token of statement in the token table itab2 (the end marker of the statement no longer counts as a token)
NUMBERStatement counter in a source code unit. Covers all statements, regardless of how many are actually selected (in cases where a key word table itab is specified after KEYWORDS FROM)
PREFIXLENNumber of tokens before the colon (with chained statements >= 1, otherwise 0)
COLONROWRow number of colon (with chained statements >= 1, otherwise 0)
COLONCOLColumn number of colon (with chained statements >= 0, otherwise 0)
TERMINATOR End marker of a statement (normally a period or a comma, but SPACE in the case of embedded Native SQL statements and internal macro definitions)
TROWRow number of the end marker (>= 1, if TERMINATOR <(><<)>> SPACE, otherwise 0)
TCOLColumn position of the end marker (>= 0, if TERMINATOR <(><<)>> SPACE, otherwise 0)
ENHMTIndex in the enhancement table of type SENHMT, if the statement was enhanced or originates completely from an enhancement implementation. If addition ENHANCEMENTS INTO itab is not specified, this value is always 0.

RESET M2

Latest notes:When macro calls are expanded, no position specifications are available. The corresponding fields in the token table itab2 and in the statement table itab3 are then set to 0.
Unlike in the usual syntax check, the following are not treated as errors: Comma without preceding colon (the comma then acts as an end marker), Open chained statement sequence at end of source code, i.e. the last statement is closed by a comma, not by a period, Open statement at end of source code, i.e. the last statement is closed neither by a period nor by a comma.
To enable errors to be analyzed without the program being modified, the additions INCLUDE, MESSAGE, WORD, LINE, and OFFSET must be specified to gather information about the error in question.

• FROM SCAN ABAP-SOURCE (internal)
• TO SCAN ABAP-SOURCE (internal)

ABAP Addition ABAP Addition


What does it do?Breaks down the source code table itab1 into tokens not from start to finish, but only from row n1 to row n2.

The additions FROM n1 and TO n2 must, in this order, follow the specification of the source code table itab1.

RESET M2

Latest notes:When using the start specification n1, use the addition WITHOUT TRMAC to ensure that there are no unnecessary database accesses to the table TRMAC.
The end specification n2 is treated as 'soft', i.e. a statement that begins on a line <(><<)>= n2, but ends only on a line > n2, is returned completely.

If the end specification n2 splits a chained statement, only the split part up to the next comma is returned completely, not the entire chained statement up to the next period.
Negative line specifications are not allowed and produce a runtime error.
A line specification of 0 amounts essentially to no specification.
If n1 > number of rows in source code table, the scanner is not called (sy-subrc = 2).
If n1 > n2 and n2 > 0, the scanner is not called (sy-subrc = 2).

• KEYWORDS FROM SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Does not return all statements, only those specified in the key word table itab.

If the key word table is empty (i.e. it contains 0 rows), all the statements are selected.

The rows of the key word table are treated as a character field. It must be a standard table without secondary keys.

To select a Native SQL statement or a macro definition, the pseudo key words EXEC_SQL or DEFINE_MACRO can be specified. It makes no difference whether the statements EXEC or DEFINE occur as well. NativeSQL statements and macro definitions are returned as one statement (of type E or M even if the expansion of a macro definition produces more than one statement.

If the key word table contains a blank row, blank statements are also selected.

• LEVELS INTO SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Stores details about each edited source code unit (source code table itab1 itself, expanded include programs, expanded macro definitions) in the level table itab.

Specify a level table only with the additions WITH INCLUDES or WITH IMPLICIT ENHANCEMENTS.

The level table itab must have the structure SLEVEL. It must be a standard table without secondary keys.


The fields of the structure SLEVEL (and consequently the columns of the level table itab) have the following meaning:
TYPEType of source code unit with possible values:

P (program)
D (internal DEFINE macro)
R (macro from table TRMAC)
NAMEName of source code unit (name of include program, macro name)
DEPTHCurrent nesting depth of source code unit (>= 1)
LEVELIndex of superior (i.e. including or calling) source code unit in the level table (>= 1, if DEPTH >= 2, otherwise 0)
STMNTIndex of superior (i.e. including or calling) statement in the statement table (>= 1, if DEPTH >= 2, otherwise 0)
FROMIndex of first statement of source code unit in the statement table (>= 1)
TOIndex of last statement of source code unit in the statement table (>= 1)


If the source code unit contains include programs or macro calls, the row range [FROM, TO] in the statement table also covers the statements in subordinate source code units.




Latest notes: Enhancements of type E are saved as normal includes
in the level table.

• STRUCTURES INTO SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Details of the construction of the source code table itab1 are written to the structure table itab.

The structure tableitab must have the structure SSTRUC . It must be a standard table without secondary keys.


The fields in SSTRUC (which are also the columns of structure table itab) have the following meanings:
TYPEType of structure with possible values:
P (beginning of the source code)
R (subroutine)
M (macro, EXEC SQL)
I (loop)
A (case distinction)
C (condition in a case distinction)
J (jump command)
D (structured declaration)
E (event)
S (sequence of statements with simple structures)
STMNT_TYPEThe statement type of the beginning of the structure. The values are listed in the type pool SCAN in structure SCAN_STRUC_STMNT_TYPE.
KEY_STARTFlags whether the start of the structure is described semantically ('X' if there is a special statement, otherwise ' ').
KEY_ENDFlags whether the end of the structure is described semantically ('X' if there is a special statement, otherwise ' ').
STMNT_FROMIndex of the first statement of the structure in the statement table itab3.
STMNT_TOIndex of the last statement of the structure in the statement table itab3.
STRUC_FROMIndex of the first substructure of the structure in structure table itab.
STRUC_TOIndex of the last substructure of the structure in structure table itab.
BACKIndex of the structure in the structure table itab that contains the structure as a substructure (0 if the structure is the root structure of a structure tree).

• OVERFLOW INTO SCAN ABAP-SOURC (internal)E

ABAP Addition


What does it do?This addition is only allowed and required if the token table itab2 has the structure STOKEN or STOKEX.
If a token is too large to be stored in the token table in the field STR, it is placed in the overflow area c1. The offset of the token in the overflow area then lies in the token table in the field OFF1.

• WITH ANALYSIS SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Breaks down each token t = a+b(c) according to the logic of the RSYN key word ANALYSIS into its three components a, b, and c.

Offset and length of components a, b and, c are stored in the fields LEN1, OFF2, LEN2, OFF3, and LEN3 in the token table. (The offset of OFF1 is always 0 and therefore not required.)

If the addition WITH ANALYSIS is specified, the token table itab2 must have the structure STOKESX, so that the fields LEN1, OFF2, LEN2, OFF3 and LEN3 are available.

If the token table has the structure STOKEX, the following must be noted:
If the whole token exists in the token table, the offset specifications are relative to the token start. If the token is in the overflow area c1, the offset specifications are relative to the start of the overflow area.

• WITH DECLARATIONS SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Returns all declarative statements and all statements with inline declarations.

• WITH BLOCKS SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Returns all statements that define a processing block or a statement block.

• WITH COMMENTS SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Also returns comments, with each individual comment representing a token. Also writes entries for each cohesive block to the table itab3. Here, a distinction is made between comments within statements and comments at program level. In itab3, an entry for a comment within a statement always comes before the statement containing the comment.




Example ABAP Coding
Look at the following program fragment. The prefixed numbers are the indexes of the tokens.
1 * An example
2 * with scattered comments
6 MOVE
3 * inserted comment 1
7 X
4 * inserted comment 2
8 TO
9 Y
5 * inserted comment 3
.


SCAN then enters the following values for the components TYPE , FROM and TO (in this order from left to right) into itab3.
'P'12
'S'35
'K'69




Latest notes:If the addition WITH COMMENTS is used, the table
itab2 must have the row type STOKES or STOKESX.

• WITH PRAGMAS SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?This addition returns all relevant pragmas for each statement before the first correct token of the statement but after a block of comments collected with the WITH COMMENTS addition. pragmas expects a data object of the type c with length 1, usually containing the value '*'. Other values are intended for and recognized by special test tools.

A block of pragmas is combined in the statement table under the statement type 'G'. In this way, the block sequence is for a statement which contains comments and matching pragmas 'S-G-K'.

Pragmas which are not determined for ABAP Compiler are searched for in the TRPRAGMA database table.

Illegal (for example, unknown or lexically incorrect) pragmas are processed in the same way as legal pragmas, that is, they are summarized in a block preceding the actual statement (ID 'G'). This corresponds to the behavior of the scanner in the compiler.

• WITH INCLUDES SCAN ABAP-SOURCE (internal)
• IMPLEMENTATIONS FROM SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do? Also breaks down subordinate source code units (include programs, called macros) into tokens.

In addition, source code plug-ins of explicit and implicit enhancement options which may exist are automatically inserted in the source code to be split. The optional addition IMPLEMENTATIONS FROM itab can be used to limit the number of inserted enhancements to the number specified in itab. If itab is empty, any enhancements are ignored. itab must be a standard table without secondary keys.

RESET M2

Latest notes:The addition WITH INCLUDES is normally combined with the addition LEVELS INTO itab.
If (at least) one include program does not exist, sy-subrc is set to 1 and the relevant INCLUDE statement is flagged in the statement table itab3 by the statement type J (instead of I), but the breakdown process continues. The level table itab contains no entry for include programs that do not exist.
If WITH INCLUDES is combined with the addition WITHOUT TRMAC, TRMAC macros are not expanded because the system does not recognize them as subordinate source code units.
When macro calls are expanded, no position specifications are available. The corresponding fields in the token table itab2 and in the statement table itab3 are then set to 0.
The additions FRAME PROGRAM FROM and INCLUDE PROGRAM FROM are required to correctly solve the source code enhancements.

• WITH TYPE-POOLS SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?This addition has the same effect as the WITH INCLUDES addition, except that with the former, include programs belonging to type groups are broken down into tokens.

• WITH LIST TOKENIZATION SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Tokens of the form (a1, a2, a3) are not returned as tokens but broken down into the elementary components.

• PRESERVING IDENTIFIER ESCAPING SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?By default, exclamation marks before labels are deleted. Exclamation marks can be used to distinguish between labels and key words. This addition prevents their deletion.

• WITHOUT TRMAC SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?If a statement begins neither with an ABAP key word nor with a DEFINE macro, the system does not check whether this is a TRMAC macro, but assumes an unknown statement. (Unknown statements are flagged in the statement table itab3 with a U in the field TYPE.)

To avoid unnecessary database accesses to the table TRMAC, the addition WITHOUT TRMAC should be used whenever it is assumed that the source code being scanned contains unknown statements. Unknown statements are particularly likely to occur if the addition FROM n1 is used, because the scanner does not start at the beginning of the source code, but from a specified point.




Latest notes:If WITHOUT TRMAC is used with WITH INCLUDES,
TRMAC macros are not expanded because the system does not recognize them as subordinate source code units.

ABAP Addition ABAP Addition ABAP Addition ABAP Addition ABAP Addition ABAP Addition


What does it do?The above additions have the same effect as the corresponding additions in the statement SYNTAX-CHECK: c2 is an input field for a program name to be assigned to the source code, while the fields c3, c4, c5, n3 , and n4 are output fields in case an error occurs.

In Release 7.00, the addition PROGRAM FROM was renamed as INCLUDE PROGRAM FROM to clarify the difference between the master program and the split source code unit. If the addition is used in its previous form PROGRAM FROM, it sets the master program and the source code text unit to be scanned at the same time.

To be able to analyze errors without modifying programs, use the additions INCLUDE INTO, MESSAGE INTO, WORD INTO, LINE INTO and OFFSET INTO. These provide information about the errors which have occurred.

• WITH EXPLICIT ENHANCEMENTS SCAN ABAP-SOURCE (internal)

ABAP Addition FROM itab]


What does it do?When WITH EXPLICIT ENHANCEMENTS is specified, the existing source code plug-ins for explicit enhancement points are automatically inserted into the split source code.

The optional addition IMPLEMENTATIONS FROM can limit the number of inserted enhancements to the number specified in itab. If itab is empty, any enhancements are ignored.

• WITH IMPLICIT ENHANCEMENTS SCAN ABAP-SOURCE (internal)

ABAP Addition FROM itab]


What does it do?When WITH IMPLICIT ENHANCEMENTS is specified, the existing source code plug-ins for implicit enhancement points are automatically inserted into the split source code.

The optional addition IMPLEMENTATIONS FROM can limit the number of inserted enhancements to the number specified in itab. If itab is empty, any enhancements are ignored.

• ENHANCEMENT OPTIONS INTO SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Specifications about the enhancement points that exist in the source code unit that is being processed are stored in the itab description table. It therefore only makes sense to specify an enhancement table together with additions WITH INCLUDES, WITH EXPLICIT ENHANCEMENTS, or WITH IMPLICIT ENHANCEMENTS.

The level table itab must be a standard table without a secondary key and must have the row structure SEOPTN whose fields have the following meaning:
LEVELIndex of the relevant entry in the level table. If this information is required, the LEVELS INTO addition must be specified at the same time in order to fill the level table.
ROW, COLPosition of the enhancement point in the source code. This position is not unique, since enhancements can be inserted to all blanks around the position specified by ROW and COLUMN .
FULL_NAMEFull name of the enhancement point. This name uniquely identifies an implicit enhancement point.
TYPEThe type of enhancement point. I is for an implicit enhancement point and E is for an explicit enhancement point.
MODEThe mode of the enhancement point. Type S is for static, type D is for dynamic, and type A is for any enhancement point.
ENHMTIndex of the first relevant enhancement implementation in the enhancement table or 0 if the enhancement point is not implemented. If this information is required, the ENHANCEMENTS INTO addition must be specified at the same time in order to fill the enhancement table.


Latest notes:The additions FRAME PROGRAM FROM and INCLUDE PROGRAM FROM are used, especially for explicit enhancement points, to find out the name of the master program or the name of the current include program. These names are used to determine the full names of explicit enhancement points. The ENHANCEMENT OPTIONS INTO addition is independent of the ENHANCEMENTS INTO addition and they can be used at the same time.

• ENHANCEMENTS INTO SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Specifications of the enhancement implementations available in the source code that is processed are saved in enhancement table itab. It therefore only makes sense to specify an enhancement table together with additions WITH INCLUDES, WITH EXPLICIT ENHANCEMENTS, or WITH IMPLICIT ENHANCEMENTS.

The enhancement table itab must be a standard table without secondary keys and have the row structure SENHMT, whose fields have the following meaning:
ENHMTThe index of the superior enhancement.
STMNTThe index of the statement in the statement table to which the enhancement is connected (such as ENHANCEMENT-POINT for explicit enhancements or METHOD for an implicit enhancement of a method implementation).
FROMWith regular enhancements (type 'E'), this is the index of the first statement of the enhancement in the statement table. With fragmentary enhancements (type 'F'), this is the index of the first token of the enhancement in the token table.
TOWith regular enhancements (type 'E'), this is the index of the last statement of the enhancement in the statement table. With fragmentary enhancements (type 'F'), this is the index of the first token of the enhancement in the token table.
NAMEName of the enhancement.
INCLUDEName of the include that contains the implementation of the enhancement.
IDInternal ID of the enhancement implementation within the implementation include.
TYPEType of the enhancement. Type 'E' stands for a normal enhancement with one or more complete statements. Type 'F' stands for a fragmentary enhancement of one or more tokens within an individual statement.
MODE Mode of the enhancement: 'D' (dynamic) or 'S' (static).


Latest notes:For enhancements to be identified correctly, it is imperative that the additions FRAME PROGRAM FROM and INCLUDE PROGRAM FROM are specified correctly. Multiple fragmentary enhancements can exist for a statement. In this case, the statement table refers to the entry in the first enhancement in the enhancement table; all other enhancements are connected directly to this and can be identified uniquely using the STMNT field. The ENHANCEMENT INTO addition is independent of the ENHANCEMENTS OPTIONS INTO addition and they can be used at the same time.

• WITH INACTIVE ENHANCEMENTS SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?This addition is only possible with ENHANCEMENTS INTO . If WITH INACTIVE ENHANCEMENTS is specified as well, deactivated or overwritten enhancement implementations are respected. For these, the values 'e' and 'f' are stored instead of 'E' and 'F' in the TYPE column of the itab enhancement table.

• FRAME PROGRAM FROM SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Using this addition, the master program is specified to the source code unit to be split. This is necessary, especially for inserting source code plug-ins correctly.



Latest notes:For the master program, remember that even when this
addition from the SCAN statement is specified, processing does not occur at the same time. The SCAN statement always processes only the passed source code and possibly the included type groups or include programs. In order to process an include program in its context, the master program must be passed itself, whereby non-relevant include programs with the REPLACING addition can be hidden. As an alternative to the use of REPLACING, a mock master program, which constructs the correct context for include programs to be processed but remains empty the rest of the time, is also possible.

• REPLACING SCAN ABAP-SOURCE (internal)

ABAP Addition


What does it do?Individual INCLUDE statements can be overridden by specifying an internal table of type SREPTAB. If itab contains an entry 'INCL' in column name, with the statement INCLUDE incl not the include INCL is read but the source code from column itab-source is inserted.

It has the same effect as the addition REPLACING of the internal statement SYNTAX-CHECK FOR PROGRAM. However, the entry itab-trdir is ignored.

itab must be a standard table without secondary keys.
