Syntax Cleanup in Release 7.0 For Release 7.0, the ABAP syntax has been cleaned up. Incorrect language constructs, which previously only led to syntax warnings, now cause syntax errors. The profile parameter abap/warn2error_release can be used to control whether the new syntax errors continue to be reported as syntax warnings. The following tables show the situations that lead to syntax errors as of Release 7.0. An 'X' in the final column of the table indicates that the syntax in question already led to a syntax error in classes before Release 7.0. Error in Language Construct Program Layout Statement cannot be reached.X Missing forward declaration of a class with CLASS - DEFERRED- Declarations Program-internal name with more than 30 characters.X Special characters in a program-internal name outside of Unicode programs.X Single digit as the name of a data object.X Incorrect namespace prefix.X Operational statement within the definition of a structure with BEGIN OF ...

X Line-exceeding element of a bulleted list.X Invalid use of a text symbol as the target of a call.- Internal table does not have the structure of a selection table in a comparison expression after IN.X Assignment of sy-subrc to a CHANGING, EXPORTING, or RETURNING parameter.X Passing of a data object to a formal parameter typed with STRUCTURE in a Unicode program, where the Unicode fragment view does not match completely.- Specification of a data object whose name contains an address specification such as an instance component selector or an offset/length specification, without an explicit assignment to a parameter when using EXPORT , IMPORT, or CALL DIALOG.X Internal Tables Definition of a table type for a hashed table without specifying UNIQUE before KEY.- Specification of a non-index table after SEARCH.X Incompatible work area for control level processing using internal tables with AT and SUM .X Specification of a component of a structured field symbol as a sort criterion after SORT. Database Accesses Columns of type STRING or RAWSTRING in aggregate expressions, grouping, sort keys of SELECT.- Access to a projection view in connection with a correlated subquery. Too many subqueries in a SELECT statement.- Work area or rows of an internal table are shorter than the structure of the database table when specifying the rows in DELETE dbtab.- Indicator variable in Native SQL, which is not of the external type INT2.- List Statements Dynamic position specification in WRITE or ULINE without AT.X Negative length specification len after WRITE AT.- Specification of a write-protected data object after HIDE.X
