ARTICLE Standard SAP Help for MACRO
Inserting Macros
Syntax macro [p1 p2 ... ].>
Effect If a macro is executed instead of a valid ABAP keyword>, as the first word in an ABAP statement, its statements are included at this position in the source text. Suitable ABAP words or operands p1 p2 ... > must be transferred to all of the macro's placeholders. The specified operands p1 p2 ... > replace the placeholders sequentially. The characters are converted to uppercase (except for the content of character literals). The ABAP Compiler> searches for a macro specified in a program, first in the preceding source text of the same compilation unit> and then in the type groups> which are used for the program. Local macros of the program hide macros of the same name in type groups. A macro can insert other macros but not itself.
Notes
Previously, a specified macro not defined in the current program was only searched for in explicitly loaded type groups> using the TYPE-POOLS>> statement. The search now covers all usable type groups.
If the ABAP Compiler> does not find a specified macro in the current program or in a type group>, it searches in the TRMAC> table. Macros in the TRMAC> table usually follow different name conventions to those in type groups and therefore nothing should be hidden.
Example In this example, the two macros operation> and output> are defined. output> is nested in operation>. operation> is called three times with different parameters. Note how the placeholders <(> <)>1>, <(> <)>2>, ... are replaced in the macros. DATA: result TYPE i, n1 TYPE i VALUE 5, n2 TYPE i VALUE 6.
