The ABAP code below is a full code listing to execute function module CALL_EXTERN_FORM including all data declarations. The code uses the latest in-line data DECLARATION SYNTAX but I have included an ABAP code snippet at the end to show how declarations would look using the original method of declaring data variables up front. This will allow you to compare and fully understand the new inline method. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8).
DATA(ld_program_name) = 'some text here'.
DATA(ld_uprog) = 'some text here'. . CALL FUNCTION 'CALL_EXTERN_FORM' EXPORTING program_name = ld_program_name uprog = ld_uprog EXCEPTIONS PROGRAM_NOT_FOUND = 1 FORM_NOT_FOUND = 2 . " CALL_EXTERN_FORM
IF SY-SUBRC EQ 0. "All OK ELSEIF SY-SUBRC EQ 1. "Exception "Add code for exception here ELSEIF SY-SUBRC EQ 2. "Exception "Add code for exception here ENDIF.
The below ABAP code uses the older none in-line data declarations. This allows you to see the coding differences/benefits of the later inline syntax. It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8.
