ABAP code example for Function Module CHECK_EXIST_CLAS

The ABAP code below is a full code listing to execute function module CHECK_EXIST_CLAS 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_exist  
 
 TYPE SXST_PARE-EXIST
.

 

SELECT single OBJ_NAME 
  FROM TADIR 
  INTO @DATA(ld_name).

 

SELECT single PGMID 
  FROM TADIR 
  INTO @DATA(ld_mtype).

.

CALL FUNCTION 'CHECK_EXIST_CLAS'
  EXPORTING
    name =                       ld_name
*   mtype =                      ld_mtype
  IMPORTING
    exist =                      ld_exist
  EXCEPTIONS
    TR_INVALID_TYPE =            1

ABAP code to compare 7.40 inline data declaration with original syntax

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.

DATA:

ld_exist
 
 TYPE SXST_PARE-EXIST ,
ld_name
 
 TYPE TADIR-OBJ_NAME ,
ld_mtype
 
 TYPE TADIR-PGMID .



SELECT single OBJ_NAME 
  FROM TADIR 
  INTO ld_name.


SELECT single PGMID 
  FROM TADIR 
  INTO ld_mtype.
