ABAP code example for Function Module CLMA_CLASS_LIST

The ABAP code below is a full code listing to execute function module CLMA_CLASS_LIST 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:

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:

 TYPE KLAH-CLASS ,
it_tclasses
 
 TYPE STANDARD TABLE OF CLCLASS ,

 LIKE LINE OF it_tclasses,

 TYPE KLAH-KLART ,
ld_language
 
 TYPE SY-LANGU ,
ld_with_allocations
 
 TYPE RMCLM-ANZUKZ ,
ld_key_date
 
 TYPE KSSK-DATUV ,
ld_allocations
 
 TYPE RMCLM-ANZUKZ ,
ld_change_number
 
 TYPE RMCLM-AENNR .



SELECT single CLASS 
  FROM KLAH

SELECT single KLART
