ABAP code example for Function Module VKKSA_SIMULATE_OP

The ABAP code below is a full code listing to execute function module VKKSA_SIMULATE_OP 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).

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_i_gpart
 
 TYPE DFKKOP-GPART ,
it_t_fkkop
 
 TYPE STANDARD TABLE OF FKKOP ,
wa_t_fkkop
 
 LIKE LINE OF it_t_fkkop,
ld_i_vtref
 
 TYPE DFKKOP-VTREF ,
ld_i_waers
 
 TYPE DFKKOP-WAERS ,
ld_i_date_to
 
 TYPE SY-DATUM .



SELECT single GPART 
  FROM DFKKOP 
  INTO ld_i_gpart.
 

"populate fields of struture and append to itab
append wa_t_fkkop to it_t_fkkop.

SELECT single VTREF 
  FROM DFKKOP 
  INTO ld_i_vtref.


SELECT single WAERS 
  FROM DFKKOP 
  INTO ld_i_waers.

ld_i_date_to = '20210129'.
