ABAP code example for Function Module MVAN_CHANGE_CHECK

The ABAP code below is a full code listing to execute function module MVAN_CHANGE_CHECK 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_flgaen
 
 TYPE SY-DATAR ,
ld_irmmg1
 
 TYPE RMMG1 ,
it_xdmvan
 
 TYPE STANDARD TABLE OF XDMLAN ,
wa_xdmvan
 
 LIKE LINE OF it_xdmvan,
ld_flg_array
 
 TYPE T130F-KZREF ,
it_ydmvan
 
 TYPE STANDARD TABLE OF XDMLAN ,
wa_ydmvan
 
 LIKE LINE OF it_ydmvan.


ld_irmmg1 = 'Check type of data required'. 

"populate fields of struture and append to itab
append wa_xdmvan to it_xdmvan.

SELECT single KZREF 
  FROM T130F 
  INTO ld_flg_array.
 

"populate fields of struture and append to itab
