ABAP code example for Function Module SUBST_GET_PAST_REL

The ABAP code below is a full code listing to execute function module SUBST_GET_PAST_REL 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_ev_release  
 
 TYPE UVERS-OLDRELEASE
,
ld_ev_next_release  
 
 TYPE UVERS-NEWRELEASE
.


DATA(ld_iv_datum) = '20210129'.

DATA(ld_iv_uzeit) = 'Check type of data required'.
.

CALL FUNCTION 'SUBST_GET_PAST_REL'
  EXPORTING
    iv_datum =                   ld_iv_datum

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_ev_release
 
 TYPE UVERS-OLDRELEASE ,
ld_iv_datum
 
 TYPE SY-DATUM ,
ld_ev_next_release
 
 TYPE UVERS-NEWRELEASE ,
ld_iv_uzeit
 
 TYPE SY-UZEIT .


ld_iv_datum = '20210129'.
ld_iv_uzeit = 'Check type of data required'.
