ABAP code example for Function Module WP_CUSTOM_GET

The ABAP code below is a full code listing to execute function module WP_CUSTOM_GET 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_itemdescription  
 
 TYPE WPDESCR
,
ld_itemvalue  
 
 TYPE WPVALUE
.


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

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

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

CALL FUNCTION 'WP_CUSTOM_GET'
  EXPORTING

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_itemdescription
 
 TYPE WPDESCR ,
ld_groupid
 
 TYPE WPGROUPID ,
ld_itemvalue
 
 TYPE WPVALUE ,
ld_itemid
 
 TYPE WPITEMID ,
ld_langu
 
 TYPE LANG .


ld_groupid = 'Check type of data required'.
ld_itemid = 'Check type of data required'.
ld_langu = 'Check type of data required'.
