ABAP code example for Function Module BAPI_EXT_LOOP_BACK

The ABAP code below is a full code listing to execute function module BAPI_EXT_LOOP_BACK 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_return  
 
 TYPE BAPIRET2
.


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

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

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

CALL FUNCTION 'BAPI_EXT_LOOP_BACK'
  EXPORTING
    i_external_user_name =       ld_i_external_user_name

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_return
 
 TYPE BAPIRET2 ,
ld_i_external_user_name
 
 TYPE XMILOGEUSR ,
ld_destination
 
 TYPE BTC_EXT_SDL_DEST ,
ld_isolation_group
 
 TYPE BTC_EXT_ISOL_GROUP .


ld_i_external_user_name = 'Check type of data required'.
ld_destination = 'Check type of data required'.
ld_isolation_group = 'Check type of data required'.
