ABAP code example for Function Module J_2GRST





The ABAP code below is a full code listing to execute function module J_2GRST 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_e_rc    TYPE SY-SUBRC
,
ld_e_dsdrc    TYPE SY-SUBRC
,
ld_e_msg    TYPE J_2GLPTXT-LINE
,
it_t_statinf    TYPE STANDARD TABLE OF J_2GLPTXT,"TABLES PARAM
wa_t_statinf  LIKE LINE OF it_t_statinf
.



 

SELECT single DEVID 
  FROM J_2GLPDSD 
  INTO @DATA(ld_i_devid).

 

"populate fields of struture and append to itab
append wa_t_statinf to it_t_statinf.
.

CALL FUNCTION 'J_2GRST'
  EXPORTING
    i_devid =                    ld_i_devid
  IMPORTING
    e_rc =                       ld_e_rc
    e_dsdrc =                    ld_e_dsdrc
    e_msg =                      ld_e_msg
* TABLES
*   t_statinf =                  it_t_statinf
    .  "  J_2GRST

IF SY-SUBRC EQ 0.
  "All OK
ENDIF.







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_e_rc  TYPE SY-SUBRC ,
ld_i_devid  TYPE J_2GLPDSD-DEVID ,
it_t_statinf  TYPE STANDARD TABLE OF J_2GLPTXT ,
wa_t_statinf  LIKE LINE OF it_t_statinf,
ld_e_dsdrc  TYPE SY-SUBRC ,
ld_e_msg  TYPE J_2GLPTXT-LINE .





SELECT single DEVID 
  FROM J_2GLPDSD 
  INTO ld_i_devid.
 

"populate fields of struture and append to itab
append wa_t_statinf to it_t_statinf.
