ABAP code example for Function Module MD_READ_RULES





The ABAP code below is a full code listing to execute function module MD_READ_RULES 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_p_i_wmpkd    TYPE WMPKD
,
ld_p_i_wmprt    TYPE WMPRT
,
it_p_t_wmprd    TYPE STANDARD TABLE OF WMPRD,"TABLES PARAM
wa_p_t_wmprd  LIKE LINE OF it_p_t_wmprd
.



 

SELECT single MPRNR 
  FROM WMPR 
  INTO @DATA(ld_p_i_mprnr).

 

"populate fields of struture and append to itab
append wa_p_t_wmprd to it_p_t_wmprd.

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_p_i_wmpkd  TYPE WMPKD ,
ld_p_i_mprnr  TYPE WMPR-MPRNR ,
it_p_t_wmprd  TYPE STANDARD TABLE OF WMPRD ,
wa_p_t_wmprd  LIKE LINE OF it_p_t_wmprd,
ld_p_i_wmprt  TYPE WMPRT .





SELECT single MPRNR 
  FROM WMPR 
  INTO ld_p_i_mprnr.
 

"populate fields of struture and append to itab
append wa_p_t_wmprd to it_p_t_wmprd.
