ABAP code example for Function Module WRSZ_SINGLE_READ

The ABAP code below is a full code listing to execute function module WRSZ_SINGLE_READ 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).

ld_wrsz_out  
 
 TYPE WRSZ
.

 

SELECT single ASORT 
  FROM WRSZ 
  INTO @DATA(ld_asort).

 

SELECT single LFDNR

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_wrsz_out
 
 TYPE WRSZ ,
ld_asort
 
 TYPE WRSZ-ASORT ,
ld_lfdnr
 
 TYPE WRSZ-LFDNR .



SELECT single ASORT 
  FROM WRSZ 
  INTO ld_asort.


SELECT single LFDNR 
  FROM WRSZ 
  INTO ld_lfdnr.
