ABAP code example for Function Module T421_READ

The ABAP code below is a full code listing to execute function module T421_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).

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_struct
 
 TYPE T421 ,
ld_logrp
 
 TYPE T421-LOGRP ,
ld_text
 
 TYPE T421T-TXT ,
ld_spras
 
 TYPE T421T-SPRAS ,
ld_werks
 
 TYPE T421-WERKS .



SELECT single LOGRP 
  FROM T421 
  INTO ld_logrp.


SELECT single SPRAS 
  FROM T421T 
  INTO ld_spras.


SELECT single WERKS 
  FROM T421 
  INTO ld_werks.
