ABAP code example for Function Module BM_VARIANT_ENQUEUE_DEQUEUE

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

 

SELECT single VARIANT_ID 
  FROM DF50L 
  INTO @DATA(ld_variant).

 

SELECT single AS4LOCAL 
  FROM DF50L 
  INTO @DATA(ld_as4local).


DATA(ld_enqueue_variant) = 'some text here'.

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_variant
 
 TYPE DF50L-VARIANT_ID ,
ld_as4local
 
 TYPE DF50L-AS4LOCAL ,
ld_enqueue_variant
 
 TYPE STRING .



SELECT single VARIANT_ID 
  FROM DF50L 
  INTO ld_variant.


SELECT single AS4LOCAL 
  FROM DF50L 
  INTO ld_as4local.

ld_enqueue_variant = 'some text here'.
