ABAP code example for Function Module DEQUEUE_E_MERGE

The ABAP code below is a full code listing to execute function module DEQUEUE_E_MERGE 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_mode_mergeh) = 'Check type of data required'.
 

SELECT single ID 
  FROM MERGEH 
  INTO @DATA(ld_id).

 

SELECT single MAPNAME 
  FROM MERGEH

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.
