ABAP code example for Function Module DD_DETERMINE_IPARAM_SOURCE

The ABAP code below is a full code listing to execute function module DD_DETERMINE_IPARAM_SOURCE 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_source  
 
 TYPE RSX12DB-SOURCE

SELECT single DBINDEX 
  FROM DD12L 
  INTO @DATA(ld_dbindex).

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_source
 
 TYPE RSX12DB-SOURCE ,
ld_dbindex
 
 TYPE DD12L-DBINDEX ,
ld_dbsys
 
 TYPE SY-DBSYS ,
ld_tabname
 
 TYPE DD02L-TABNAME ,
ld_tsource
 
 TYPE RSX02DB-SOURCE ,
ld_ref_index
 
 TYPE DD12L-DBINDEX .



SELECT single DBINDEX 
  FROM DD12L 
  INTO ld_dbindex.

ld_dbsys = 'some text here'.

SELECT single TABNAME 
  FROM DD02L 
  INTO ld_tabname.


ld_tsource = some text here

SELECT single DBINDEX 
  FROM DD12L 
  INTO ld_ref_index.
