ABAP code example for Function Module RKE_READ2_MAKE_JOIN

The ABAP code below is a full code listing to execute function module RKE_READ2_MAKE_JOIN 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 ERKRS 
  FROM TKEB 
  INTO @DATA(ld_erkrs).


DATA(ld_projektion) = 'Check type of data required'.
 

SELECT single TABNAME 
  FROM DD02L 
  INTO @DATA(ld_projektion_name).

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_erkrs
 
 TYPE TKEB-ERKRS ,
ld_projektion
 
 TYPE KED7_FIELD_LIST ,
ld_projektion_name
 
 TYPE DD02L-TABNAME .



SELECT single ERKRS 
  FROM TKEB 
  INTO ld_erkrs.

ld_projektion = 'Check type of data required'.

SELECT single TABNAME 
  FROM DD02L 
  INTO ld_projektion_name.
