ABAP code example for Function Module RKE_READ2_READ_FROM_JOIN





The ABAP code below is a full code listing to execute function module RKE_READ2_READ_FROM_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).

DATA:
ld_timestmp    TYPE CEDDB-TIMESTMP
,
it_seltab    TYPE STANDARD TABLE OF CEDST,"TABLES PARAM
wa_seltab  LIKE LINE OF it_seltab
,
it_sftab    TYPE STANDARD TABLE OF CFBSF01,"TABLES PARAM
wa_sftab  LIKE LINE OF it_sftab
.



 

SELECT single ERKRS 
  FROM TKEB 
  INTO @DATA(ld_erkrs).



DATA(ld_form) = some text here


DATA(ld_program) = some text here

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

"populate fields of struture and append to itab
append wa_seltab to it_seltab.

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_timestmp  TYPE CEDDB-TIMESTMP ,
ld_erkrs  TYPE TKEB-ERKRS ,
it_seltab  TYPE STANDARD TABLE OF CEDST ,
wa_seltab  LIKE LINE OF it_seltab,
ld_form  TYPE CEDDB-DATAFORM ,
it_sftab  TYPE STANDARD TABLE OF CFBSF01 ,
wa_sftab  LIKE LINE OF it_sftab,
ld_program  TYPE CEDDB-PROGRAM ,
ld_debug_mode  TYPE KED7_CHAR1 .





SELECT single ERKRS 
  FROM TKEB 
  INTO ld_erkrs.
 

"populate fields of struture and append to itab
append wa_seltab to it_seltab.

ld_form = some text here 

"populate fields of struture and append to itab
