ABAP code example for Function Module CUD0_READ_KNOWLEDGE_FROM_DB

The ABAP code below is a full code listing to execute function module CUD0_READ_KNOWLEDGE_FROM_DB 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).

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_date
 
 TYPE CUKB-DATUV ,
it_knowledge
 
 TYPE STANDARD TABLE OF RKNOBJ ,
wa_knowledge
 
 LIKE LINE OF it_knowledge,
ld_compilat
 
 TYPE STRING ,
it_v_cuob_v1
 
 TYPE STANDARD TABLE OF CUOB_V1 ,
wa_v_cuob_v1
 
 LIKE LINE OF it_v_cuob_v1,
ld_source
 
 TYPE STRING ,
ld_suppress_dialog
 
 TYPE C .



SELECT single DATUV 
  FROM CUKB 
  INTO ld_date.
 

"populate fields of struture and append to itab
append wa_knowledge to it_knowledge.
ld_compilat = 'some text here'. 

"populate fields of struture and append to itab
append wa_v_cuob_v1 to it_v_cuob_v1.
ld_source = 'some text here'.
