ABAP code example for Function Module KFM_KF_BUFFER_READ

The ABAP code below is a full code listing to execute function module KFM_KF_BUFFER_READ 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_et_outtab  
 
 TYPE ANY TABLE

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

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

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_et_outtab
 
 TYPE ANY TABLE ,
ld_iv_operation
 
 TYPE CHAR3 ,
ld_iv_db_table_ref
 
 TYPE DDOBJNAME ,
ld_iv_clear_table
 
 TYPE XFELD .


ld_iv_operation = 'Check type of data required'.
ld_iv_db_table_ref = 'Check type of data required'.
ld_iv_clear_table = 'Check type of data required'.
