RSU5_SAPI_BADI

Question

Hi All,
             I have implemeted this BADI. but the problem is when activate data_transform it is throwing error on this two statements if i comment these two statements . I can only extract those datasources which have methods in this badi all other data sources are going to dump please hepl me to correct.
check BW system
check checkbw_system( ) = 'X'.
check method is implemented
CHECK checkmethod_exists( lv_method ) = 'X'.
We impliment the methods for only which we are enhancing but all the data sources creating method is difficult.
Please help me.
Thanks in advance

Answer 1

Hi,
In this we can populate the datasource enhancement code under the main method.
                                                                                method IF_EX_RSU5_SAPI_BADI~DATA_TRANSFORM.
      DATA: ls_oltpsource TYPE rsaot_s_osource,
      lv_data TYPE REF TO data,
      lv_method TYPE seocmpname.
      FIELD-SYMBOLS: <lt_data> TYPE STANDARD TABLE.
check BW system*
       check checkbw_system( ) = 'X'.
check if any data is extracted
CHECK c_t_data IS NOT INITIAL.
CALL FUNCTION 'RSA1_SINGLE_OLTPSOURCE_GET'
EXPORTING
        i_oltpsource = i_datasource
        i_objvers = 'A'
IMPORTING
       e_s_oltpsource = ls_oltpsource
EXCEPTIONS
       no_authority = 1
       not_exist = 2
       inconsistent = 3
OTHERS = 4.
       IF sy-subrc <> 0
       EXIT.
ENDIF.
create data for Extract Structure
CREATE DATA lv_data TYPE TABLE OF (ls_oltpsource-exstruct).
ASSIGN lv_data->* TO <lt_data>.
ASSIGN c_t_data TO <lt_data>.
get method name for datasource
  lv_method = i_datasource.
to populate datasource enhacement code
CASE i_datasource.
WHEN <datasource name> .
code to populate the data source enhanced field data.
ENDCASE.
