While Assigning a Feeder Class in Component Configuration Throws an error

sandeep_suggu — Wed, 11 Jan 2023 14:27:16 GMT

HI SCN People,

For List

Web Dynpro Components/Interfaces - FPM_LIST_UIBB_ATS

In Case of Class - I used Interface (IF_FPM_GUIBB_LIST) & written the code in a method (IF_FPM_GUIBB_LIST~GET_DEFINITION)

  method IF_FPM_GUIBB_LIST~GET_DEFINITION.

    eo_field_catalog ?= cl_abap_structdescr=>describe_by_name( 'structure_name' ).

  endmethod.

Thank You,

Suggu Sandeep.

Hi Sandeep,

The exporting parameter EO_FIELD_CATALOG must be of type CL_ABAP_TABLEDESCR, not of type CL_ABAP_STRUCTDESCR. Casting the latter to the first is not possible.

Best regards
Jens

HI jens.ruths,

Thank You.

I modified the code in another way,
It's working now.

  METHOD if_fpm_guibb_list~get_definition.

    DATA: lt_porg TYPE TABLE OF ZDATA_BILL_LIST.

    eo_field_catalog ?= cl_abap_typedescr=>describe_by_data( lt_porg ).

  ENDMETHOD.
