    • It is used for Buliding the Field catalog for LVC grid function and OOALV function.

      it is possible to Build fieldcatalog only based on the DDIC structure using the above mentioned function.

      LVC fieldcatalog is different from SLIS fieldcatalog in definition and Some extra additions also there...

    so can i pass my internal table ref into this functional module or it is mandotry to pass ref of DDIC object only ???

    will i pass my own i_structure_name in this functional module??

    call function 'LVC_FIELDCATALOG_MERGE'
           exporting
                i_structure_name = 'SFLIGHT'
           changing
                ct_fieldcat      = gt_fieldcatalog.

    how can we pass our own structure / field catalog in this functional module ???

      Hello Ankesh

      You cannot use internal tables but have to refer to tables/structures in the DDIC.

      If I need to build up a fieldcatalog consisting of field from different structure I simply call this fm with all the required structures and afterwards delete the obsolete columns (= records).

      Regards

      Uwe

    i feel its basic question as it performs same task as reuse_alv_field_catalog_merge. ofcorse its object oriented

    Also help.sap.com is working

    Do you think so?
