Re: Check on Settlement Rule in IW31

Have a look at  exit IWO10009

* get settlement rules from ABAP memory

  call function 'K_SETTLEMENT_RULE_GET'

    exporting

      objnr     = p_caufvd_imp-objnr

      x_all     = ' '

    tables

      e_cobra   = lt_cobra

      e_cobrb   = lt_cobrb

    exceptions

      not_found = 1

      others    = 2.

  if not sy-subrc = 0.

* if not found, then go to database for settlement rules

    call function 'K_SRULE_READ_ARCHIVE'

      exporting

        i_archive_handle1 = 0

        i_objnr          = p_caufvd_imp-objnr

        i_append         = ' '

      tables

        t_cobra          = lt_cobra

        t_cobrb          = lt_cobrb

      exceptions

        not_enough_info  = 1

        others           = 2.

  endif.

Make the validations you need.

Hope it helps, saludos!
