irst of all you have to define your user exit in the FORM routine GET_EXIT_TITLES with the correct exit type (EXITS-PARAM). The exit type required for your FORM routine is C_EXIT_PARAM_CLASS A where complete type is transferred as a parameter. Bear in mind that this exit type can only be used for callup points with complete documents (3). Hereafter an example for your issue exits-name = 'USDN' . exits-param = c_exit_param_class . exits-title = 'SDN Test 4 GSBER Substitution' . append exits . *&---------------------------------------------------------------------* *& USER EXIT USDN *&---------------------------------------------------------------------* * GSBER substitution *----------------------------------------------------------------------* form usdn using bool_data type gb002_015 . data wa_bseg type bseg . loop at bool_data-bseg into wa_bseg where koart = 'K' . exit. endloop. .
