Validation on step change in GAF

[Former Member]

Hi All,

I am developing an application using GAF component. I have to perform some validation before i move from one step to the other. I didnt not find any FPM event getting triggered on step change (or Prevoius.Next button).

Please let me know how and where i can perform this validation and also provide appropriate error message.

Thanks,

Pris.

Hi Prisford,

When ever you click on NEXT step or PREVIOUS  button then it will got to Process Event.

In the PROCESS_EVENT of the feeder class you can write code like this.

  CASE io_event->mv_event_id.

     WHEN cl_fpm_event=>gc_event_next_step.

       check_input_fields( IMPORTING ev_result = ev_result

                                     et_messages = et_messages ).

   ENDCASE.
