Message Handling in HCM Process and Forms

Question

Hi,
I have added own messages logic
MESSAGE_HANDLER Type Ref To     IF_HRBAS_MESSAGE_HANDLER
          message_handler->add_message( message = message ).
in "DO_OPERATION" method of Generic Service in HCM process and Forms.
Problem : We have handled messages in method "DO_OPERATION"  but when we click on NEXT push button (review and send)at mss level, same error messages is displayed for 2 times above the adobe form.
Same error messages are displayed as many times as we click on NEXT push button.
Need Solution : It is supposed to display only once.
Thank You,
Swetha.C

Hi Shweta,
Please check SY-UCOMM in both the cases.
1. After Selecting Position
2. After Clicking 'Next' Button.
If SY-UCOMM is different, Then Add message to Message_handler only when Position is selected.
That means If sy-ucomm = Position select User command
Then Add message to Message_handler.
endif.
'Else dont ADD'
Hope this helps.
Pradeep.
