Hi Ronaldo,
Goto the output messages screen.
Find the output types which are marked to be triggered immediately.
Find the output programs assigned to the output types.
This program is the one which is throwing the extra screen.
Use RSNAST0D program to re-trigger the output message and debug the program to find where the screen is coming from. Put a breakpoint in the entry routine of the output program before you execute RSNAST0D.
Thanks,
Juwin
