assign customized screen to absence type

Dear Gurus,

Do you have any idea that how could it work to assign customized screen to absence type via T554S?

If I do so directly, the system will pop up error message "a valid dynpro number has not been specified". It looks like only screen 2000~2008 etc is valid range.

However, we have a special requirement to display P2001-ABRST & P2001-ABRTG of payroll days and payroll hours on quota deduct absence screen.

Screen 2001 doesn't include these two fields.

So I copied screen 2001 out to new screen 9001 via SE51 MP200000. Though it test OK doesn't work at T554S level.

Appreciate your kindly advice.

Best Regards,

Alina
