HR FORMS: PAYSLIP

Hi, I have a requirement where we need to create a custom payslip.

I was thinking of modifying the standard HR forms for payslip for international country grouping and then modify it by removing unneeded part.

But after I copied it based on my country grouping(34) and then I tried to activate it. But it resulted to an error related to the print program. When I check the print program, the error said that there are no structure HR_PY****** on the DDIC.I thought the structure was supposedly generated automatically?

Does anybody here has ever found problem like this, Or could someone share some knowledge in building a payslip form.

Many Thanks
