Problem with Z payroll function for India Payroll

Dear Gurus,

I am facing a unique error in Z payroll function.

I have created a Z payroll function Z_INC through PE04. Once created and activated we need to go to payroll driver

HINCALC0>>Include PCASFin0.

There we will have a perform FUZ_INC.

Double click on that and create subroutine in PCBURZIN0. I have written my custom code there and then activated it.

I saved both Z function Z_INC as well as PCBURZIN0 in the same TR.

I did the test in development system (we have a test client in dev server). Once satisfied with the tests I released the TR and imported it to Quality system.

However when I login to the QAS system and go in PE04 , give Z_INC there and click on source code I get the following error:

Form routine FUZ_INC could not be found in program HINCALC0.

But my form FUZ_INC is residing in PCBURZIN0 in quality system. I dont understand where am I going wrong.

Please help , its very urgent we have a go live pending on this.
