Debugging UserExits?

Hi,

RFC FM "CIF_PIR_INBOUND" is called from APO. This FM

calls customer function through CALL CUSTOMER-FUNCTION '001'.

Exit name is "EXIT_SAPLCPIR_001" & include is "INCLUDE ZXCIFU15".

I have implemented this userexit in Deveopment environment, while debugging FM "CIF_PIR_INBOUND"

control passes through exit FM "EXIT_SAPLCPIR_001".

The same request is transported into Quality Environment.

While debugging control does not passes through exit FM "EXIT_SAPLCPIR_001".

Observations:

1. Do not have development authorization in Quality Server.

2. All objects transported with status active.

I need to debug the userexit in Quality Server. Is there any way to debug it?

Valuable input please.

Best Regards,

Priyanka
