Unable to debug F110 - Payment Advice Script

Hi All,

I am unable to debug Payment Advice SAP Script - ZF110_IN_AVIS. While Printing, F110 is creating background job and is creating a spool request. I would like to break before printing in the Print program.

Can anyone suggest me how to break in print program when printing goes to background mode?.

FYI:

I tried activating Debugging option both at script level, have put break point in print program etc and it did not work.

Many thanks ,

Rama
