Debugging in F110 for for payment proposal Run

Folks,

I ran into weird issue with F110. I am creating a payment proposal and system cant create payment proposal due to wrongly assigned profit center by system. Now i have to debug from where this invalid profit center is coming while creating payment proposal for F110.

Now Since F110 executes background job to create proposal i cant debug the code. More over i tried to run program in foreground although its not allowing me due to it was not executed from f110. I tried JDBG to debug background job but even it did not workout. Can someone can flash some light on this. Thanks!!!!!!
