FLB1- Lockbox Postprocessing

Hello Folks-

I urgently need some insight here. I am testing the lockbox functionality and for all payments that are unprocessed, it is simple enough to double click on the item and search for a customer account. However, it doesn't work when I want to assign the payment to a G/L account?!?

I change the account type from a d "customer" to an s "general ledger" and once I input a general ledger number, I get an error message stating that there is no payment advice in that company code????

What does this mean? Why can't I post to a G/L? Any ideas?

POINTS PROMISED!!!!
