Lockbox User Exit Selection Fields and Matching Open Items in CustomerAccts

113 Views

Dear SAP Gurus,

I have an issue with lockbox process. The problem is selecting the customer open item for clearing. Our Client uses standard SAP USER EXIT (FEBLB001).

Our billing document number does not equal to the financial accounting document number all the time. We store our billing document number in the Assignment field some times, and so this is the number the customer will reference when remitting payment. I have not been able to find a way to make the SAP system to use the customer's reference number (e.g. Assignment field) to clear the open item.

I m not sure how to resolve this issue. As far as my knowledge, we have to add selection field ZUONR to USER EXIT apart from XBLNR, BELNR. Please help me with this problem by providing me some basic knowledge. I would greatly appreciate for help.

Thanks
