Hi,
I'm trying to work out how these custom entries for a source of data in payment files work --- a quick Google tells me that it's something to do with the below enhancement option, but I can't work out what I'm meant to do. Effectively the customer wants to take an extension field from a customer account and map that to a field in a payment file, and it seems like there are some customisable fields provided by SAP. Does anyone know how they work? I tried just writing a simple value to one of them in the hopes it would do something (see below) but I didn't have any luck.

Thanks,
Lewis
