R03B575GB - Error: No Records found in F0401 Supplier Master Table for this Customer address number"

Hi,

I get the following error on the Auto Debit statements R03B575GB for direct debits for customers:

Error: No Records found in F0401 Supplier Master Table for this Customer address number"

I have found by entering a GL offset in the Supplier Master it clears this error and the transaction details are printed.

Could someone please explain why I need a bit of supplier data for a customer record?

Thanks

Adam
