AP Draft account adding to g/l Bank Accounts

Hi

In JD Edwards EnterpriseOne  9.1 Edition while adding the AP Draft account to G/L Bank Accounts the system gives me an error message,

I want the system to pick the payment number from the draft a/c which is specified in the g/l bank accounts when ever I perform Drafts payment with voucher match.

Please make me clear that if I perform the automatic payment processing, if I specify the g/l bank account as drafts payable account in Speed status change program for all the vouchers to be paid then do I need to specify the drafts payable account in this g/l bank accounts application or not.
