Single Payment to be done for a supplier with invoices in multiple OUs from one common bank

We are currently using Oracle 12.1.3 version. We have one ledger with multiple OUs.  We are planning to do payments to vendors using a single bank with invoices in multiple OUs for a vendor. Eventually the vendor should get one cheque/epayment for the invoices which are booked in multiple OUs.

With the help of Oracle Doc ID 1543159.1 following setup was done In test instance :-

[1] Payment responsibility to have MOAC (multi org access control) for all the OUs from where invoice is entered &

[2] To add all the organizations in the single bank account from where payments will be disbursed.

Was able to make payment to a single vendor/site for invoices of multiple OUs but system created different document numbers for diff invoices (OU wise) instead of one single document number.
