How to record Payments made on your behalf in AP?

Hi,

The context is that the client -Company A is owned by another entity Company B.

Company A has EBS Financials and AP is setup.

Company B is not setup on EBS. Currently Company A writes to Company B to pay some of their AP Supplier Invoices for them as Company A is in financial difficulties.

The Supplier Invoices are recorded in Company A's books [POs were generated by Company A] but the Invoices were paid by Company B's back account of which Company A has no ownership.

How can the payments be recorded in Company A's Payables module other than by creating a 'dummy' bank account to record the payment?
