multiple prepayment activities in one operating unit

Hello everyone.

We have only one OU, however, we have a requirement to be able to account for Oracle prepayments to multiple business units (first segment of the GL account) based on the order/invoice type.

I know that per Oracle standard functionality in a single OU we can have only one active prepayment receivable activity, so it will have to have only one designated business unit per that activity.

But are we the only ones facing such requirement? Did anyone else encounter anything similar and how did you go about it?

Or should we just pick one home office BU and have all prepayments go there since we are in a single OU?
