PO numbering method by facility

Would like to define PO numbering by FAC, wants to be able to Auto generate PO #'s in one Fac and use their own PO #'s in another.

Imported from [WISH-210] PO numbering method by facility.

We would like to utilize RTA to auto-generate next PO, but using different numbers per facility. Is there a way (existing) to do this? Currently, we issue a batch of sequential numbers to a couple of our facilities manually.
