The simple answer is no you cannot have a Vendor setup to do both Online Ordering and have running Purchase Orders (PO).
Online ordering indicates that you want the parts now, which generates an automatic PO. Whereas, a running PO indicates that you want to order the parts later, after the PO is closed out, by selecting the PLACE ORDER button on the PO.
The work around is to create two vendors:
- Setup one Vendor for online ordering
- Setup another Vendor for running POs. (Check the Running PO Vendor box in Vendor Maintenance.)
