Hi, Mavis,

The way we enter the primary vendor is not on the header tab. We've found that it's best to enter the vendor on the line detail record. This provides flexibility, as items on a single PO are not always coming from the same vendor. As well, the vendor selected on the first line detail item will automatically carry forward to the next detail on the PO until you change it (which is very useful when the primary vendor is the same for all items).

So far, I haven't been able to recreate the problem you report in 8.1A.

I'm curious, are you and your co-worker running PO from the same place (i.e. from the server? or are you each running the program locally, standalone?).
