You mean the PO field? Yes, go to screen designer and make it a required field.
Conditionally required? Yes this is doable with VBA, you'll need to define the conditions.
in general terms, on the macform_close() event (or perhaps a different event, I'd have to research it) you test test your conditions and if the oe_po_no is blank. If so disallow the save of the order, send up a message box that the PO is required, ad set the focus to the PO field.
The details kind of go beyond the scope of this forum. If this is something you are not comfortable with, you should contact your Macola reseller or Exact regional office.
It might be easier just to make the PO field a required field 100% of the time, which only takes 10 minutes.
