PO BPM Blank Title 93797

PO.Update

field is unit cost

this will ensure each line has a price entered, also I created a check box on PO line tab in case a price needed to be entered as 0.00.

so the code reads like:

PODetail.CheckBox() = FALSE AND PODetail.UnitCost = 0
raise exception blah blah...
Has anyone created a BPM to keep a user from entering $0.00 for the unit cost of a PO? If so, what method did you use and what rules?

Thanks,
Greg
