Is it normal to see Purchase orders on the Deferred Expense Waterfall Summary?

no, PO is not posting transaction…. odd. how can you get a waterfall

i know but the user create bill with amortization schedule from Po

VB is a posting transaction. It really does not matter if it is a stand alone bill or created for PO bill

I agree with you, but the PO only appears when the bill is created from an PO so I don't know why. If I exclude PO from my report, the balances are not correct.
