Funny enough, the client just showed me a case (from March 2015) where the receipt date was used. Other than the timing, the circumstances are identical. I looked carefully and there is no other explanation.

So is there a setting somewhere that determines which date flows to Inventory - I have looked in PO Company Profile and didn't see it but maybe it's somewhere else. Or has something changed in the program since March 2015?

Doug - as I mentioned they would rather not change the vendor's invoice date. That would be an absolute last resort.

PS - I might add that they recently upgraded from PO 8.1D to PO 9.2B and IC 8.1E to 9.2A and these transactions were all entered using the older versions.
