Ipad Production app for OBeer frequently won't process pdo's if inventory is less than or rounding up from 0.000 . E.g. If the pdo tries to use all of a hop lot inventory of lot A that SAPBuis1 says is 0.009 lbs, Ipad app has error that it attempts to issue 0.01 lbs, of which there is not enough inventory to support that. So it gives an insufficient qty error, that not easily correctable in the ipad production app. I just think the two systems should agree on how many significant figures to use.
