this is not a bug. In the older veriions of RPRO if this happens due to corruption etc. in reconstruct there was a rebuild recieved QTY feature which would go back into former vouchers and reapply the quantities to the PO. in 8 series this feature has been removed from reconstruct and is now in DVS under maintenance>recalc>rebuild PO QTY
Please dont use the “B” word (bug) untill you are 100% sure it is a bug. becasue once you let that slip that you think it is a bug they have in mind it is a bug when someone else may find out it isnt a bug. because clients dont pay for bugs lets not get their hopes up and then hit them with a bill once we say its not a bug.
