Purchase Order Invoice Reversal in AX 2012
There are couple ways of reversing the PO Invoice in AX 2009 and prior versions. However, there is a procedure that can’t be done in AX 2012. Reversing PO Invoice in AX 2009 can be done by directly entering minus quantity in “Receive now” field at the PO line that wanted to be reversed. Then proceed by posting a delivery note and invoice subsequently. This will reverse the delivery note/invoice on that positive PO line. This procedure, though has a tidy result, is no longer allowed in AX2012. User has to create separate negative PO line to do the reversal of the PO Invoice. User will get following message because both receive now and ordered quantity must have the same sign (either positive or negative). The procedure is well explained by Microsoft in following link https://technet.microsoft.com/en-us/library/hh454990.aspx
