We have a vendor invoice workflow set up which looks for a 3 way match on any PO Invoice - if that is true then the invoice posts, if it's not true then it goes for approval. Our Tax Invoice Validation options are set for "Post tax invoice with discrepancies" = "Allow with warning"
The problem I have is that when it goes for exception approval and the reason behind the lack of match is due to quantities not matching then the workflow fails and does not post the invoice.
The only way I was able to get around this was to set the individual PO line to allow over-delivery and then receipt up to the value of the invoice. As we are using Procurement Categories this is not an ideal solution since an over-delivery percentage can't be set per category and would have to be entered on an individual line basis.
Is there another way we get the outcome we are trying to achieve? i.e. setting up the POs differently.
Thanks
