Purchase Order Item is not matched to Invoice Item in Central Invoice Management

Dear all,

i recognize from note 3540020 that it is imaginable to lucifer a invoice against a acquisition bid successful Central Invoice Management (even if determination is nary PO fig connected the invoice), if the description, quantity, portion terms & currency matches. However erstwhile one tried it retired the strategy does not prime a acquisition bid but tries to publication it without a PO assignment. 

Here is the acquisition bid enactment item:

And present is the invoice:

I person activated the enhanced invocie point matching:

But the strategy inactive does not delegate the Purchas Order to the Invoice.

Does anyone person immoderate ideas arsenic to wherefore this mightiness be?

Thanks and champion regards
