Blanket/Framework Purchase Orders & MIRO
We are investigating the usage of Blanket Purchase orders for our contracts department and the users are quite happy with what they can do with this. As the PO could last up to 2 years for the length of a contract together with an unknown exact amount, details are placed in the "Limits" section for pricing. For example, for "skip hire", they might put 10000GBP in the "expected value" field and this becomes the PO price.
However when an invoice for the first hire comes in e.g. 100GBP, we process MIRO as we have always done but message M8534 comes up saying the balance is not zero and in this case it never will be most of the time. The price on the PO line detail shown is also shown as zero in MIRO.
I guess I;m missing something simple that needs to be set on the accounts side to handle this aspect of the Blanket PO but I cannot find exactly what this is so far.
Could someone please advise on how to get invoice verification handled over the period of a blanket PO such as this.
