ACC have changed the claim number and my payments won't automatch
ACC often give a new claim number and then find an older claim number in the system.
If you already have earlier billing associated with the first claim number you were given, and the claim number you are now to use is associated with a new PO, ADD CLAIM NUMBER, then add the new PO to that.
If the claim number is related to billing already in the system and earlier POs will not be affected, you can edit and replace the claim number.
If you need to change the claim number associated with a particular PO that already has billing against it, edit the PO and paste the "new" claim in, then re-run the automatch.
