How to set up Three Way Match Vendor Bills?

Hi There

I have enabled the 3 way vendor bill match for testing without any adjustments to the workflow.

There has been one vendor quantity difference value set up

The resulting bill was auto approved.

1 Is the quantity discrepancy on the vendor record (1 in this example) suggesting that any quantity that is billed over and above the purchase order original ordered quantity will be flagged for approval routing? e.g. if a quantity of 6 was billed when the original PO had quantity of 5

2. Do the tolerance and quantity difference levels need to be set on each vendor record? Can they be set at a company wide level? (with any differences to the blanket company wide level being set on the individual vendor records)? .e.g A company wide rule is set that any quantity difference of 2 will result in the approval routing being triggered. Though for one particular vendor, the approval routing will only be triggered if the quantity variance exceeds 5
