Why are purchase orders with negative values not matching goods received notes?

This article covers purchase order lines with negative values failing to match a goods received note (GRN). Whether this happens depends on the purchase order's matching method, matching by amount does not support negative values, matching by quantity does.

How matching method affects negative values

How iplicit handles a negative value depends on the purchase order's matching method:

• Matching by quantity — negative amounts can be submitted and matched normally
• Matching by amount — negative values cannot be matched.

Check the matching method on the purchase order's settings to confirm which applies to your configuration.

How to fix a purchase order with unmatched negative lines

If the purchase order is matched by amount:

1. Open the affected purchase order
2. Remove the negative lines
3. Save the purchase order
4. Re-run the matching process.

The remaining lines then match as expected.

If the purchase order is matched by quantity, no action is needed, negative values match normally.
