If the Routing changed on the item, do you need to delete the IF and start again? we had a router that was totally off, we fixed that and the work order completion is correct but IF still displays old pricing.

IF as in inventory fulfillment? Are you worried about costing, and not pricing? If so, typically when you backdate a transaction (your WO completion which defines the costing), subsequent transactions (Fulfillment) will get caught up in the costing engine and updated when processed.

Ooo I didn’t try that let me try that but yes costing not pricing
