You may need to modify a Purchase Order that already has [cost allocation](https://help.getedara.com/en/articles/5244186-allowing-cost-allocation-in-purchase-order) applied to update stock items, quantities, or other information. Since the allocated costs are linked to the Purchase Order data, you must first disable cost allocation, make the required changes, and then enable it.
