Fishbowl: "Unable to change the standard cost" — receive reconciled PO items first
Unable to change the standard cost at this time. Receive all Reconciled, but not Received, purchase order items for this part first.
What triggers it
This part is on one or more purchase orders where the received items have been reconciled (the cost matched and confirmed against the vendor bill) but the goods have not been fully received into inventory yet. That leaves the incoming quantity in a settled-cost, not-yet-on-hand state. The message names the exact condition: there are items that are “Reconciled, but not Received,” and Fishbowl will not let you touch the standard cost until every such item for this part is received.
Why Fishbowl blocks it
The standard cost is the value each unit carries when it enters inventory. When a receipt has been reconciled, its cost is already locked to what you agreed to pay. If you changed the standard cost while that receipt was still pending, the inventory would come in at a cost that disagrees with the amount already reconciled, creating a cost layer that no longer ties out. Fishbowl blocks the change so the pending inventory lands at the value it was reconciled at, keeping the on-hand valuation and the vendor-side numbers in agreement.
What to do
Receive the reconciled PO items for this part first. Open the purchase orders showing this part, complete the receipt for the items already reconciled, and let their cost settle into on-hand inventory. With nothing left in the reconciled-but-not-received gap, return to the part and change the standard cost. This is a sequencing correction, not an undo: you are letting the committed cost finish posting before you move the value going forward.
If it is already reconciled or exported
Reconciled cost has effectively been promised to your accounting system, so do not try to force the cost change by voiding or unreconciling the receipt to clear the block. That unwinds a cost already matched to a vendor bill and can leave your inventory valuation out of step with your general ledger. Receive the items, confirm the on-hand value posted as expected, and only then adjust the standard cost so both sides stay reconciled.
