# Fishbowl: "Set last cost to zero?"

> Confirmation warning when attempting to set a part's last cost to zero.

## What it means

You're setting the last cost entry for this part to zero. Fishbowl flags this as unusual because parts typically carry a cost value. This action may impact inventory valuation, cost tracking, or any pricing tied to part cost.

## What to check

- Verify you're editing the correct part and that zero is the intended cost
- Confirm this part should actually have zero cost (e.g., free material, rework, or non-inventory item)
- If this is an active part, check how your inventory costing method (weighted average, FIFO) will handle zero cost
- If this was accidental, cancel the dialog and verify the cost value you meant to enter
