Item Record Displays an Average Cost Even if There Are No Related Transactions yet

This could happen when users enter an item receipt, a positive inventory adjustment or a stand-alone bill for the item and then delete it afterwards. The field retains the average cost value just like with "Store Value" fields.

Users do not have to worry about this because soon as you enter an inventory affecting transaction, this will be corrected by itself.

The alternate solution in Enhancement 227653 also suggest the steps below:

1. Transactions > Inventory > Adjust Inventory Worksheet.
2. Select the Adjustment Account.
3. Select Location.
4. On the New Qty, enter 0.
5. On the New Value, enter 0.00.
6. Save.
