Change cost information for a part or assembly

Article • 4/27/2026 • 2 min read

When the cost of a part or assembly changes, record the change in the item master.

If the costs for many items change, roll up the costs instead of changing them one by one.

When you change the cost of a part or assembly in the item master, you create postings to the general ledger. If you reduce the cost of an item, you debit the Product Class Material Variance account and credit the Product Class Inventory account. If you increase the cost of an item, you debit the Product Class Inventory account and credit the Product Class Material Variance account.

To view costs transferred to the general ledger, print the Order Cost Data Trans to GL report before and after you change costs for a part or assembly.
