Important: Deleting a build transaction removes it completely from QuickBooks, leaving no record that the transaction ever existed. If you want to retain the transaction history for this assembly, adjust the quantity on hand for components and assembly items rather than deleting the build transaction.
To do this task
Open the assembly build transaction.
Go to the Edit menu and click Delete Build.
Click OK to confirm the deletion.
What happens when I delete an assembly build transaction?
All component inventory parts and subassemblies on the Bill of Materials are returned to inventory, and the quantity of the assembly item in inventory is reduced. However, if the build transaction you delete is pending, the deletion does not affect the quantity on hand of components and assembly items.
