You can change both pending and finalized inventory assembly builds.
What is an inventory assembly build?
To do this task
Go to the Reports menu, click Inventory, and then click Pending Builds.
Note: If you use Advanced Inventory, you also choose Reports > Inventory > Pending Builds by Site. You can track multiple inventory sites with the Advanced Inventory add-on which is only available in QuickBooks Enterprise Solutions (additional fees may apply). Learn more at www.qbes.com/inventory.
Print the Pending Builds report.
The status (pending or final) of an inventory assembly build is directly tied to the status of inventory on the specified build date. This is important to remember if you plan to increase the quantity of an existing assembly build. Increasing an assembly build quantity deducts more of that build's components from inventory, leaving fewer of those components available for other assembly builds with the same or a later build date. In some cases, this can cause a previously finalized assembly build to change to pending status. The only way you will know if a change you make to an assembly build causes other assembly builds to become pending is to run the Pending Builds report both before and after you change an existing build.
Find and open the inventory assembly build you want to change.
Make the necessary changes to the build information.
Click Build & Close to save your changes.
Run the Pending Builds report and print it again.
Compare this report to the first one you printed to see if your changes caused any other assembly builds to become pending.
If so, you'll need to wait until you have enough inventory and then mark those assembly builds as final again.
You'll need to check the build status periodically. Find and open the assembly build, and then see if the number displayed after "Maximum number you can build from the quantity on hand" is at least as much as the number in the Quantity to Build field.
