Hi there, premiershield2023.

I'll make sure you'll be able to access the Where Used (in Assemblies)function in QuickBooks Desktop (QBDT).

You'll have to make sure the Advanced Intory Settings are turned on from the List menu. This way, you'll see the Where Used (in Assemblies) function. 

Here's how:

1. Go to the List at the top menu bar. 

2. Select Items & Inventory from the left menu. 

3. Click on the Company Preference tab. 

4. Select Advanced Inventory Settings. 

I've additionally included a few detailed resources about working with inventory assemblies that may come in handy moving forward:

• Track the products you manufacture
• Set up a bill of materials
• Combine inventory items to build finished goods

Keep your post coming if you need more help with inventory assemblies. Have a great day!
