Thank you for visiting the QuickBooks Community, saidrustamgtx-gm. Please keep in mind that the mobile app's features are limited. This is why searching for an SKU number in the app isn't currently unavailable. Let me provide an alternative step to achieve your goal.

1. Go to the Gear icon on the top menu.
2. Select Products and services.
3. Choose a product you'll want to enter the SKU
4. Click the Edit link. 
5. Enter the number on the SKU field with your desired format.
6. Click Save and close.

Once done, you can now pull up the mentioned report above. 

Here's how:

1. Go to Reports on the left side menu.
2. Enter the Product/Service List in the search field.
3. Tick the Gear icon on the report.
4. Place a checkmark on the SKU box.
