I'll share some details in the Purchase Date column, jack771. This way, I can guide you accordingly. 

I'll ensure you'll know when the Purchase Date shows in the Item Listing and Inventory reports in QuickBooks Desktop. 

The Purchase Date column in the reports will not be blank if your Purchase Order created has a specific line on that detail. See the sample screenshots below for your reference: 

If you want to add this column so that the reports are not blank, follow these steps:

1. Go to the Vendors menu and pick Create Purchase Orders. 
2. Select Formatting and choose Customize Data Layout. 
3. Click Columns and type Purchase Date in the empty field.
4. Check the Screen, Print, and Order boxes so they will be visible in the forms and reports. 
5. Hit OK. 

However, if you don't need it in your reports, you can uncheck the column by customizing it.
