I keep getting this message. You can’t create or modify a transaction with a date that comes before you started tracking quantity on hand for the following: 1R4-00058D.

Hi there, SeaIndustries. I know why you're getting this prompt when modifying your Purchase Order in QuickBooks Online (QBO).

The warning "You can’t create or modify a transaction with a date that comes before you started tracking quantity on hand for the following: 1R4-00058D" will appear if the transaction date you're trying to create is prior to the "As of" date of the inventory item. Kindly ensure that the transaction date matches the date when you started tracking the Quantity on hand of this item.

To verify the date, you can refer to these steps:

1. Go to the Gear icon, then Products and Services.
2. Locate the item used in the transaction.
3. Click Edit in the far right.
4. Go to the Quantity on hand section, and click the blued highlighted word Starting Value.
5. When a prompt appears, click Got it!.
6. Confirm the As of date in the Inventory Starting Value #START page.
7. You can configure it. However, if you don't want to leave it as it is, then click Save and close.
