Purchase order

Welcome to the community page of QuickBooks Online, @slm3423.

I'd gladly help you modify your purchase orders (PO) and provide information about closing dates in QuickBooks Desktop.

The warning message you're seeing is due to a feature in QuickBooks that protects the integrity of transactions from closed periods. As a result, any modifications that happen within or affect these closed periods need to be authenticated with a closing date password.

QuickBooks works based on the transaction date and not on the received date. Therefore, even if you received the items in June and the dated transaction is in May, it will affect a closed period since the purchase order was created in May.

You'll need to enter your Closing Date password to continue modifying this and to achieve your goal.

You'll also need to check your closing date and ensure it is correct. Here's how:

1. On the top menu, head to Edit and select Preferences.
2. Go to the Accounting section and choose Company Preferences.
3. Click the Set Date/Password button.
4. Set your correct closing date and password, then hit OK to save changes.
