Edit Opening Balance AR Invoice

Hello @sc-cf,

You can only add a class to your opening balance entry as a whole transaction. This can be selected from the CLASS filed of your invoice.

But if you wish to edit the line item, you'll be prompted with an error that you're unable to edit it. Instead, you'll want to delete it and manually create each invoice to add a class.

To do so, you can delete your opening balance entry by opening it and click the Delete button. Once completed, you can go ahead and manually create each invoice.

I've got you our Income and Expense articles in case you need some ideas about handling your customer transactions.

Let me know in the comment section down below if you have any other concerns, @sc-cf. I'll be always around ready to help.

I'm having the same issue.  I am changing the CLASS at the top of the invoice entry screen, not on individual lines.  I'm getting the Warning:  you cannot add or edit a line item on an opening balance transaction.

I don't want to have to delete and re-enter the invoice.  

Hello there, @cajunsfan49.

Classes are used in separating transactions that relate to different departments or types of business. If you cannot change the class in the invoice, I advise using verify and rebuild data. This is commonly used when having an error while using QuickBooks Desktop. Please create a backup copy first of your company file before performing the steps.

Here’s how.

1. Choose Window then, Close All.
2. Verify Data. Choose File then Utilities. Select Verify Data. 
3. Choose File, Utilities then, Rebuild Data.
4. Select where you want to save your backup, then select OK.
5. The Rebuild Data utility starts as soon as the backup is finished.
6. Click OK when you get the message "Rebuild has completed".

If the issue persists, I suggest deleting the transaction or invoice and recreate again.
