Hi there, @AdeleB.

Welcome and thanks for joining us here in the Community. I'm here to help get this taken care of, but I have some questions about your concern first.

In order for me to provide you with the best information, can you please clarify what you mean about PO number from the invoice? Did you add a custom field on the invoice for the PO number?

You can leave a comment below to add more details. This additional information will help to ensure that I deliver you the best solution.

I look forward to your response. Wishing you well.
