Overview

You may notice that the Invoice Group column in Outstanding Invoice Report is empty even though you had set up an invoice group and linked it when setting up the registration in catalog admin. 

Solution

The Invoice Group column in the Outstanding Invoice Report is populated only when Batch Invoicing has been used to create the invoice. In order for the Invoice Group to be populated, use Batch Invoice to create invoices.

Batch Invoicing is located under Reports > Activities.
