By Rose Gomez
In this guide, we'll learn how to process mixed returns in Gensco by referencing original invoice numbers and entering the details in Sage 100. We will cover how to search for the original invoice, copy the PO and invoice numbers, and handle entries with multiple PM numbers. This process helps ensure accurate record-keeping and proper handling of returns. Sage Paperless will not allow the same invoice number used twice. Sage 100 will warn you, but will allow it. It is important to reference the correct invoice number on all line items related to the credit memo.
