Overview

This Quick Reference Guide (QRG) is part of a series of guides that show you how to respond to alerts you may see in the right-hand side panel of an invoice you are viewing in the eMaryland Marketplace Advantage (eMMA).

In eMMA, a blocking alert ( ) indicates that action must always be taken before the approval process can move forward. A non-blocking alert ( ) indicates that action must be taken before the approval process is complete but that the approval process may move forward in some situations. In this situation, the system is designed to prevent duplicate invoice payment and will not let the process move forward.

This QRG shows the steps to take if the following alert appears: “Invoice number already exists”

NOTE: For best results, use the Google Chrome browser to access eMMA.

If you need help at any time, please reach out to the eMMA helpdesk at emma.helpdesk@maryland.gov. 

What It Means

This alert means that the voucher you are viewing contains a Vendor Invoice Number that matches one or more vouchers already in eMMA. This may have resulted after an eMMA user began creating a new voucher unaware that a voucher for the same payment already existed.

1. Access eMMA at https://emma.maryland.gov and log in with your credentials.
   
   NOTE: Depending on your agency, you may only need to click the State SSO Login (Secure Auth) button or the MDOT SSO Login (MSAzure) button and log in with your credentials.
   
    
2. Click the Vouchers tab and select the Browse Vouchers option from the drop-down menu.
   
   
   
3. Enter the VENDOR’S INVOICE NUMBER (not the INV number) in the Keywords field and click the Search button.
   
   
4. Review the status of each invoice located under the Status column to the right.
   
   PRO TIP: Click the Edit (pencil) icon on the left to view more invoice details.
   
   
5. Determine next steps; Reach out to helpdesk or ask your financial manager what needs to happen.
