How can I update an expired certificate for a connection in the Managed Gateway for the Spend & Network portal?

1. Login to the Managed Gateway for Spend&Network portal using the lite admin account (This is for Ariba Support). Supplier/Buyers will login with their regular Managed Gateway for Spend&Network admin user account by navigating from SAP Business Network admin area.
2. Once you login, you will see the expired certificates like below:

3. Click Update Certificates button so that it will take you to the project connections screen:

4. Click on the edit symbol on the corresponding connection. If you are unaware which certificate or connection you need to edit. Go to the Certificates page where you can see the Connection name and the certificate expiry date.

5. Click on the Box in Authentication Certificate and paste the certificate content. Click OK to continue. This certificate is basically used for authentication.

If an certificates is expired, Managed Gateway for Spend&Network will not send transactions to the system configured in the project. Currently there is no automated notification sent to buyers/supplier before the certificate expiration date. Buyer's/Supplier's need to login to Managed Gateway for Spend&Network portal manually to know this. Also the old certificate cannot be deleted from the Managed Gateway for Spend&Network portal so anytime when you have the expired certificate in the Managed Gateway for Spend&Network keystore, you will see the pop up when you login to Managed Gateway for Spend&Network.
