Upgrade Steps

Follow these steps to perform the upgrade:

In the Mule Palette view, click Search in Exchange.
In Add Dependencies to Project, enter sap s/4hana odata in the search field.
In Available modules, select SAP S/4HANA OData Connector and click Add.
Click Finish.
Verify that the mule-sap-s4hana-cloud-connector dependency version is updated to the version of the connector you are using in the pom.xml file in the Mule project.

Studio upgrades the connector automatically.

Post Upgrade Steps

After you install the latest version of the connector, verify the upgrade:

In Studio, verify that there are no errors in the Problems or Console views.
Verify that there are no problems in the project pom.xml file.
Test the connection and verify that the operations work.

Troubleshooting

If there are problems with caching the parameters and metadata, try restarting Studio.

Revert the Upgrade

If it is necessary to revert to the previous version of SAP S/4HANA OData Connector, change the mule-sap-s4hana-cloud-connector dependency version in the project’s pom.xml to the version to which you want to revert.
