• What is the cause and solution for SAP error message /IWFND/CM_MGW120 - Co-deployment is not supported ?

  The SAP error message /IWFND/CM_MGW120 Co-deployment is not supported typically occurs in the context of SAP Gateway and OData services when there is an issue with the deployment of the service in a co-deployment scenario. This error indicates that the system is unable to support the co-deployment of the SAP Gateway and the backend system.
  Cause:
  
  
  Co-deployment Configuration: The error often arises when the SAP Gateway and the backend system (like an SAP S/4HANA system) are not properly configured for co-deployment. This can happen if the systems are not aligned in terms of versions or if the necessary configurations are missing.
  
  
  Version Mismatch: If the SAP Gateway and the backend system are running on different versions that do not support co-deployment, this error can occur.
  
  
  Service Activation Issues: The OData service may not be activated correctly in the backend system, or there may be issues with the service registration.
  
  
  Network Issues: Sometimes, network connectivity issues between the SAP Gateway and the backend system can lead to this error.
  
  
  Solution:
  
  
  Check Configuration: Ensure that the SAP Gateway and the backend system are correctly configured for co-deployment. This includes checking the system landscape and ensuring that both systems are compatible.
  
  
  Version Compatibility: Verify that both the SAP Gateway and the backend system are on compatible versions. You may need to upgrade one of the systems if they are not compatible.
  
  
  Service Activation: Go to the SAP Gateway system and check if the OData service is activated. You can do this using transaction code /IWFND/MAINT_SERVICE. Ensure that the service is listed and activated.
  
  
  Check System Alias: Ensure that the system alias used in the Gateway is correctly pointing to the backend system. You can check this in transaction code /IWFND/MAINT_SERVICE under the "System Aliases" tab.
  
  
  Network Connectivity: Check the network connectivity between the SAP Gateway and the backend system. Ensure that there are no firewall or routing issues that could be causing communication problems.
  
  
  Review Logs: Check the SAP Gateway logs for more detailed error messages. You can use transaction code /IWFND/ERROR_LOG to view the error logs and get more context on the issue.
