• What is the cause and solution for SAP error message /IWBEP/CM_MGW_RT179 - Uppercase setting is not allowed for property &1 ?

  The SAP error message /IWBEP/CM_MGW_RT179 indicates that there is an issue with the uppercase setting for a property in an OData service. This error typically arises when the OData service is trying to process a property that is defined with an uppercase setting, which is not allowed according to the OData specifications.
  Cause:
  
  Uppercase Property Name: The property name in the OData model is defined in uppercase, which is not compliant with the OData standard that requires property names to be in camelCase or lowercase.
  Model Definition: The issue may stem from the way the data model is defined in the ABAP backend or the way the metadata is generated for the OData service.
  Service Implementation: If the service implementation is trying to access or manipulate properties that are defined in uppercase, it can lead to this error.
  
  Solution:
  
  Check Property Names: Review the property names in your OData model and ensure that they are defined in camelCase or lowercase. For example, instead of PROPERTYNAME, use propertyName.
  Adjust Metadata: If you have control over the metadata generation, ensure that the property names are generated correctly. You may need to adjust the annotations or the way the model is defined in the ABAP backend.
  Regenerate the Service: After making changes to the property names, regenerate the OData service to ensure that the changes are reflected in the service metadata.
  Test the Service: After making the necessary changes, test the OData service to ensure that the error no longer occurs.
  
  Related Information:
  
  OData Standards: Familiarize yourself with the OData specifications, particularly regarding naming conventions for properties.
  SAP Gateway: If you are using SAP Gateway, check the configuration and implementation of your OData service in the SAP Gateway Service Builder (transaction code SEGW).
  Debugging: Use debugging tools to trace the execution of the OData service and identify where the uppercase property is being referenced.
  
  By following these steps, you should be able to resolve the error message /IWBEP/CM_MGW_RT179 and ensure that your OData service complies with the required standards.
