• What is the cause and solution for SAP error message /IWBEP/CM_MGW_RT090 - Property conversion not allowed because model is set to "no conversions" ?

  The SAP error message /IWBEP/CM_MGW_RT090 indicates that there is an issue with property conversion in the context of an OData service. This error typically arises when the OData model is configured to disallow conversions for certain properties, and an attempt is made to convert a value that is not permitted.
  Cause:
  
  Model Configuration: The OData model is set to "no conversions" for certain properties. This means that the model does not allow automatic type conversions for these properties.
  Data Type Mismatch: The data being sent or received does not match the expected data type defined in the OData service. For example, if a property is defined as an integer in the model but a string is being sent, this can trigger the error.
  Incorrect Mapping: There may be an issue with how the properties are mapped in the OData service, leading to a mismatch between the expected and actual data types.
  
  Solution:
  
  Check Model Configuration: Review the OData model configuration to ensure that the properties that require conversion are set to allow conversions. This can typically be done in the service definition or metadata.
  Data Type Validation: Ensure that the data being sent to or received from the OData service matches the expected data types. Validate the input data before making the OData call.
  Adjust Property Definitions: If necessary, adjust the property definitions in the OData service to allow for conversions or to match the data types being used in the application.
  Debugging: Use debugging tools to trace the OData service calls and identify where the conversion is failing. This can help pinpoint the exact property causing the issue.
  Consult Documentation: Refer to the SAP documentation for OData services and the specific error message for additional context and troubleshooting steps.
