• What is the cause and solution for SAP error message /IWBEP/CM_MGW_RT172 - XSD ABAP data types are not supported; check property '&1' ?

  The SAP error message /IWBEP/CM_MGW_RT172 indicates that there is an issue with the ABAP data types being used in your OData service. Specifically, it suggests that the XSD (XML Schema Definition) data types that are being generated or used in the context of the OData service are not supported. This can occur when the data types in your ABAP code do not map correctly to the expected XSD types.
  Cause
  The error can be caused by several factors:
  
  Unsupported Data Types: The ABAP data types used in your service might not have a corresponding XSD type. For example, certain complex types or custom types may not be supported.
  Incorrect Annotations: If the annotations in your ABAP code are not correctly defined, it can lead to issues in type mapping.
  Incompatible Structures: If you are using structures or tables that contain unsupported data types (like certain nested structures or specific ABAP types), this can trigger the error.
  Version Issues: Sometimes, the version of the SAP system or the OData service implementation may not support certain data types.
  
  Solution
  To resolve this error, you can take the following steps:
  
  
  Check Data Types: Review the ABAP data types used in your OData service. Ensure that they are compatible with the XSD types. Commonly supported types include:
  
  Simple types like STRING, INT, DECIMAL, etc.
  Avoid using complex or custom types that do not have a direct mapping.
  
  
  
  Modify Annotations: If you are using annotations in your ABAP code, ensure they are correctly defined and that they correspond to the expected data types.
  
  
  Use Supported Structures: If you are using structures or tables, ensure that they only contain supported data types. You may need to refactor your data model to use simpler types.
  
  
  Check OData Service Implementation: Review the implementation of your OData service. Ensure that the service is correctly defined and that the data types are properly mapped.
  
  
  Test with Different Data Types: If possible, try replacing the unsupported data types with supported ones and see if the error persists.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific version you are using to understand the supported data types and any limitations.
  
  
  Debugging: Use transaction codes like /IWFND/ERROR_LOG to check for additional error messages that might provide more context about the issue.
  
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide guidance on supported data types.

  SAP Gateway: Familiarize yourself with the SAP Gateway framework, as it plays a significant role in the creation and management of OData services.
  Data Type Mapping: Review the mapping of ABAP data types to XSD types to ensure compatibility.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
