• What is the cause and solution for SAP error message /IWBEP/CM_MGW_RT171 - XSD ABAP data types are not supported ?

  The SAP error message /IWBEP/CM_MGW_RT171 XSD ABAP data types are not supported typically occurs in the context of SAP Gateway and OData services when there is an issue with the data types defined in the ABAP structure or data model that are not compatible with the XSD (XML Schema Definition) used in OData services.
  Cause:
  
  
  Unsupported Data Types: The error is primarily caused by the use of ABAP data types that are not supported in the context of OData services. Common unsupported types include:
  
  Complex types (like nested structures)
  Certain numeric types (like p or dec with specific precision)
  Non-standard types or custom types that do not have a direct mapping in OData.
  
  
  
  Incompatible Structures: If the structure or entity type defined in the OData service contains fields with unsupported data types, this error will be triggered.
  
  
  Model Definition Issues: If the data model defined in the service does not adhere to the expected standards for OData, it can lead to this error.
  
  
  Solution:
  
  
  Review Data Types: Check the ABAP structure or data model used in the OData service. Replace unsupported data types with compatible ones. For example:
  
  Use string instead of complex types.
  Use int or float instead of p or dec.
  
  
  
  Modify the OData Model: If you are using a custom OData model, ensure that the data types defined in the model are compatible with the OData standards. You may need to adjust the model definition accordingly.
  
  
  Use Standard Types: Whenever possible, use standard ABAP data types that have a direct mapping to OData types. For example:
  
  CHAR to string
  INT to int
  FLOAT to float
  
  
  
  Regenerate the Service: After making changes to the data types, regenerate the OData service and check if the error persists.
  
  
  Check for Nested Structures: If your data model includes nested structures, consider flattening them or using simpler types that can be easily represented in OData.
