  The SAP error message /IWBEP/CM_MGW_BOP_DT015 Internal data type not supported: &1 typically occurs in the context of SAP Gateway and OData services. This error indicates that the system encountered an internal data type that is not supported when processing a request or response in an OData service.
  Cause:
  
  Unsupported Data Type: The error is primarily caused by the use of a data type in the ABAP backend that is not recognized or supported by the OData service. This can happen if the data type is custom or if it is a complex type that the OData framework does not know how to handle.

  Check Data Types: Review the data types used in the ABAP backend. Ensure that they are compatible with OData. Common supported types include basic types like CHAR, STRING, INT, DEC, etc.
  Modify OData Model: If you are using custom types, consider modifying the OData model to either remove or replace unsupported types with compatible ones.
  Update Service: If the OData service is generated from a data model, regenerate the service to ensure that it reflects the current state of the underlying data structures.
  Debugging: Use transaction /IWFND/ERROR_LOG to check for additional details about the error. This can provide insights into what specific data type is causing the issue.
  Check Annotations: Ensure that the annotations in the OData service are correctly defined, as they can affect how data types are interpreted.
  Consult Documentation: Refer to SAP documentation for the specific version you are using to understand the supported data types and any limitations.
