This error indicates that there is a mismatch between the ABAP data type defined in your ABAP program and the corresponding OData Entity Data Model (EDM) core type.
Cause: Type Mismatch: The ABAP type you are using in your data model does not have a corresponding EDM type. For example, if you are using a complex ABAP type or a type that is not supported by the OData service, this error will occur. Unsupported Data Types: Certain ABAP data types (like STRING, XSTRING, or custom types) may not have a direct mapping to the EDM types. Incorrect Mapping: The mapping between ABAP types and EDM types may not be correctly defined in the service implementation.
Solution: Check Data Types: Review the ABAP data types used in your OData service implementation.
