This error indicates that a precision value has been specified for a primitive type that does not support it.
  Cause:
  
  Incorrect Data Type Definition: The error usually arises when a primitive type (like Edm.String, Edm.Int32, etc.) is defined with a precision or scale that is not applicable. For example, you might be trying to define a string with a precision, which is not valid.
  OData Service Configuration: The OData service might be incorrectly configured, leading to the generation of metadata that includes invalid definitions.
  Model Annotations: If you are using annotations in your data model, they might be incorrectly specifying precision for types that do not support it.
  
  Solution:
  
  Check Data Model: Review the data model definitions in your ABAP code or the relevant CDS views. Ensure that primitive types are defined correctly without unnecessary precision or scale.
  Adjust Metadata: If you are using annotations, ensure that they are appropriate for the data types you are working with. Remove any precision or scale specifications from primitive types that do not support them.
  Regenerate OData Service: After making changes to the data model, regenerate the OData service to ensure that the metadata is updated correctly.
  Test the Service: After making the necessary adjustments, test the OData service again to see if the error persists.
  
  Related Information:
  
  Primitive Types in OData: Familiarize yourself with the OData specification regarding primitive types and their properties. Not all types support precision and scale.
  SAP Notes: Check SAP Notes for any known issues or updates related to OData services and metadata generation.
  Debugging: If the issue persists, consider debugging the OData service to trace where the incorrect precision is being set.
  
  By following these steps, you should be able to resolve the error and ensure that your OData service functions correctly.
