  Shorten Names: If possible, modify the names of the ranges or parameters in the OData service to be shorter. This may involve changing the way the service is designed or how it handles input.
  Check Service Implementation: Review the implementation of the OData service to ensure that it is not generating unnecessarily long names. This may involve looking at the code in the service or the way it constructs queries.
  Adjust Data Model: If the issue is related to the data model, consider redesigning it to reduce complexity and avoid long names.
