  Cause
  The error is triggered when:
  
  A request is made to read data from an OData service without applying the necessary filters.
  The OData service is configured to require filters for certain entity sets to limit the amount of data returned or to ensure that only relevant data is accessed.
  
  Solution
  To resolve this error, you can take the following steps:
  
  
  Check the OData Service Configuration:
  
  Review the OData service definition in the SAP Gateway. Ensure that the entity set specified in the error message is configured correctly and that it requires filters for read access.
  
  
  
  Apply Filters in the Request:
  
  Modify the request to include the required filters. This can be done in the Fiori application by ensuring that the user interface allows for filtering options or by directly modifying the OData request URL to include the necessary query parameters.
  
  
  
  Review the Fiori Application Logic:
  
  If you are developing or customizing the Fiori application, ensure that the logic for fetching data from the OData service includes the necessary filters. This may involve updating the controller or model binding in the UI5 application.
  
  
  
  Check User Authorizations:
  
  Ensure that the user has the necessary authorizations to access the data. Sometimes, access restrictions can lead to similar errors.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific OData service you are using. It may provide insights into the required filters and how to structure your requests.
