• What is the cause and solution for SAP error message /IWBEP/CM_CP079 - No count has been requested ?

  The SAP error message /IWBEP/CM_CP079 No count has been requested typically occurs in the context of OData services when a request is made to retrieve data, but the system does not have a count of the total number of records available for the requested data set. This can happen for several reasons, and understanding the cause can help in finding a solution.
  Cause:
  
  Count Parameter Not Set: The OData service may not have been configured to return a count of the total records. This can happen if the $count query option is not included in the request.
  Service Implementation: The OData service implementation may not support counting or may not have the necessary logic to handle count requests.
  Data Source Limitations: The underlying data source (like a database) may not support counting in the way the OData service is trying to implement it.
  Filter Conditions: If there are filters applied to the request, the service may not be able to determine the count based on the current implementation.
  
  Solution:
  
  Check the Request: Ensure that the request includes the $count parameter if you expect a count of the records. For example, the request URL should look something like this: .../EntitySet?$count=true.
  Service Configuration: Review the OData service configuration to ensure that it is set up to handle count requests. This may involve checking the service implementation in the backend (ABAP code) to ensure that it correctly processes count requests.
  Update Service Implementation: If the service does not currently support counting, you may need to modify the service implementation to include logic for counting records. This could involve adding a method to handle the $count request.
  Consult Documentation: Review the SAP documentation for the specific OData service you are using to understand its capabilities and limitations regarding counting records.
  Testing: After making changes, test the service again to ensure that the count is being returned as expected.
