• What is the cause and solution for SAP error message /IWBEP/CM_CP404 - Delta Link Keep Days ?

  The SAP error message /IWBEP/CM_CP404 Delta Link Keep Days typically relates to issues with the configuration of the delta link in the SAP Gateway or OData services. This error can occur when the delta link settings are not properly configured, particularly the "Keep Days" parameter, which determines how long delta link data is retained.
  Cause:
  
  Configuration Issue: The "Keep Days" parameter for the delta link might be set to a value that is not valid or is too low, leading to the error.
  Data Retention Policy: The system may be trying to access delta data that has already been purged based on the configured retention policy.
  System Settings: There may be inconsistencies in the system settings or missing configurations related to the OData service or the underlying data model.
  
  Solution:
  
  
  Check Delta Link Configuration:
  
  Go to the transaction code /IWFND/MAINT_SERVICE to check the OData service configuration.
  Ensure that the "Keep Days" parameter is set to a reasonable value that allows for sufficient data retention.
  
  
  
  Adjust Keep Days:
  
  If the "Keep Days" is set too low, increase it to a higher value (e.g., 30 days or more) to ensure that the delta data is retained long enough for processing.
  
  
  
  Review Data Purging:
  
  Check if there are any background jobs or processes that might be purging delta data prematurely. Adjust these settings if necessary.
  
  
  
  Monitor Delta Link Usage:
  
  Monitor the usage of the delta link to ensure that it is functioning as expected and that data is being retained according to the configured settings.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific version of SAP Gateway you are using for any additional configuration steps or best practices.
