• What is the cause and solution for SAP error message ESH_CHECK_CONN095 - Another CDS-activation is running. No Consist.Check possible. Try later. ?

  The SAP error message ESH_CHECK_CONN095 indicates that another CDS (Core Data Services) activation process is currently running, which prevents the consistency check from being performed. This situation typically arises in environments where multiple CDS views or objects are being activated simultaneously, leading to a lock on the activation process.
  Cause:
  
  Concurrent Activations: Multiple users or processes are trying to activate CDS views at the same time.
  Long-running Activation: A previous activation process is taking longer than expected, causing subsequent requests to be queued.
  System Lock: The system may have a lock on the activation process due to a previous error or an incomplete activation.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for a few moments and then try to activate the CDS view again. This allows the current activation process to complete.
  Check for Active Processes: Use transaction codes like SM50 or SM66 to monitor active processes in the system. Look for any long-running activation jobs and assess if they can be terminated.
  Check for Locks: Use transaction SM12 to check for any locks related to the CDS activation. If you find any locks that are no longer needed, you can delete them (ensure you have the necessary authorizations and that it is safe to do so).
  System Logs: Review the system logs (transaction SLG1) for any errors or warnings that might indicate issues with the activation process.
  Restart the Activation: If the activation process seems stuck, you may need to restart the activation or even the SAP system if necessary (as a last resort).
  Consult Basis Team: If the issue persists, it may be beneficial to consult your SAP Basis team for further investigation, as they can provide insights into system performance and potential issues.
  
  Related Information:
  
  CDS Views: Core Data Services are a way to define semantically rich data models in SAP systems, and they are often used in conjunction with SAP HANA.
  Activation Process: The activation of CDS views involves generating runtime artifacts in the database, which can be resource-intensive.
  Performance Considerations: In high-usage environments, consider scheduling activations during off-peak hours to minimize conflicts.
  
  By following these steps, you should be able to resolve the error and successfully activate your CDS views.
