• What is the cause and solution for SAP error message CKBA091 - Error when locking objects ?

  The SAP error message CKBA091, which indicates "Error when locking objects," typically occurs when there is an issue with the locking mechanism in the SAP system.

  Check Lock Entries:

  System Performance Monitoring:
  
  Monitor system performance using transaction codes like ST22 (dump analysis) and SM66 (global work process overview) to identify any bottlenecks or issues that may be affecting locking.
  
  
  
  Database Check:
  
  Ensure that the database is functioning correctly. Check for any locks or issues at the database level that may be impacting SAP.
