• What is the cause and solution for SAP error message C$864 - Several reports are blocked by other users, & not executed ?

  The SAP error message C$864 indicates that several reports are blocked by other users and therefore cannot be executed. This typically occurs in environments where multiple users are trying to run reports or transactions that are locked due to ongoing processes or user sessions.
  Cause:
  
  User Locks: Another user is currently executing the same report or transaction, which locks the report for other users.
  Long-Running Processes: A report or transaction may be taking a long time to execute, causing other requests to be queued or blocked.
  System Configuration: Certain configurations in the SAP system may lead to locking mechanisms that prevent concurrent execution of specific reports.
  Database Locks: If the report interacts with database tables that are locked by other transactions, it can lead to this error.
  
  Solution:
  
  Wait and Retry: If the report is being executed by another user, you may need to wait until that user completes their task. You can retry executing the report after some time.
  Identify Blocking Users: Use transaction codes like SM12 (for lock entries) or SM21 (for system logs) to identify which users or processes are holding locks on the report.
  Contact the User: If you identify the user who is blocking the report, you can reach out to them to see if they can complete their task or release the lock.
  System Administrator Intervention: If the locks are not being released or if there are long-running processes, a system administrator may need to intervene. They can analyze the situation and, if necessary, terminate the blocking session.
  Optimize Reports: If certain reports frequently cause locking issues, consider optimizing them for better performance, which may reduce the time they take to execute.
  Review Configuration: Check the system configuration to see if there are settings that can be adjusted to allow for better concurrency in report execution.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and manage lock entries), SM21 (to view system logs), and ST22 (to check for dumps).
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific reports you are trying to run.
  User Training: Ensure that users are trained on how to manage their sessions and understand the implications of running long reports in a shared environment.
