  The SAP error message CMCL101 indicates that a specific item (denoted by &1) is currently locked by another user or process (denoted by &2). This typically occurs in scenarios where multiple users or processes are trying to access or modify the same data simultaneously, leading to a conflict.
  
  Cause:
  
  Concurrent Access: Another user or transaction is currently editing or processing the item, which prevents other users from making changes.

  Long-running Processes: Sometimes, background jobs or long-running transactions can hold locks for an extended period, causing other users to encounter this error.
