  Where:

  Cause
  The cause of this error message can vary, but it generally indicates a deadlock or resource contention situation. Common reasons include:
  
  A transaction is trying to access a resource that is currently locked by another transaction.
  There may be a long-running process that is holding onto a lock, preventing other processes from proceeding.
  Insufficient system resources (like memory or CPU) can also lead to processes waiting for each other.
  
  Solution
  To resolve the issue, you can take the following steps:
  
  
  Identify the Blocking Process:
  
  Use transaction codes like SM12 (to check for locks) or SM21 (to view system logs) to identify which process is holding the lock that is causing the wait.
  
  
  
  Analyze the Situation:
  
  Check the details of the waiting process and the blocking process. Look for any long-running transactions that may need to be optimized or terminated.
  
  
  
  Release Locks:
  
  If a transaction is found to be holding a lock unnecessarily, you may need to terminate it. This can be done using transaction SM12 to delete the lock entries.
  
  
  
  Optimize Processes:
  
  Review the processes involved to see if they can be optimized to reduce locking contention. This may involve changing the way transactions are structured or modifying the timing of certain operations.
  
  
  
  Monitor System Performance:
  
  Use transaction ST22 (for dumps) and SM37 (for job monitoring) to monitor system performance and identify any recurring issues.
  
  
  
  Consult SAP Notes:
