  The SAP error message /ACCGO/CMGL_APPL190 Wait &1 seconds. Trying to lock application document again. typically indicates that there is a contention for a lock on a specific application document. This can occur in scenarios where multiple users or processes are trying to access or modify the same document simultaneously, leading to a locking conflict.
  Cause:
  
  Concurrent Access: Multiple users or processes are trying to access the same document at the same time.
  Long-Running Transactions: A transaction that takes a long time to complete may hold a lock on the document, preventing others from accessing it.
  Deadlocks: In some cases, a deadlock situation may arise where two or more processes are waiting for each other to release locks.
  System Performance Issues: If the system is under heavy load, it may take longer to acquire locks, leading to timeouts.
  
  Solution:
  
  Wait and Retry: The message indicates that the system will wait for a specified time before trying to acquire the lock again. In many cases, simply waiting for a few seconds and retrying the operation may resolve the issue.
  Identify Lock Holders: Use transaction codes like SM12 (for lock entries) to identify which user or process is holding the lock on the document. You can then communicate with the user or investigate the process.
  Optimize Long Transactions: If a specific transaction is taking too long, consider optimizing it to reduce the time it holds locks.
  Review System Performance: Check for any performance issues in the system that may be causing delays in lock acquisition. This may involve analyzing system resources, background jobs, and overall system load.
  Increase Lock Timeout: If the issue is frequent and cannot be resolved through other means, consider increasing the lock timeout settings in the system configuration. However, this should be done with caution, as it may lead to other issues.
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or patches that may address known issues related to locking mechanisms.
