  The SAP error message CM_EHFND_COMN036, which indicates an "Enqueue error in function module SO_DOCUMENT_SEND_API1," typically occurs when there is an issue with the enqueue lock mechanism in SAP. This error can arise in various scenarios, particularly when trying to send documents or emails through the SAP system.
  Cause:
  
  Lock Conflicts: The most common cause of this error is that the system is trying to access a resource that is currently locked by another process. This can happen if multiple users or processes are trying to send documents simultaneously.
  Database Issues: There may be underlying database issues that prevent the enqueue mechanism from functioning correctly.
  User Authorizations: The user may not have the necessary authorizations to perform the action, leading to a failure in acquiring the required locks.
  System Performance: High system load or performance issues can also lead to enqueue errors, as the system may struggle to manage locks effectively.
  
  Solution:
  
  Check Lock Entries: Use transaction code SM12 to check for existing lock entries. If you find locks that are no longer needed, you can delete them (ensure that you have the necessary authorizations to do so).
  Retry the Operation: Sometimes, simply retrying the operation after a short wait can resolve the issue, especially if it was caused by a temporary lock.
  Review User Authorizations: Ensure that the user has the necessary authorizations to perform the action. You can check this using transaction code SU53 after the error occurs.
  System Performance Monitoring: Monitor the system performance using transaction codes like SM50 or SM66 to identify any processes that may be causing delays or locks.
  Check for Background Jobs: If there are background jobs running that may be causing locks, consider rescheduling them or checking their status.
