  The SAP error message TPM_THX1451 indicates that you are trying to enter a reversal date for a business transaction in a multitasking mode, which is not allowed. This typically occurs in the context of Treasury and Risk Management (TRM) or similar modules where certain operations are restricted when multiple sessions or tasks are open.
  Cause:
  
  Multitasking Mode: The error arises when you attempt to perform an action that requires exclusive access to a transaction while another session is already processing a related task.

  Solution:
  
  Close Other Sessions: Ensure that you do not have multiple sessions open that are trying to access the same transaction. Close any unnecessary sessions and try again.
  Single Task Execution: Perform the reversal in a single session. Log out of other sessions or tasks that might be interfering with the transaction.
  Check Transaction Status: Make sure that the transaction you are trying to reverse is not currently being processed or locked by another user or session.
  User Authorizations: Verify that your user role has the necessary permissions to perform the reversal. If not, contact your SAP administrator to adjust your authorizations.
  System Configuration: If the issue persists, consult with your SAP Basis or technical team to check if there are any system settings or configurations that need to be adjusted.
