This error indicates that the account assignment for a particular project or internal order is locked, preventing further postings or changes.
  Cause:
  The "Account assignment locked" status can be triggered by several factors, including:
  
  Project Status: The project or internal order may be in a status that restricts further postings. For example, if the project is completed or closed, it may be locked for financial transactions.

  To resolve the CN174 error, you can take the following steps:
  
  
  Check Project Status: Verify the status of the project or internal order. If it is set to a status that prevents postings (e.g., "Completed" or "Closed"), you may need to change the status back to allow postings, if appropriate.

  Unlock the Account Assignment: If the account assignment was manually locked, you can unlock it using the appropriate transaction (e.g., CJ02 for project change). Look for an option to unlock or change the status.
  
  
  Consult Configuration: If the locking behavior seems to be due to configuration settings, consult with your SAP configuration team to understand the rules governing account assignment locking and whether adjustments are needed.
