FFA

As a FFWD
I want to prevent users from deleting a freight purchase once it has been used in a file reference
So that financial records remain accurate and audit trails are maintained.

Acceptance Criteria:¶

1. Freight Purchase Usage Check:
   • When a user attempts to delete a freight purchase, the system must check if it has been linked to a file reference.
2. Restriction on Deletion:
   • If the freight purchase has been used in a file reference, the system must:
     • Disable the delete option for the user.
     • On hovering on the delete button, display an error message:
       "This freight purchase cannot be deleted as it is already linked to a file reference."
3. Audit Trail & Logging:
   • Any modification attempt should be logged in the system for audit purposes.
   • The log should include the user details, timestamp, and attempted changes.
