If you need to cancel an amendment to a contract after submitting the change for authorisation, you can do this in the 'Contract Amend' screen.
Location: Contract Folder > Contract Amend
Search for the contract number using the filter above the table; once located, the 'Status' should currently show as 'Amended and Awaiting Authorisation'.
To cancel the amendment, click the 'Edit' button in the 'Action' column to navigate to a summary of the contract and click the 'Reject' button at the bottom of the screen.
