The end date for the contract is mandatory. It can be modified whilst the contract has the status To be validated.
When the contract status is In process, this date can be updated via the Update the contract action. It can also be updated during the use of the Record the end of contract action.
This update, when the date entered is less than the previous date, leads to the deletion of the financial payment schedule for the due dates later than the new date entered.
When the contract involves company vehicles which registration numbers are provided, it also leads to the update of the lease end date (Vehicle option window of the Financial assets management function).
