Notice deadline from the end date

When a contract arrives whose field Notice deadline is empty, the step Set field sets it to 90 days before the End date, without a script; a deadline the AI read from the contract stays. If the end date is empty, the notice deadline stays as it is, and the history says so. Then the management reviews the contract.

The workflow

The workflow starts for every document of the type contract. Its file workflow.yaml:
