User is trying to batch update the project on some time entries, but gets an error message that it cannot be done as the contract amount has been exceeded.
This happens when the target project has the rule set: Prevent time and expense entry after reaching contract amount and the amount charged on it has already reached the contract amount. You can only add non-billable and extra time entries to that project. Check out this article for more: Cannot create time entries after contract amount is exceeded.
