Scheduling conflict dialogue box

Thank you for your quick reply.
I hadn't saved a baseline but the task I was trying to mark as 100% complete yesterday had slipped - it had Sept dates in the Start and Finish columns on the plan (not constraints, those were the dates that Project calculated).

The only calendar in the information column is on the final task, product launch. That task uses a non-standard calendar that I created, so the product launch would be scheduled for a weekend only.

Also, the final task has already been marked as complete.

thanks

I've emailed the project plan to info@stl-training.co.uk with the subject line "FAO: Tanya - scheduling conflict dialogue box enquiry".

I tried using the filter, but that resulted in the task text disappearing and all I could see where the minus boxes that let you hide/show tasks under a summary task.

Thanks
Clare
