Hi Larry Thanks very much for your prompt reply. I think your suggestion is great. If I understand correctly once confirmed I should enter a task for the training dates e.g. 2 days duration, making it stand alone. So therefore it displays visually on the Ghantt Chart. Ensuring that it has no predecessors or successors. Thus not impacting on the schedule. I would then enter the dates in the Instructors resource calendar the actual training days as an exception, so that they are not available for any other work. Would work, do you agree?
