I wonder if anybody has had this problem. When I update the Original Duration for an activity, my Remaining duration maintains the first OD value assigned. The activities in question are not progressed, in fact it is a baseline schedule. I never remember P3 doing this and have only just noticed that P6 is doing this. I’m wondering if there a user preference or Admin setting changed for some reason. Please let me know if you have had this sort of problem. Thanks!
