I have just started on a project in Finland where we are cost loading the schedule.I am working with P6 Professional R8.2 Release 8.2.1 The problem we are having is that after loading all the costs, as soon as we try to update progress on an activity, and make any change to an activity date/duration all the costs (budgeted, actual,remaining & at Complete) associated with that activity reset to zero.Have you had any experience of such a problem or any idea how to resolve it?Any assistance would be appreciated.Kind regardsAndy Pearce andrew.pearce@teamisgplc.com
