Hi All,

I have created a Master Plan with multiple sub projects, using Microsoft Project Pro 2010. My Critical Path has negative slack, which is properly displayed on the Master-plan, however when I open a subproject, that is in the Critical Path with negative slack, the Total slack shows zero days instead of (-)xx days.

Example:

In the Master Plan, The last task on Project A is a milestone, that is linked to the first task on Project B.
In the Master Plan, Project A has (-16) days of Total slack and Project B has (-16) days of Total slack.

When I open Project A - Total slack is zero
When I open Project B - Total slack is (-16) days

I have run some tests but none seem to solve the issue:
1.I have selected and deselected Multi Critical Path box - Still show the same issue
2.I have selected and deselected the "Inserted Projects are Calculated Like Summary Tasks" - Still show the same issue
3.The calendar is the same across all the sub-projects and Master-plan.


4.The Custom Fields are the same across all the sub-projects and Master-plan.
5. I have Service Pack 2 on my PC



Has anyone came across with this issue?

Thank you for your help in advance
