Importing External Activities
In Microsoft Project, you can link an activity in another project as a predecessor or successor to an activity in your current project. These external activities display in gray in your current Microsoft project.
You can import these external activities as part of an MS Project import by setting the Import external activities option on the Deltek Acumen Options dialog box (Platforms - Microsoft). The external activities display in gray in the Activities view of the S1 // Projects tab. If you select one, you can see the predecessor/successor information on the Activity Relationships sub-tab.
If you are performing an MSP interop import, Acumen displays a log window if the system can't import external activities.
These external activities are excluded from analysis by default; however, you can include them by deselecting the option in the Excluded column next to the activity in the Activity browser pane of the S2 // Diagnostics tab.
