PRJ: Total Slack Calculated Incorrectly Using FF/SS Relationship |
Q107442
The information in this article applies to:
- Microsoft Project for Windows, versions 3.0, 3.0a, 4.0, 4.1
- Microsoft Project for the Macintosh, versions 3.0, 4.0
SYMPTOMS
Total slack may not be calculated correctly when tasks are linked using a SS (start to start) or FF (finish to finish) relationship and may cause a task to show as non critical.
WORKAROUND
To work around this problem, change the FF relationship between T1 and T2 to FS (finish to Start) with a one day lead.
MORE INFORMATION
Steps to Reproduce Behavior
- From the View menu, choose Task Entry.
- Enter three tasks, T1, T2, T3, and assign the tasks with a duration of 2d, 2d, and 3d, respectively.
- Select T1 through T3 and from the Edit menu, choose Link.
- Press the F6 key to activate the Task Form.
- From the Format menu, choose Predecessor and Successors.
- In the Gantt Chart, select task T1.
- In the Task Form, change the successor relationship to FF and enter a 1d lag.
- In the Gantt Chart, select T2.
- In the Task Form, change the successor task relationship to SS and enter a 1d lag.
The task T1 will calculate total slack at two days, but if the duration of task T1 is increased the end date of the project will change.
