In the table below, “Plan Trial” is the Summary total for the 4 Sub-total tasks below it.
Each of the 4 Sub-total tasks have from 4-10 tasks each.
I have reconciled thee “% complete” for each of the 4 Sub-total lines.
However, I cannot reconcile the “% complete” for thee “Plan Trial” line. It shows as 93% (which is = Actual Duration/Duration) BUT is does not match the weighted calculation based on the 4 Sub-totals below.
Does anyone know why this occurs?
Task Name Start Finish Duration % Complete Actual Duration
Plan trial Mon 8/08/16 Fri 23/09/16 35 days 93% 32.57 days
Draft and Approve Requirements Specification Mon 22/08/16 Thu 8/09/16 14 days 100% 14 days
Prepare trial implementation plan Mon 22/08/16 Wed 14/09/16 18 days 97% 17.43 days
Plan how to place the device into the vehicle Mon 8/08/16 Fri 23/09/16 35 days 54% 18.93 days
Specify Trial Case(s) Mon 15/08/16 Wed 14/09/16 23 days 100% 23 days
I had already worked through this document but it did not give me the answer I am seeking.
I applied exactly the same logic as the example in this article, but my equivalent to the “Top Summary” does not result in the correct outcome for me.
We’ve run into two items that may be causing your scenario.
1) The Summary Task is a manually scheduled task. When it is configured this way, the automatic roll up / summarization of the sub-tasks does not occur. Change the summary task to auto scheduled.
2) There’s a scheduling option (File>Options>Schedule) “Updating task status updates resource status” that should be checked. if you hover over the information icon next to this option, you’ll see that it impacts calculations of % complete.
No guarantees, but try checking these two items.
