Hi,
Can anyone help me on this.
I have enabled Parent Roll up functionality for Actual timeline by using project setting as refer to 1st screen shot.
Same way I tried to add duration and timeline for Planned Time line but it is not auto calculating as i notice at single time we can setup parent roll up functionality for single time line functionality as you can see 2nd screen shot
May i know manual formula to setup auto calculation for planned timeline as well or else any other solution for this
