Hi all,
I wonder if someone could help me.
I have several activities that start at the same time and one that starts later
A 2-12-11
B 2-12-11
C 2-12-11
D 10-12-11
I want them all to link to activity E so that E starts on the 2-12-11 however when I use a SS link it ignores the early date and starts on the 10-12-11 instead. Is there a way of linking all the activities together and get E to start 2-12-11?
thanks in advance,
Thom
If what you want is to setup e (task no 9) to start after any of a/b/c/d starts and they are independent to each other this is difficult to model by most CPM software as the majority does not allow you to create driving links to/from summary bars.
For MSP this is a walk on a beautiful spring morning along Memorial Drive on Charles River.
Sorry I could not make a correction to task 9 name, I deleted the file, I know with regard to summary bar MSP is more powerful than most other. Maybe LOE activities in P6 can handle this.
I am trying to model this with cumbersome conditional switches on Spider Project my software of choice got it for 2 activities with the use of formulas and a script but for 3 activities it is becoming very complicated. I have modeled this with cumbersome procedure using resource leveling and resource consumption and creation available in Spider. This allows for even more complicated scenarios at the cost of even more complicated setup.
I always dreamed of more intelligent links to a group of activities where ease of setup and transparency is key.
Best regards,

Hi Thomas
Set up a milestone as your start date and link that FS to all your other activities.
Never Ever use FF SS links.

You need to think clearly through your logic here. By putting SS between A, B, C & D and your activity E they you are saying activity E cannot start until each of these activities has started. The software calculation is correctly showing activity E start as 10-12-11. If you say activity E can/should start on 2-12-11 then there is not a SS relationship betweend D and E. This is fairly basic understaning of CPM logic.
