Logic?

Hi,

As I understand , you have a Conditioned Link.

Suppose activities B,C,D,E,F two of them need to be linked to activity A Just when any two of them has been completed.

To translate the upmentioned statement into Logic fomula:

1-First of all export your program to excel format.the format should have at least the fields"ID,percent progres,Predecessor"

2-in the field of the predecessor you will write for each of the five activities the fomula with if statment"IF %Progress=100 Predecessor=FS".

3-you will need to know how to link Exel files to Primavera.othrewise you will import the file back again to P3 each time you update your progress.

Hi Ali,

That is a good idea, but will only work when two activities are 100% complete. How do I link them for forecasting, which means when the first two are scheduled to be completed, the "A" can proceed?

If B,C,D, or E early starts change due to updatiing how can "A" link itself to the first two of them in early start sequence?

Hi Paul,

I seem to remember having asked P3 about this one a while back. They had no real answer that could solve the problem, other than by some means of regular "physical" checking of the network, and by adding a logic link at the appropriate time.

Sorry, its not the answer your looking for.

Dear James,
Thats what Im doing now, physically checking the pred start dates and linking the succs manually to the first two.
I think thats the only way, thanks,
Paul.
