Activity driving, links problem

Need Hels guys..

ive been using MS Project and P3 for almost 5yrs above and recently ive changed to Enterprise P6 8.2, my problem is when i create my 1st schedule in P6 8.2 after setting activities, duration, predecessor, successor and all, when i change the activity's date its successor date and barchart do not follow its predecessor finish date. for example, i put activity 1 to dec.1 to december 5, and its successor to dec.6 to dec.10 but when i change acticity 1 to dec.1 to dec.3 (or change its duration) its successor remains in dec.6 and not driving or following its predecessor to dec.4. unlike P3 or MS Project it automatically move the date and barchart with respect to its predecessor. there is no float, no start date or % completed since its only for Plan and for baseline schedule. can anyone advice me on this..please..thanks

you need to schedule your schedule by pressing F9 or look for the icon at the top looking something like an table clock with a play button on it

 

Once you will schedule your project on a particular data date primavera will run forward and backward pass both in order to give you the longest path

Ryan:

Just as with Ms Project, there is an option (under Tools>Options>Calculations>"Calculation mode: manual or Automatic") to choose wether the software re-calculates dates, float, etc automatically after each change or, only when you tell it to

P6 has the same option -under F9 > Schedule Options > "Schedule automatically when a change affects dates"

 

The only difference is that P6 has the setting turned to manual by default, and MS Project has it turned to automatic by default.

 

If you want to keep it as manual (which I personally prefer -it saves a lot of time when developing bigger schedules if you don't have to wait for the software to recaclualte after every change), you just have to go to F9 > "Schedule" to force the recalculation whenever you want.

Ryan,

I suggest, if you create a Project Schedule, just input the duration and the link then the apllication will do the schedule after pressing F9.

You don't need to encode the Dates.

In P3 and MS Project there is an option that will Automatically Schedule the Project but in P6 that option is I think not available.

Raymund,

thanks for your response. but my point is im still in the planning stage and setting up my baseline. i have no actual inputs and no actual data to schedule. my point is after setting 300 activities link together (300 for now and 1000 more to go), setting successor and predecessor, if i adjust the duration or start or finish dates of the first activity or any activities in that link its successor should follow its predecessors. same as in ms project and p3. but in P6 (my problem) successor dates dont change that leads me to change each 299 activities start date so that it will follow its predecessor. thats a lot of work.. driving columns of predecessor and successor has already have check mark. but still its like it have a constraint which is i checked there no constraint on that dates. please anyone have a suggestion or do i need to change any settings in P6?
