Cannot change Original Duration in P6 2.0

happened to me as well. Check the relationship and restrictions on the activities, check the calendar.

Hi,

There are many possibilities  but may this due to acess in some or all activities

If P6 works similar to SureTrak with regard to original, remaining duration and percent complete then only if selected activity is not in progress nor 100% complete a change in original duration will trigger a change in remaining duration. In order to see date changes the schedule should be re-scheduled.

About baselining in P6 I have heard that when baseline is not specified you will see planned dates of current job.

Alexandre,

You are not using P6 V2.0; that software was issued in 2001.  You may be using P6, Version 6, Service Pack 2 (sometimes called Version 6.2).

Unlike MS Project, P6 does not default to automatic CPM calculation whenever any parameter changes (you can set it to do this but this is not the default setting.)  Once you updates are complete, then you should recalculate the CPM (F9 Key or menu items, Tools / Schedule).  You really should consider taking some classes on CPM and on using P6 – there is a lot to learn.   Good luck!

I learned the planned date concept the hard way in primavera p6;

For some reason, I got xer file from my college and we don’t have the same original duration for some activities, I check every possible p6 calculation, calendar, options, without success. two days later, and  After some hard googling

I founded this excellent paper

http://www.ronwinterconsulting.com/Understanding_P6_Dates.pdf.

Now, I just make a global change, planned start = start, planned finish = finish.

Ronald,

my customer is working with Primavera 6.2.1, as stated on the 1st line of the XER file; we are both experienced enough with Primavera apps to know that automatic scheduling is off by default

the problem is that the software does not change the task finish date on the current project when you change the duration but on the "primary baseline" task (I am putting quotes because the schedule does not have a baseline)

the software does not reschedule the project from the new durations either

Check on the following setting, it might be the cause of the weird behavior. Alexandre, remember I do not use P6 and as well as MS Project I import the files into my software.

"You moved from Guatemala to Guatapeor" in English; "you moved from Guatemala to Guataworst"; in CPM jargon "you moved from from MS Project to P6".

Not all the issues with P6 are due to their infamous bugs but at times because of poor design, too many redundant fields and settings that will drive you crazy. Obviously if you do not figure out their obscure settings it is not because of them but because of you.

Best regards,

Rafael

P.S. It is always good to hear from you.

Hi Rafael,

thank you very much for your help: the issue we were facing actually was coming from this option being un-ticked, I guess because of the import from MS Project

my customer really appreciates the time you've spent to answer our question

Alexandre

P.S. I am really glad you've decided not to leave PlanningPlanet, your contributions are always very interesting

Hi Mimoune, ouash rak? still in Bethioua?

you are right, the issue was coming of the difference between Original and Planned Duration, or Early Start and Planned Start Date

thanks to you, Ronald, Rafael and Paul in Australia, the issue is solved

long live PlanningPlanet!
