Resource Assignment Dates not equal to Activity Dates

View Projects --> Tab "Resources" --> Mark "Drive activity dates by default". This will work for new activities.

To correct existing activities: View Resource Assignments --> add the column "Drive Activity Dates" --> mark the upmost then fill down.

Hope this helps

Does anyone know why the link between Activity Finish dates and Assignment finish dates breaks at some point?

make sure that the resource calendar matches the activity calendar 

Zoltan, All reources and activities are using the same calendars. I do not believe this has anything to do with calendars, because if it was so, the assignment dates will mismatch from the acitivty early dates to begin with, and not just after changing activity dates and re-scheduling.

In this case, the assignment dates match the Start and Finish dates of activities, but after making changes to activity dates and Re-scheduling, the assignment dates loose the link with the activity finish dates. This only seems to happen with certain activities, even though they have the same properties as the other activities.

 Perhaps, the assignment dates seem to latch onto the planned dates for some reason, and not the Early dates? I wonder if there is a setting somewhere in Primavera, which ensures the assignment dates move along with the activity early dates.

I have seen this issue being raised by quite a few patrons here with no solution yet.

did you select drive activity dates by default ?

did you select drive activity dates by default ?

Hi Zoltan, Yes I just selected that option and did F9 again. It did not make any impact on the current activities where the assignments are out of sync, however, after reading about the option it seem that it will apply to any new activities added further on. So this should be done at the start of a project. Lesson learned.

I am curious about the option, as it seems to be for Resource Driven Schedules. Where by Resource availability changes dates and durations for activities. Currently, I would not want my schedule to be resource driven, however it is certainly an added feature.

yes just like almost everything in p6 the setting that were in effect at the time the activities were created remain howver any NEW activities will have this attribiiute you can also add a column or run a global change.

global change

uptop make sure that the says resource assignment NOT Activity

where drive activity date by default equals no

then drive activity date by default = yes

Is it possible to have the activity dates drive the resource assigment dates instead? Or a quick way to change the resource assignment dates to match the activity dates?

EMMA my answer does that
