Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Dear all,

If for example I have one activity that has been commenced on the 4th of Dec, then the activity was paused on the 6th, afterwards it has been proceeded again on the 12th of Dec and totally finished on the 18th of Dec, how can I reflect that gap of the current case on the actual units in the resource assignment? my file divides the total number of hours equally on each day which is not correct. Kindly advice what to do

 

Thanks a lot

Suhaib

Unfortunately, Primavera only allows for 1 suspend & resume per activity.

If you are looking to show more than 1 suspension period for an acticitiy then you will either have to split the task into smaller activities, or set up an activity specific calendar as Annon suggests - although this can get messy quickly if there are multiple activities where the task is being suspended at different times. 

If going the Calendar Route, make sure it is a Project Specific Calendar & not global.

If more than 1 suspension period I would recommend splitting the main activity into smaller activities with a comment included to highlight that this has been done to correctly show the Actual Resource spread.

If splitting the task, you then have the option of adding an activity between the tasks to highlight the reason for the split - this would have no resources allocated to it & would allow you to highlight the delay's to tasks if required.

EDIT: Another Option could be to use the Store Period Performance option within Primavera.

See description in the following link:

Suhaib,

If you want to report start/finish of activities using specific days you should be able to do so while at the same time use a week time scale and report resource effort/usage using a weekly scale, it should be at a click of the mouse.

Activity-Performance04

The option to use calendars is another way, frequently used to model rain interruptions, it is nothing new, it works and is accepted; but the software most likely will still distribute remaining effort evenly for the current remaining duration if using time periods, if not using time periods it might re distribute evenly along all activity duration (past/actual and future/remaining).

You said - "my file divides the total number of hours equally on each day which is not correct", this means you must update your schedule in a way the software knows what is the correct distribution.  Please be reminded that because of the way P6 works you must use time periods to keep past periods distribution frozen. 

Primavera Progress Reporter might help to tame the data entry; I understand there are several other options for P6.

Good Luck

I never said you stop your project. I said you try to define specific calendars for specific purposes. Now if you can feel that your schedule is wrong in the first place then there's no harm in discussing it with your superiors. Or perhaps you just don't know how to use the software? You can always call technical support. Or here in PP, I believe that there were lots who really know the software "inside-out", but not necessarily planning and scheduling.

Thanks a lot guys,

Anoon what I meant by gap is pausing the activity itself and starting another activity, then coming back to that activity afterwards, I did not mean to stop the whole project

Rafael, the thing is that my client's planner is strick and needs every single step to be reflected in the schedule as it has to be. On the other hand, the interval of the timescale of my schedule is shown as week by week not in a day by day 

Steven, what if the activity suspension was not only for one time?

Your scheduling software shall allow you to display all interruptions clearly as well as to report on what happened every day (hours worked on activity, hours worked by resource, units produced etc.).

Activity-Performance

Even when the scheduling software can do it, comes at substantial effort, way too much. 

For a local job such as a medium rise building you might have over 250 employees.  Collecting this data is a monumental task better done through your accounting system, a system that can be audited, that can track every payroll item, that can track actual production units and report unit job costing as well as unit production rates.

At home we know how to go into such granularity using our scheduling software but we consider it impractical and unnecessary; we simply update our schedules paying attention to what is still to be done.  We model our schedules using our scheduling software, something accounting software cannot do, this is where scheduling software shines.  We keep record of activity performance in our scheduling software without over-doing it.   
  • There is no need to get into such details when updating the schedule, a simple note to keep record of days not worked is enough.  In case of a claim; accounting records, scheduling records, communications with the stakeholders and other supporting documents give us all we need, better than relying on schedule updates only.

Use the Suspend & Resume dates on the status tab.

Enter the date / time that an activity was stopped in the suspend field, then enter the date the task was restarted in the resume date.

The actual finish date needs to be after the resume date.

Only one suspend / resume date is available per activity.

Regards,

Steven

Try to define a resource calendar that will exactly corresponds to your working days and stand-by or non-working days.
