hi sudha,

it may be 21 jun 20 is sunday as holyday in your calendar.

in p6, i have used 12hr 7day work week calendar 6.00 am to 5.00 pm (with 1 hour break so productivity is 11 hrs per day). so when i add a new activity in the schedule with 1 day duration, it shows correctly as i.e duration 1 | start 20-jun-20 6.00 am | end 20-jun-20 5.00 pm. which is correct, however, we i increase the duration to 2 days (or more), it shows me as duration 2 | start 20-jun-20 6.00 am | end 22-jun-20 8.00 am. i’m confused. any idea why is that? ideally it should be (if it is 2 day duration) start 20-jun-20 6.00 am | end 21-jun-20 5.00 pm right?

appreciate your support and response. big help.

it can be for a few different reasons. i would suggest you fix all activities to start at the same time of day.

you’re welcome!

thanks a lot for your quick response michael.
actually there are not partial durations : however, the summerized original duration in case of 8hr/5day calender related actvities are partial at wbs level since the project default calendar is 24hr/7day. moreover, the partial caculations can be seen only for total float and free float of activities having 8hr/5day calender.
also, i set calendar time periods according to employer request and general specifaction documents so i do not think it would be possible to change those settings.
again thank you so much michael. thanks to you i could improve a lot and learn new things.

sarah, this is not a good approach. since you are using 2 different calendars, you would definitely expect to see partial total float & partial free float. these shouldn’t be a concern for you – why would they be a problem?
you can easily correct your partial durations however, but checking your calendar time periods are properly set before you enter in durations.
i would advise you to remove those lags – lags are not encouraged in schedules as they are often used to “hide” time.

rahul,
this is a very complex question and i just can’t answer it here in a comment.

it’s a manual effort that way – you’ll have to create 4 世界杯时间比赛时间 , and assign them to activities individually.
another way is to create 1 resource, with a max units/time of say %400 (ie 4 世界杯时间比赛时间 of this type) and then to assign to activities. this way provides more flexibility if the 4 lathes are all identical.

ah, i see where you’re going now.
p6 isn’t a great tool for managing individual work assignments in this way. it was designed more to schedule a pool of 世界杯时间比赛时间 . like this:
if you have 7qc 世界杯时间比赛时间 who work 10hr/d, then for r-1, you set the max units/time field (see units & prices tab) to 70hr/d. this is how you represent your capacity to accomplish work (ie: the number of 世界杯时间比赛时间 of type qc).
assign r-1 to activities as you normally would, schedule the project of course.
on the resource assignments tab, with some finnagleing, you’ll be able to see what activities & days you have work assigned, and how many hr/d you need.

tanvir. the field “budgeted units / time” won’t summarize or roll-up to a bar. the only way i could find to see the 30hr/d is on the resource usage graph with the timescale set to “week/day”.
however, you could try this. rather than assign 3 different q/c 世界杯时间比赛时间 , or even the same q/c resource 3 times on an activity, try assigning that resource just once to the activity. then you can set “budgeted units / time” to 30hr/d.

hi segun,
in truth, i’m not sure what the standard is. nowadays, i tend to use 22 working days in a month, sometimes 21.5. but of course, it depends on what country you are in and what industry. here’s a link to some discussion about it: https://www.quora.com/what-is-the-average-amount-of-work-days-in-a-month

many thanks for your post. it is indeed very helpful. my start and finish times became distorted and i became confused. your video helped me solved it even before i finish watching it. i will like post my solution here for others who might perhaps be facing the same problem to benefit from…

===

when the start and finish times of activities in a schedule are distorted. it may be that you’ve changed calendar or hours of work per day or thereabout.
you need to first solve this problem by going to your calendar, click on detailed work hours/day radio button, then click on modify => workweek to set your work hours. and then click on time periods to set it as well.
then go to the user preferences => time units and under the durations format, change the unit of time from day to hour and close the form.
then reschedule the project, your original durations column will show you the hours for each activity, however, that might be wrong. in order to really know the correct hours primavera is using to calculate each day, type in 1d and click enter. you will then see the correct hours primavera is using to calculate each day. enter 1d for all the activities and reschedule the project, you will see that the start and finish times will be corrected to suit the time you set in the calendar’s ‘detailed work hours/day’.
now, go back to the user preferences => time units and under the durations format, change the unit of time from hour to day and close the form.

however, micheal, please how can i calculate the time periods without any mistake, i saw in your video that you used 12 – 72 – 288 – 3744 for a 12-hour x 6 day workweek. my own calculation is 12 – 72 – 312 – 3744. yours has 24 working days in a week while mine has 26 working days in a month. can you please explain how you calculated yours. i just want to make sure i’m following the right standard.

thank you very much.

it’s only in older versions of p6 that global calendars are used to calculate the duration shown on wbs lines. i’m not sure when it changed, but i think v8 and up.
now it’s the project’s default calendar that is used (listed on the defaults tab of the project).

i am unable to give users access to change the global calendar – they would go in and change things without a second thought . they have to contact me prior to printing to change the default global calendar.

has anyone approached oracle to get a change incorporated to fix this? much like critical path (defined float days vs. longest path), in the project settings something like “use global or project calendar to display overall duration”. i am familiar with the schema it would seem not take that much to point from a global to a “default” project calendar for calculations. thanks.

i’m sorry soud, but i can’t think of how you can accomplish this in p6. it’s the reverse of what p6 does. in p6, you enter durations, and the cpm scheduling algorithm calculates the dates.

you are welcome.

helped faster, thanks michael

those activities are start milestones so they don’t have finish dates.

hi michael, in the video there are empty cells under the finish column, may i know how to leave it blank?

hi najam,
yes, that’s one way to approach it. just to be clear, a global change cannot be applied to a calendar as you say – only to the project’s activities to alter the durations.

hi michael,

i think rohit does not want to change user preference and keep both 8 hrs and 22 hrs calendars. i will suggest to make a global change and multiply original duration of 22 hrs calendar by 0.3636, which comes from 8/22.

this golbal change should not be applied to a global calendar but project calendar, otherwise whoever will be using global calendar will change duration in their schedules too, what do you suggest michael?

rajesh,
there is nowhere to set a default start time for an activity. often the start time is set based on the finish time of the predecessor. two things to look at that might be influencing the start hours.
1) the data date – what is the time for the data date? your start time might be picking up 0:00 from the data date.
2) the project’s start date (& time) on the project screen->dates tab. look at the hours set there as well.
correct these, correct predecessor finish time and you should get back on track.

good day…

while updating the schedule, p6 picks 00:00 hrs as default start time when the user does not show the time in user preference. is there any option to change the default start time 00:00 hrs because almost all activities in my schedule starts at 08:00 hrs?

thanks,
rajesh

regards,

michael john

you may have a partial duration. goto edit->user preferences -> time units and add decimals to duration. check the durations of your activities to see if any are partial.

good day!

i just want to ask regarding duration and calendars,for example in my programme i have 1 day duration start date is 01 june 2016 and finish on 01 june 2016 same day, and the other is 1 day duration 01 june 2016 finish on 02 june 2016. how we can fix this?

thanks,

john

eric you should care about lag. when you change hours, calendars; lag stay same as original hour. i had same problem

thanks.

thanks for the very helpful tutorial. however i would like to ask how to apply this change to the activities which have actual start dates. should i change just the remaining duration part?

thanks in advance.

in my schedule i am using 2 schedules . one is 6 days per week, 8 hrs calendar, the other is 22 hrs per day , 7 days a week. the problem i am facing now is that the durations in the wbs which is assigned the 22hr-7day schedule have increased considerably and i cant seem to find a solution for this problem. the user preference are 8hrs day, 48hrs per week, 208 hrs per month and 2496 hrs per year.

awaiting your comments / recommendations .

thanks

keith, thanks for this alternate method and the warnings! i think all things we suggest here come with an underlying warning! i may have to write this up a post – full credit!
michael

an alternative method is to target the remaining finish date (and completely ignore underlying durations):

– baseline project(s)
– set primary baseline to above
– create a layout, showing the before and after view [using bl1 above]
– filter your data to show target activities
– run a global change performing the following actions, in order…

– set “calendar” to the desired calendar
– set “remaining finish” to “bl1 finish”

this should work for most scenarios, as setting the “remaining finish” effectively forces primavera to re-calculate the equivalent working hours to achieve said result. this means you don’t have to perform a forensic inspection on the calendars/hours.

warning 1 (applies to both methods) – the global change may not yield “to the day” results, unless your target calendar happens to be a 7 day working week.

warning 2 – might not work.

i am working on a schedule which has 8 hrs per day duration and 5 days a week. however ther;s one wbs which has activities of 10 hrs per day and 6 days a week. this wbs i am copying from a different project. after copying this my durations in overall project are changing,
please can you suggest me the solution to this?

thanks

when i change from third calendar to the second calendar, my activity duration changes, increases, even in hours. it appears as if the activity coincides on a non-working day in the third calendar, when changed to the second calendar, these non working days are added up to the original duration.

how do i stop this?

thank you.

thanks!

what did you try? you’ll have to provide more details.
michael

(i’ve written the same at the linkedin.)

i have been watching your video tutorials about how we can schedule one project using more than one calendar but unfortuntely i don’t understand yet the moment you are talking about global change. would you be so kind and tell me what data defines your global change (original duration, calendar, working days?? and do you do it…if=(….), then=(…) else=(….)). i have tried to use this but my results doesn’ make any sense. for instance at the column working days for an activity i have 200 when i should have maybe 20. it’s a big difference. thank you for your help.
