Create a Resource Calendar with 9 hrs and assign it to the Resource. MS Project will start to allocate resource for 9 hrs. You are not able to see the Change in Work hrs in your Gnatt Chart Table becuase there MSP shows 8 hrs as Work on the task, while in backend resource is made to work 9 hrs.

So if you want to see the change open Resource Usage View and therein Yellow timephased sheet you can see that resource is in fact working 9 hrs on the Task which is shown 8 hrs in your Gnatt chart view. Because when we plan a task we specify its Duration rather then the resource efforts in first place.

See at the linked Snapshot:

Project Calendar : 8 hrs    Resource “h” have 9 hrs Calendar

So when I assign h to a task of 3 days – Work gets calculated as per Project Cal i.e. 3 days X 8 hrs = 24 hrs. But h actually works 9 hrs on the task to finish 24 hrs of work.

Its not a Bug of MS Project; its entirely the mixture of its various Algorithms trying to balance : Constrain Types , Start Date & PERT Chart’s Backward tracing of Late Start Date Calculation for Duration.

Replicated the Issue and found that :

As long as % Complete is 0% for last ALAP Task  >>

1. Summary Level Tasks & Project Summary Task is taking the appropriate dates as per the “Dependencies” no matter whatever the Constrain is ASAP or ALAP. This trend continues with % Complete happening until last task in the Plan with “ALAP” is marked 100% Complete.

2. The moment last ALAP is 100% Complete Project Start Date ignores all Dates and pick up the Start Date of that task as Start Date for Summary Level Tasks & Project Summary Task. Reason being now it collate all ALAP to reach to final concluding ALAP Date which gets reflected in Start Date.

MS Project Start Date use formula : Start + Delay , in this case Delay is basically what MS Project saves as backtrack float while calculating ALAP path for the Schedule PERT Chart. It cannot pick the Start Date until last ALAP is Finish.

 

NOTE :

1.     Summary Level & Project Summary Task Start Date takes “Start Date of last ALAP Task” of a Plan when it is marked 100%.

2.     Duration never changes honoring the Longest Path algorithm. Its just the Start Date that reflects unexpected Duration [here it shows 1 Day as per the Start & Finish Dates but duration Field still have 3 days.] Start Date is running on Backward tracing of the PERT Chart Late Start calculations.

3.     Exact Dates are getting captured any ways in “Actual Start” field of MSP. If we change Actual start Date, Start Date adjust themselves and still follow the above cycle for last ALAP Task.

Hope this Clarifies why Start Date takes the Start Date of Task 3 in your case when you mark it 100%., while it remains Intact when you have ALAP tasks as 0%.

Hammock Tasks


Because the hammock task relies on other tasks for start/finish information, anything that affects those other tasks (resource leveling, constraints) will ultimately affect the hammock tasks dates.

You can either control Work or Resource Units as Hammock Task’s duration gets derived from linked tasks.

If you want to Conrol Work hrs – make task as “Fixed Work” in this case with increase and decrease in the Duration, Unit % will get changed. If you want to Control Unit % – make task as “Fixed Unit” this will increase or decrease Work in proportion to the Duration

 

Say you have Hammock Task with : Duration – 2d   Unit – 1 Resource [100%]  Work – 16 hrs.

Now due to changed in linked task Hammock Task change its duration to 4 Days.

______________________________________________________________________________________________________

Fixed Work Scenario :

Duration : 4

Work Remain same [as initially calculated by VB Macro’s Duration & Resourcing] : 16 hrs

Units : R1 [25%]

Implying that now resource will work 4 hrs/day to Complete 16 hrs Work in 4 Days.

Fixed Unit Scenario :

Duration : 4

Fixed Unit : R1 [100%]

Work = Fixed Unit( hrs per day) X Duration = 8hrs X 4 days = 32 hrs

__________________________________________________________________________________________________

NOTE : Making Hammock Tasks of “Fixed Duration” works fine in duration bracket which suffice its Start & Finish tasks Dates, beyond that if manually Duation for Hammock task is increased though it maintains its Finish linked Task Date but start ignoring Start Date that is drived by other task. In that case Hammock task automatically schedule itself to Start Prior to Finish Date of task from which it was drieving its Start Date intitally.

Hope this helps 🙂

By Default “Edits to total task % Complete will be spread to the Status Date” remains DESELECTED in MS Project.

The option implies that : What ever is the “% Complete” for a task, it gets broken up evenly from Start to Status Date. When this option is DESELECTED “% Complete” gets distributed till Today.

To View appropriate reflection of this Toggle option -> Open Task Usage View -> Insert “Percentage Complete” Row in the the timephased grid (the yellow timesheet grid on the right side of the View); and try to read % Complete for 2 tasks [ 1 with this option Selected & other with this option Deselected].

Scenario :

Start Date (both Task) – 10th-Dec-10 , Status Date : 12th Dec 10, Today is 14th Dec 10.

Task Option Selected [TS]: % Complete = 70%

Task Option Deselected [TD]: % Complete = 70%

Task Usage Timephased Grid [Yellow Graph] will Show :

           10th        11th     12th     13th     14th        

TS  :    15%        15%     15%      15%    10%             [Here edits in % Complete is broken up equally till Current Date 14th Dec (here)]

TD :     25%         25%    20%                                    [Here edits in % Complete is broken up equally till Status Date 12th Dec (here)]
Hope this Clarifies.

Have been working with telecom industries for a while now (But its not limited to telecom though it was suitable for them but it can be used for othe rverticals where projects are typically spread out), as pretty obvious thing visual representation strikes more than textual data, so i was thinking over how could i do so and make it interesting, and here came the thought why not show their project status with those beautiful little colorful indicator(marker) on the map representing their status , and i started writing a module to do that, now typically i should have chosen MS Virtual earth as a map, but instead my instinct said lets paly with google API, and i started exploring the options, i wasn’t familiar with much of the langauages other than Java Script and so i started of with Java Script, now the next problem was how do i integrate it with project server as PS API (Now in My Code i Simply used Data From RDB, you may want to extend it to ) interact using .NET code and Google map with Java, so i used the trivial method of building dynamic javascript and pass it to the ASP.NET Literal control to render, though i know it could have been done much better, but i leave that to you 🙂

So here goes my code
