  • 1. Add "dated" events to a project
    Hello, I am managing a project that has meetings on specific dates. I need these on the actual project schedule on the proper days without "messing up" the rest of my linked events etc. Can anyone help? Thanks.

    I have looked everywhere trying to find a location to download the trial version of Project 2003. If you try to download it on the MS site it always takes you to the 2007 download. Very frustrating as I just want to download the 2003 trial version. Any help on where to locate the 2003 trial version would be greatly appreciated. thanks in advance!

  • 4. Complete percentages & durations changing behind my back
    Hi, So I have a large project with numerous major sections. The top section, which we will call "Development" is beginning to be populated with percent completes and actual start/finish dates. We are updating these every week. As some tasks are changed in other sections of the plan, percent completes, durations, and finish dates are shifting in the Development section. One day Development will be 60% complete and the next day it will all of a sudden be 51% because the tasks in this section are moving around when people edit other unrelated sections. We would like to be able to update the tasks with the percentage the developers think it is complete without this unexplained shift, and not as a percent of the duration complete. Are my setting for my project wrong? I have Fixed Duration, not effort driven for all tasks. Also, I do not understand some of the check boxes in the Calculation tab under Project Options. Do I need to check the "Move to end..." or "Move to start..." options? "Updating task status updates resource status"? On a side note: Are there MS Project Certification classes and do you suggest a specific teaching group? Thanks, Brian
  • 5. How do i find the outlinelevel depth?
    Hi again people, Is it possible to find the 'depth' of summary tasks in a project? Im trying to cycle through summarytasks from the 'deepest' to the outer summary task, and so need to be able to find the 'depth'. Does this make sense? Thanks again fro your time, Fiachra O'Laoghaire

Rnd Function in Custom Field

Postby U2NvdHQgRA » Wed, 12 Jul 2006 02:06:02 GMT

I am trying to create a custom field that will round up or just simply round 
off the duration of the tasks.  Ie found the syntax for the round function, 
Rnd(number), I've tried the following syntax scenarios Rnd(Duration) which 
yields "0 days".  What I want to use is Duration Variance but it will not 
allow the following syntax, Rnd(Duration Variance) I get a message that tells 
me the syntax is wrong.  Ie tried Rnd("Duration Variance") and it yields 
#ERROR.  Ie tried Rnd([Duration Variance]) and it yields  days  What do 
I need to do to the field name to make it work?

Hi,

Rnd is the function that generates a random number beween 0 and 1.
Better use Fix or Int.

Try: Round([Duration Variance]/[Minutes Per Day])

Hi,

I can't find Round in the MS project custom field function list, nor in the
help.
The urprising thing is: it works.

In article < XXXX@XXXXX.COM >,




Scott,
A couple of added comments. If you are using a spare duration field for 
your custom field, the Fix or Int functions will not work. I'm not sure 
why but they just don't - it may have something to do with the 
formatting applied to spare duration fields. A spare text field will 
work fine although you will need to apply a factor if for example you 
want the value in days, (Project stores all time related information in 
minutes, so to convert to days a factor of 490 must be used).

If you really want a rounded value instead of a truncated value, use the 
rounding function. It is not listed as being available for custom field 
formulas, but it will work. The syntax is:
Text1 = Round([Duration Variance]/480)

Hope this helps,
John

First ya'll are quick to respond, I appreciate the help.

But, its still not working (for me).  

Fix and Int aren't producing any change at all, my days are still going out 
to a decimal place.

Round([Duration Variance]/[Minutes Per Day]) divides my days by 480 and 
reduces them to fractions of days unless the task exceeds 480 days.

Text1 = Round([Duration Variance]/480) yields "0 days" in all tasks.

I've tried  Round([Duration Variance]) and I get not change, I've tried 
placing a comma and a zero or a whole number after [Duration Variance], like 
you would in a spreadsheet and nothing changes.  Could there be something in 
the customization of the project that needs to be checked?  If you haven't 
notice by now, I'm still new at using this program.

Hi,

We all should have been more explicit.
The reason some of the "solutions" offered work and others don't is that
Project KEEPS durations in minutes, but inDuration columns SHOWS them as
whatever you like (default days). So when you use any formula, the values in
there are inevitably in minutes.
So let's say you have a duration variance of 2,25 days or 600 minutes.
When your formula is Round([Duration Variance]) it is calculated to 600
(which is round so cannot be rounded) and displayed again a 2,25
The only solution thus consists of dividing duration variance by 480 (or to
be more precise, should you have a day definition other than 8 hours, by
Minutes Per Day, a value to be found under Field, Project, Number) and round
the result.
That works perfectly when you put iy IN A NUMBER FIELD because a number
foeld will not try to display it in any other unit than what is calculated.
The value shown will be 2.
However, in a duration field, Project will convert this value of 2
(remember, if it's duration, it is interpreted as minutes) into days and
show you 0 because rounded at 2 decimals it's les than 0,01.
So if you want the result in a duration field you have to do the conversion
the other way around again and the formula will be:

[Minutes Per Day]*Round([Duration Variance]/[Minutes Per Day])

That's it..

Greetings,

Thanks for simplifying it for me. It worked exactly like I wanted it to.
I've got to quit treating the functions as if I were in a spreadsheet.

Hi Scott,

You're welcome.
And I doin't know whether easy is the word, but by all means

- it is NOT a spreadsheet indeed
- and it is rarely "intuitive"

Greetz,

3.#ERROR message for custom field function - Bizarre!

I hope someone can help me understand this bizarre problem with a project 
plan that I've been using and evolving for the past 1 1/2 years to track a 
number of projects on a very high level (Project Portfolio Reporting):

All of a sudden my custom field functions no longer work - even a simple 
Today = Now() function.  It results in "#ERROR" being displayed.  I checked 
to make sure that I did not remove any necessary custom fields, tables, etc. 
that are used by other calculations. (All looks good)  I confirmed that I 
have the auto-calculate value set under Tools -> Opotions-> Calculation mode. 
 I pushed the F9 key just in case as well. If I create a band new project and 
I test the "Now()" function in a custom field it works great.  

THEN I stumbled onto a fix by adding a bogus new task to my existing file 
and all of a sudden everything recalculated and the function returned the 
proper value???  Can anyone tell me what is going on??  It is as if MS 
Project decided to do a 'recalculate' with this new task I added and then all 
is good.  

Please help me understand what is going on!
Thank you SO much!
