ProjDateDiff Summary Explodes - Use Rollup Maximum   
When building a custom formula to find working days between two dates, trying 
to use the Formula in the Summary calculation explodes.  Using the rollup 
Maximum works fine.  

With this workaround, I am fine, but was wondering if I was doing something 
wrong when trying to simply use the formula in the Summary/Group.  I tried 
putting the ProjDateDiff formula in Duration1 and Number1 and Project crashes 
whenever I tried to use the formula for the summary of the custom field.

(Sorry, I was trying to get this in the main forum.)

Hi,

Could it be that your input dates at summary level a not all dates but NA 
f.i.?

Re: ProjDateDiff Summary Explodes - Use Rollup Maximum   
And what version of Project and are you running the latest service pack for 
it?

Re: ProjDateDiff Summary Explodes - Use Rollup Maximum   
Jan,

Thanks for your response.  One of my colleagues, an exceptional man, passed 
away recently and I have been a bit distracted.

I see no NA's.  All is well at the leaf level, but the exception 
consistently occurs when I enable use of the formula at the summary level ... 
whether the calculation is in a number or a duration.

The workaround seems to be working, but I am always anxious to know what I 
am doing wrong.   Since I have a workaround, please treat this a low priority 
amongst your many inquiries.   Again, even though this is part of a project 
involving significant programming, there is no VB code involved in this .. 
only custom calculations.

Thanks,
Bruce

Re: ProjDateDiff Summary Explodes - Use Rollup Maximum   
Rod,

Thanks.  I don't know if you spotted my repy to Jans, but my apologies for a 
late response.  (I am very much enjoying your book by the way!)

Project 2007 (12.0.6211.1000) SP1 MSO (12.10.6213.1000)

As I mentioned to Jan, I do have a workaround .. just using an extra level 
on indirection and another column ... so please treat this a lower priority.  
 I am just curious what I am doing wrong and how to learn from it.

Thanks,
Bruce
