Max function

Hi All,

I have a set of projects which have issues logged against them. Each of the Issues can have multiple Issue Update Comments.

I would like to be able to evaluate the 'Date of Update' column and display the newest 'Issue Update Comment', highlighted below in blue.

I understand that this can be done using the 'max' function on the 'Date of Update' field. Unfortunately I am having some difficulty implementing this.

I have been able to successfully retrieve the latest update date using the below function in the script (and grouping by Issue ID):

     max(DateOfUpdate) as IssueUpdateLatest

However I am unable to return only the latest update which results in duplicate records in any tables created.

My data looks like this:

ProjectIssueIssue IDIssue Update IDIssue Update CommentDate of Update
AlphaFunding Issue100101Recently identified an issue with  the funding01/02/12
AlphaFunding Issue100102Have spoken to John and am working on fix15/02/12

BravoResource Issue120121Resource probs update12/08/12
CharlieBranding decision130131Logo decision not made28/08/12

Any help would be much appreciated.

Many thanks,

Re: Max function

Beware of performing the Max() in the script as it will ignore any user-selections.

In a straight-table chart, with all of the fields in your table above as dimensions, add this expression:

Max(TOTAL <Project> [Date of Update])

This will show you the date of the latest update for each project (just to demonstrate the logic).  Now, in the dimension tab, expand the + next to Issue Update Comment and double-click "Text Color".  In the expression box, write:

IF([Date of Update]=Max(TOTAL <Project> [Date of Update]),Blue(),Black())

Hope this helps,

Re: Max function

Hi Jason,

Thanks for your very helpful response.

If I wanted to limit the records displayed so that only the latest record was shown, how could that be done?

Re: Max function

Maybe try as your expression:

IF([Date of Update]=Max(TOTAL <Project> [Date of Update]),[Date of Update],0)

Hope this helps,


Re: Max function

Try with FirstSortedValue which will help.

May be like FirstSortedValue([Issue Update Command],Aggr([Date of Update],[Issue ID]))
