Matrix Table Custom Total

[Chas2002]

Hi Everyone,

I've been working with Power BI for a few weeks now and all is going well.  However, I've ran into a perplexing issues with Matrix row/column Totals, Aggregate Types, and Printing.

The problem:  I'm using time as hh:mm:ss but can't find a way to aggregate it because Power BI considers it Text type.

I have the seconds that the hh:mm:ss were derived from, so I attempted to create a custom Total column, but can't get DAX to allow me to create the column.

Please see attached image.  My datasets are Whole Numbers (Peg counts and seconds) and Text (seconds to hh:mm:ss).

Any help would be greatly appreciated.

Thanks,

Chas

Here is an article and a quick measure that might help:

Hi Smoupre,

I checked each link.  The first link will convert sec to hh:mm:ss and that's fine but I already have secs converted to hh:mm:ss.  I'll use this DAX at the BI Desktop level.

The second link is a good representation of the first link.

The third link, dealing with measures, is along the lines of what I'm in need of.  

I need to aggregate "hh:mm:ss" -- I fear that the only way to do this is remove the Total column that's part of the Matrix Table Field well and replace it with a custom DAX function that itterates over all my "hh:mm:ss" row data and aggregates to results.  This is what I need help with <-- creating this custom field for Totals.

Thanks,

Chas

I guest I'm looking for something like this in DAX?

DAX: Get Filter that's in place,
DAX: SUM(agent_interval[ACD Time])
DAX: Loop over all rows

Save that is a Custom Total column..

I guess what I was thinking was to create measure along the lines of the third link. If you are in a row or column, just display the value. If not, then use the second link to convert your duration format to seconds, aggregate and then use the first link to convert back to duration. Sample data would help me get more specific.
