sum desperately empty?

Hello,

I have a report in webintelligence which goal is to compute the length items are loaned (in an academic library context) which is quite simple:

- one query to get the loan ID and the time it was issued

- one query to get the loan ID and the time it was returned

I have merged the two loan ID, created a dimension to compute the duration of each loan in minutes by subtracting the return date and the issue date. To get this working, in my table I had to select the Avoid duplicate row aggregation", maybe it explains the issue I experience.

I am able to get a table:

Loan ID Issued Returned Duration 302032 2015/10/01 08:43 2015/10/02 08:27 1,424

302095

2015/10/01 10:59

2015/10/01 12:08 68

This part works fine, unfortunately, if I try to add a row to compute the sum of all the duration =Sum([DurationInMinutes]) the cell containing this fomula remains empty. I have tried to transform to numbers and things like that but could never get the things working.

Has anybody got an idea what I should do to get this done?

Thanks for any advice on this!

Sylvain

    Hi,

    Try with right click on the column->Insert->Sum.

      Hi Amit,

      this is what I had tried first (well, using the toolbar but it seems to do the same thing) and this did not work. I have then tried to change the formula (adding useMerged and other things following suggestions found on the web, but nothing fixed my issue...)

      Thanks for the help,

      Sylvain

    Hi Sylvain,

    Can you share the formula used to calculate [DurationsInMinutes]?

      Hi Sylvain,

      I tried to reproduce it with single data provider and was able to get the data; therefore, I am suspecting the merging somehow.

      What do you see if you create a measure as Sum([DurationInMinutes]) and simply drag it on the report as a free standing cell (outside the report block)?

      Does it show any value or error or come as blank?
