Set analysis problem

Hi all,

I'm trying to convert expressions on a dashboard to use Set Analysis instead of IF to see if there are any performance improvements.

The tables on the dashboard tab need to be "static", meaning you cannot make any selections and these tables are not affected by selections on other tabs.

So far I've set the tables to read only and I also have a macro that detaches the tables as soon as a tab is selected. I don't find this very practical so I wanted to have a go with Set Analysis.

Current IF expression:

sum(if(week_start=var_current_max_week AND _Market = 'My Sales', Revenue))

- working fine

New Set Analysis expression:

sum({1<week_start={'$(var_current_max_week)'}, _Market={'My Sales'}>} Revenue)

- I can't get this one to work... it's returning much higher values and it doesn't seem to be applying the set analysis on these fields.

What am I doing wrong?

Hi,

Try this.

sum({1<week_start={'$(#var_current_max_week)'}, _Market={'My Sales'}>} Revenue)

Hi Kaushik,

I have tried that before. It's not that, the dates are in the same format.

Something is weird because if I remove the 1 from set analysis it gives the correct result.

Problem is,it will be affected by selections on other fields.
