I have maybe a simple doubt, how do it sum the checked options ?
I need to have one line item showing : 3
Couldn't resist jumping in on this one. I do this all the time with my system modules.
Best way I've found is to create one more line item formatted as a number, similar to your comment line item, and 1 if TRUE else 0. Set your conditional to be the most likely so if there are more unchecked then checked then write the formula as If false then 0 else 1. You always want Anaplan to exit the conditional as fast as possible and it looks like you're using a lot of dimensions so this will be important.
The last part is to write the SUM which will just be reference (without the SUM function) if you're using a structured list. If not you'll need to use the SUM and/or TIMESUM function.
This module has no time dimension
Very well done and absolutely correct. One suggestion on the module without the time list, try to avoid using TimeSum as it is a single threaded calculation. As an alternative, in the Time settings, click on Total of All Periods and do a Select at this level (Checkbox Sum.Count[SELECT: TIME.All Periods]) , again if the target is not using Time.
If your source module is not using Time but all lists have a Top Level, then the Select will not be needed.
Hope this helps,
Selecting All Periods and enabling that is much more performant than using TimeSum.
Create another no formatted line item and put it 1 based on true boolean, then aggregate over that numeric line item using timesum
Please see above, TimeSum is not the best way to do this.
Thank you all for the solution proposed and discussion.
