Calculated dimansion with sum

[AntoineL1]

Hello everyone,

I have some difficulties to calculate a dimension. I would like to build a dimension who allow me to filter to different values (10 000, 50 000,100 000, -10 000,...) to show me only the values > or <.

The problem is that i have to use the function 'sum' to calculate the number below (and it is a difference between 2 number).

If you guys have some idea, please let me know !

Thanks

Antoine
