Hi,
I'm building a table card and I would like to create a column that performs a cumulative sum, like the following:
| Week | Amount | Running Total
| 1 | 100 | 100 |
| 2 | 50 | 150 |
I tried to do this using SQL Dataflow, it works fine. However, I want to be able to add filters that modifies the Running Total and thus, the approach that I used with SQL doesn't help me much (since it performs the sum of the whole dataset row by row).
Any light on this would be much appreciated
Thanks
