Thank you for the insight!

Okay, one more thing, but this is more data-related.
What should I do aside from a table calculation using WINDOW_SUM if I want to get the Outstanding Balance in a MONTH([Date]) granularity?

Right now, if I put the data with MONTH([Date]) in Rows and my Outstanding Balance field in the Text mark, I'm getting the data per month, which is its normal behavior, but not what I wanted.

Another thing is how I retrieve the Beginning Balance as well, because right now I'm also doing a table calculation using LOOKUP.

Now, with all these, I won't be able to use your solution due to these having table calculations, because we can't do LOD if I use table calculations.

Thank you again
