Any best way to debug the out of the box Knowledge Model KPIs

Hi @kailash.potha12​  Can you elaborate your question?

@Preethi P​ For example, In inventory Management starter kit Excess inventory value is showing wrong. I want to check the KPI where it is going wrong. But this KPI is defined on other KPI and going on.

If i extract the entire formula which is having tens of lines and i am not able to understand how to read.

If you have any leads on how to debug these kind of KPIs will be much useful.
