Configure a "% of Sales" report column

[dreispt]

Having comparisons with % of sales is usual in financial statements, especially for expense accounts.
I having trouble configuring such a column.
Any suggestions please?

It's not going to be easy to put that in a column. You'll need to add rows with percentage KPIs (such as cost_of_sales / revenue...).

Greetings, I am trying to do in a subkpi but I have two problems: 1- I don't know how to format% to that subkpi column and 2- I don't know how to remove that subkpi from columns where it is not relevant.
