could you upload some data for me to build a demo for you? I will suggest using Pivot Table , or use a regular table.
You need to build the expression for EBITA , Net Income, Etc separately, and stack these parts together base on P&L format. It is hard to build it in one table or one Pivot Table.
I am an accountant too, I understand your pain , remeber qlik is a visualization tool, for showing a financial statement is not its advangtage but it is not hard, maybe someone has some brilliant ideas on this topic.
