The format directly from ERPNext
Production Cost is Direct Cost
I found out the problem, system can’t handle multi group
Sales - COGS - Production Cost = Gross Profit
Gross Profit - Expenses + Other Income = Net Profit

I get correct result for following one

Sales - COGS = Gross Profit
Gross Profit - Expenses = Net Profit
