Finding brokerage charges related to a specific order or equity

How to find the brokerage charges related to a specific stock in Zerodha.For eg when i use Q back office tool to find absolute P&L it shows the profit or loss for specific symbol, but the charges are listed as total for all the equities.I want to find the brokerage charges levied for a particular transaction?

The easiest way to do this is by looking at the contract note emailed to you on the day you did the transaction.
