Hi 
There are just three levels of hierarchies in PL and BS reporting in the Standard version of COA. The terms "Account Name," "Account Type," and "Internal Group" refer to three-level hierarchies.

In the order of "Level 3," "Level 4", "Level 5", and "Level 6," hierarchies such as "Total Manufacturing Cost," "Cost of Goods mfd," "Cost of Goods Sold," and "Income (Loss) after Admin Exp" must be included in the old version. 

Thus, we set up testing branches and installed an Odoo instance. Although we were unable to locate the profit and loss module, we were able to locate the cash flow Python file. Attempts were made to add further levels in the cash flow COA, however the intended result was not achieved. Could someone kindly provide guidance on how to use their built-in Python module to alter the CoA?
