Can't Find Cash Flow Mapping Menu in Accounts Module

Hi Expert,

Hello,
Does every update in ERPNEXT can delete any menu?
Because I can’t find Cash Flow Mapping Menu from Accounts module in my current version.
I need to setup my cash flow report because right now I can’t display detail transaction in my report.
Im following this instruction, but I can’t find the menu.
https://erpnext.com/docs/user/manual/en/accounts/articles/how-to-customise-cash-flow-report

Could someone give me an advice? Should I update my current version ERPNext to the new one?
But Im afraid if Im loosing other menu.
My current version is v.11.

Here is my cash flow report

Hope anyone can give me some advice.

Best Regards,
Enggar
