Changing the Decimal Notation

Hello Experts,

We have a request to change the decimal notation of values. Please consider the below example.

Value: 450000 (Four lakhs and fifty thousand)

Actual Decimal Notation in the syetm is 450,000.00 (In thousands)

Expected Decimal Notation: 4,50,000.00 (In Lakhs)

Please advice where to set this up in the system.

Thanks in advance,
