Currency for Operating Cost in Manufacturing/Routing


I am facing a problem to set the correct currency for operating cost in the menu “Manufacturing/Routing”.
I use this Routing in BOM, where I need to list the manufacturing activities for the price calculation.

The operating cost will be calculated base on the inserted hour rate and operating time. My manufacturing activities are located in other country which has another currency than my company currency.

My company is based in Switzerland, my currency is CHF, my production is in Indonesia, with currency IDR. Unfortunately, the currency for the operation cost is written in CHF, I cannot change it accordingly to Indonesian Currency IDR.

How can I do this?

Thank you for the help.
