Hello @anuradhauh 

Currency code for customer orders are not amendable. For Service Orders, you need to change it when you create work order. If your work order is connected to a contract ID, you cannot change the currency on work order. Then you have to have the correct currency code in  service contract.

Hope this helps

Cheers

Hi @anuradhauh 

after creating a customer order you can’t change it anymore.

It is defined in customer.
