Hi @david.harmer,

So when the CO is created from the SQ the only place we could have changed this is the Create Order from Quotation dialogue box. But clearly there is no option to change the currency here. 

However, at the time you create the order make sure you change the currency of the SQ header to the currency which you need your CO to have. Even if you have multiple lines in the SQ, the created order will fetch the value in the CO header at the time of creation. 

So that, in my eyes, this is similar to the ability of changing currency in CO before saving it.
