Change currency for a wagetype.

Hi all ,

I am quite new to SAP HR payroll. I want to change the payout currency for a particular wagetype pertaining to Infotype 2010 from SGD to USD since payout always happens in USD for that particualar wagetype. I tried to check in various views like Wagetype characteristics , V_T511 ,V_t510F and others but I cannot get to the point where i should maintain the entries and is it advisable to do so.

Can anyone pleasse guide me?
