Good Afternoon Shubha.
Setting/Defining the Business Units for this, is the way to accomplish this in the CA Service catalog environment.
Should you have and use a 'language dependent' SC-UI through the web browser, you might consider to make a copy of each offering and translate/set the 'price cq cost details' accordingly per language being used?
Although that would be a lot of administrative work and maintenance to do, right?
Thanks and kind regards, Louis.
