How do I retrieve the entity member's currency code into a financial report?

Content

I am looking for a way to display the currency of an entity in financial report sourced from FCCS.  When I have selected "Entity Currency" from the currency dimension, I need to show what currency it is referring in the report.  I do not what it shown on the entity member itself as is done in forms, because I also want to have reporting currencies selected directly as well.

I have been through the text functions, but do not find a solution.
