Display resource allocation cost in Euro and GBP

Hello Planners,

Working with P6 8.4 on a France / UK project, I need to display the resource daily rate and budgeted cost in Euros for the french resources and in GBP for the english ones at the same time

I mean, I cannot answer the project director's needs with the P6 functionality of displaying all the cost in Euros or GBP according to the View currency in User Preferences.

Basically, I would assign only one € resource and one GBP resource to every activity.

I tried using cost UDF's and a Global change, with no satisfying results.

Thanks for your help,

Alexandre
