How to change Position Currency in Cross Currency Swaps?

Hi experts,

I am trying to create a CCS (Cross Currency Swap) Product Type 62B. The system determines Position Currency as MXN. I think that Position Currency must be EUR. Do you know How to change Position Currency?

Customizing data:

Company Code has Local currency: MXN

Transaction data:

Outgoing Interest: MXN

Incoming Interest: EUR

Regards,

Arturo.
