Different currencies in Master Agreement and it;s Sub-Agreement

Hi Experts,

I see that the Sub-Agreement(SA) by default have the same currency as that of the Master Agreement(MA). However, by using importer, we can create a SA which can have a different currency from it’s MA.

If SAP allows the SA to have alternate currency using importer, why do it restricts from UI. We may have a business scenario where SA may be created for different countries and may have alternate currency.

Please share your thoughts on this .
