[ruthra-kumar]

While creating Purchase Order from Sales Order, if default Supplier is provided, use Supplier currency as the transaction currency for the Sales Order.

1. Sales Order item with Supplier.

2. Supplier billing currency.

3. Create Purchase Order.

Old behaviour:

Purchase Order created in Sales Order currency.

New behaviour:

Purchase Order created in Supplier currency.
