Transaction Currency defaults to USD, and the picker does not have any additional values by default.
When manually creating a Purchase Order, the upper form includes a block called Currency Information. There is a field in this block called Transaction Currency. The field defaults to USD in our instance, but we do not have the ability to choose another value if for example we are creating a Purchase Order that should use Euro's as the transaction currency. Within uDesigner the Element Property name is currencyid, and the data definition is Currency Picker. I was able to find where I can add additional currencies to a project through the details, then currency tab. From a business perspective
