Hi Acrylon,
1) To make the order in the currency of the customer, you need to create a price list in Inventory that is associated with the US dollar currency code, and also create alternative price list items attached to this. Then assign this US price list to the customer. Without using an alternative price list, the item will always be based on the home currency.
2) Order Entry Invoices and Credit Notes are considered 'complete' when they are printed. Only printed invoices/credit notes will be copied to history and eventually purged from current.
