Just to confirm the current behaviour of customer editing on OE orders, as a basis for discussion:

- When MultiCurrency is not used, you can edit the customer code while creating a new order. Once the order is posted, editing an existing order does not provide access to the customer number field.
- It is never allowed when MultiCurrency is enabled, even if all you have done is chosen to create a new order. There is underlying currency information on the order that would be difficult to change with the customer.

- Because customers can have different price levels, alternate price lists and Special prices, what would the expected results be if you edited an existing order where different pricing applied? Are you OK with leaving prices exactly as they are, or do you want the new customer's pricing for each of the items to automatically update?
- Similarly, there would be an expectation that Taxes would automatically update if the new customer has a different tax Group or Status that the original customer, correct?
- Also, should other information such as Ship-To address codes, Salesperson, Terms, Payments and other default OE values get loaded from the customer (and ship-to code) or the order left as is?
- What should happen if an Invoice is posted instead of a change to the Order?

These are things to keep in mind for this 'simple' change.
