Overview
Allows users to view Sales Documents and Purchase Orders values in functional currency. The functional currency is set up in GP at the company level and is used for accounting, transactions, and final reporting. In a multicurrency environment, you may create documents that use currency types other than the functional currency.
Use
Create a sales document or a purchase order. Select a document currency that is different than what is set as your company's functional currency.
Once saved, a button on the top toolbar will be enabled. Clicking the drop-down arrow will give you the option to toggle between Originating Currency (The currency the document was created with) and Functional Currency.

Selecting functional currency will set the document to a read-only state. You will be prompted to save the document if changes were made prior to switching to functional currency view.
