Hedge Rate can be used to fix the exchange rate (to be default) from the order to the Group Shipment.
By changing the Bill Lading Date it will not affect the Posted Invoice Exchange Rate (Purchase / Sales).
Please go through the tutorial of how to create a Group Shipment on Group Shipment Process
Please notice that the function only works for Foreign Currency used in Orders.
Follow the below steps:
1) Search & Go to "Currencies"
Click the Exchange Rate
Set the Local Currency's "Fix Exchange Rate Amount" = Both
2) Create a Sales Order, filling up the basic information
3) Go to “Invoice Details", adjust the exchange rate by clicking the right-side detail box and turn on the box "Use Hedge Rate" if users want to fix the exchange rate for this sales order
4) Release the Sales Order and drop the PO
