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.
Follow the below steps:
1) Create a Sales Order, filling up the basic information
2) 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
3) Release the Sales Order and drop the PO
4) For the PO, do the same procedure if needed.
5) Create a new Group Shipment and add shipment line from the picker. The fixed PI/ SI Exchange Rate will be showed.
*The default rate will not be according to SO / PO document date.
*A change of Bill Lading Date will not reflesh the rate.
*The Posted Docuement will use the Hedge Rate in G/L Entries.
