To avoid double order entries, it is best practice to import and export order from the working order of the order you wish to update.
To do so, please navigate to the Orders tab.
In the orders tab locate the order you want to import or export and mouse over the right side of it to reveal the options menu.
Click the pencil to edit the order.
To export the order click the EXPORT .XLS button at the bottom left of the screen and choose a format.
To update the order with an edited XLS click IMPORT.
This will take you to the following screen.
Drag and Drop your XLS file onto the "DRAG FILE HERE" location.
You will receive a message if it was successful or if there were errors when it completes.
