This feature is available if you have a specific export called 'order_history.csv/txt' pulled from your ERP (this will vary by brand.) It allows you to see all order history data on Elastic that is pulled from your ERP. Everything from account numbers, Elastic order numbers, your ERP's order numbers, order dates, order types (pre-season or replenishment,) tracking info, and whether it's been invoiced by your ERP yet will be available here.
Filter and Export
There is a filtering feature (to the far right of the screen) and an export feature (csv, xml, json) which you'll see an option for in the bottom left corner, below the data box.
