ServiceMax has (3) fields on the product stock record which drive the auto-replenishment process for engineer stock at a location. (1) "Reorder Point" which kicks off a parts order when the inventory level at a location has dropped below that number. (2) "Reorder Quantity" for the provided product and location when reorder level is reached, and (3) "Required Quantity" which is a formula field which calculates the difference between your reorder quantity and your available quantity. This calculation determines the quantity for your new parts order based on these variables.
The feature request is for this formula calculation to factor in the "In-Transit" quantity such that an order is placed one day for parts which may be arriving the next day.
