Currently, the Planning Worksheet does not take into account the Expiration Date of Lots in Inventory. That is, if we consider inventory with an expiration date lower than the shipping date for open Sales Orders, the Planning Worksheet will not suggest produce/purchase the quantities necessary for the Order, once it considers this Inventory available. However, when posting the Sales Order an error will occur (with the active configuration on Tracking Specification) and there will be no stock available, which may impact shipping on the planned date.
