Within SYSPRO, Families and Groupings refers to the various collections of inventory items classified in a way that is meaningful to your business (e.g. you could classify a filter as an OEM product, a spare, a paper filter, or an oil filter). The need for Families and Groupings arises from a business scenario where, owing to the number of stock codes or stock keeping units (SKUs) the forecasting of individual stock items would constitute an unmanageable workload. It also makes sense to collect common stock codes into a family or group.
