The override pricing feature in SouthWare uses a hierarchy to determine which override to use if multiple overrides could apply to the same item. In the Inventory / Sales control record (IS0802 #22) you specify which override types you use. These are listed in the default sequence they are applied, typically most specific (customer / item) to least specific (product category).
You now have the ability to modify the hierarchy sequence for the override pricing methods you use. This can allow you to set up override pricing in the most efficient manner for your situation and ensure that the overrides are applied in the hierarchy sequence needed.
