The valuation structure is oneof the attributes of an item cost profile which isused to cost inventory items. However, conflicts may arise if thecosting attributes in the valuation structure don't match the inventoryattributes of the inventory items.
Valuation Structure Conflict Resolution
In cases where the valuation structure containsa costing attribute that's missing on the item, the cost processorapplies these rules:
-
If the costing attribute is mandatory,then the association of the valuation structure to the item is disallowed.
-
If the costing attribute is optional,then the association of the valuation structure is allowed, and thevaluation unit will have a Null value for the costing attribute.
For example, an item isn't lot enabled, but Lot isa costing attribute in the valuation structure. In this case, if theLot costing attribute isn't mandatory, the valuation structure isconsidered valid for the item, and the processor applies Null to thelot value. However, if the attribute is mandatory, the valuation structureis considered invalid.
A costing attribute can be changed from mandatoryto optional at any time to accommodate missing values. However, itcan't be changed from optional to mandatory, if any transaction usingthat valuation structure has been processed.
