Unit effectivity in Enterprise PlanningIn LN, you can use unit effectivity to adapt the standard business procedure for items, and model exceptions that originate from specific customer requirements. The unit effectivity concept supports situations in which customers have specific wishes concerning the features of the products they order. For each specific wish, you can define an exception, and link it to the business aspect that is impacted by the exception. In this way, you can model small deviations from the standard product configuration. LN takes into account the exceptions that you define in the process of order planning. Before you can define exceptions, you must first set up a unit effectivity structure for the item involved in the Unit Effectivity (UEF) module of Common. For more information about the use of unit effectivity, refer to online manual topic To set up unit effectivity. Next you can define exceptions for the following business aspects:
On the other hand, the way in which unit effectivity impacts on the order-planning process depends on the following criteria:
Inventory and firm-planned receipts For each requirement, LN checks the projected inventory level for the unit involved. If the inventory is insufficient, LN checks the inventory of interchangeable units, and uses this inventory when necessary. If no sufficient inventory can be found, LN looks for the first unused firm-planned receipt of the unit or any interchangeable unit. Refer to online manual topic Example: inventory usage for units (unit effectivity) for more information about interchangeable units. Generating planned orders If inventory and firm-planned receipts are not sufficient to meet a requirement, Enterprise Planning generates a planned order. As a rule, this order takes into account all demand, within the order interval, of the following units:
If the order quantity is higher than the required quantity (because of lot-size rules), LN checks if part of the order can be used for a unit with the same configuration (either within or beyond the order interval). If this is the case, the planned order contains a separate order line for this unit. Refer to online manual topic Example: planned orders for units (unit effectivity) for more information about planned orders for interchangeable units.
