| # Unit Effectivity La gestion par unité d'évolution est une méthode permettant de contrôler la validité des variantes d'un produit fini. Le numéro d'évolution peut servir au rattachement, ou à la modélisation d'exceptions à partir d'un produit fini standard, ce qui vous permet de créer des variantes sans avoir à définir des codes Article distincts. Il n'est alors pas nécessaire de gérer des nomenclatures distinctes pour chaque combinaison de variantes. Les produits finis peuvent être, par exemple, des avions ou des voitures de tourisme. Les écarts sont de relativement légères variantes du produit fini. Par exemple, l'installation de sièges rouges plutôt que bleus, ou la mise en place d'un système de radar ou d'air conditionné spécial, sur un avion par ailleurs de type standard. La gestion par unité d'évolution facilite l'application de modifications dans les cas suivants : peu de modifications sont effectuées ; les modifications s'appliquent à des sous-ensembles relativement petits du produit fini ; les modifications ont pour origine une demande des clients, le processus de conception ou le processus de fabrication. The main concepts in unit effectivity are: Numéros d'évolution: An effectivity unit is a code that is linked to an end item for identification, and which can represent the deviation(s) from the standard end item. You can link an effectivity unit to manufactured items and purchased items. Requirements: A requirement in unit effectivity is a business reason that you define to describe the modifications and the variations for an item (the exceptions). The requirement is expressed by exceptions, as: Requirements can indicate, for example, regulations: USA: USA regulations EUR: European regulations ASIA: Asian regulations Requirements can also, for example, concern an item’s model: LIGHT: Model with limited features NORMAL: Model with the normal features ADVANCED: Model with advanced features Exceptions: An exception in unit effectivity is the definition of a deviation that applies to a unit effective item. An exception indicates, for example, whether a specific BOM line or a specific routing operation is used for an effectivity unit. Exceptions are often created as a result of customer requirements, or technology upgrades. Impression du rattachement par numéro d'évolution (tcuef0412m000): You can use effectivity units for pegging purposes. If an effectivity unit is specified on a sales order line, Enterprise Planning provides Manufacturing, Procurement, and Warehousing with that effectivity unit. In this way you can trace a specific unit effective item. Impression de l'état d'avancement (tcuef0414m000): You can print a report that outlines the progress on PCS activities, sales order lines, installments for sales orders, purchase orders, production orders, and service order activities that are related to an effectivity unit. The progress is indicated in the status column of the report. Paramètres gestion par n° d'évolution (tcuef0100s000): You can also maintain the unit effectivity parameters. Exemple Your company produces touring cars. The standard configuration of a touring car has blue seats and air conditioning. However, some extra requirements can be built in on customer request. For example, a customer wants green seats instead of blue seats, or the customer wants a television set installed. If a customer orders two different configurations, two sales order lines must be created. An effectivity unit is generated for each sales order line, for example effectivity unit 4500 (green seats) and 4501 (television set installed). You can configure the touring car from the sales order line. Requirement GREEN SEAT is selected for 4500, and requirement TV is selected for 4501. The effectivity units are used in the order-planning engine in Enterprise Planning. During the BOM explosion in the MRP run, ERP Enterprise determines the validity of each BOM line for effectivity units 4500 and 4501. The effectivity units can be pegged to the resulting production orders and purchase orders, for all BOM levels. |
