Engineering Change Management (LO-ECH)

Group of values assigned to specific effectivity parameters.

To process an object with a change number using parameter effectivity, you have to valuate the effectivity parameters defined in your system:

• If you want to produce a product, you use a parameter variant, in which each effectivtiy parameter is assigned exactly one value. You then get a precise specification of your product.
• If you process objects (BOMs, routings and so on) in the Engineering Workbench, you use a parameter variant to select your worklist or to filter the worklist.

Example

You produce a product for two different customers. For each customer you stamp a different logo on the casing. You created an effectivity type CUSTO with the effectivity parameter CT. Furthermore, you have created two change numbers with the effectivity type KUNDE: AE1 and AE2.

In the change number AE1 you have valuated the effectivity parameter KD with "CUSTO1", in the change number AE2 with "CUSTO2". In the BOM for the product you have created the component CASING once with the change number AE1 and once with the change number AE2. If you create a customer order, the system asks you to valuate the effectivity parameter, that means that you have to enter for which customer the product is being produced for.
