| Effectivity unitsAn effectivity unit is a code that can be linked to an end item.
The effectivity unit identifies the item, and can also represent deviation(s)
from the standard end item. You can link an effectivity unit to manufactured
items and purchased items. The changes that effectivity units represent can occur in
the: - Engineering bill of material (E-BOM)
- Production bill of material (P-BOM)
- Routing
- Routing operations
- Item – supplier data
- Sources of supply strategy
Deviations can be: - The use of one component instead of another. This affects the
E-BOM or he P-BOM in Manufacturing. For example, a touring car, which is
completely standard, must be fitted with red seats instead of blue
ones.
- The way the end item is produced. This affects the routing or
the routing operations in the Routing module of Manufacturing. For example,
if you want to test a new production technique, which affects the routing or
some of the routing operations, but the result is a standard item. In this
case, unit effectivity only relates to the routing.
- The origin of the end item's parts. This affects the sourcing
strategies defined in Enterprise Planning. For example, if you want to test the components that are
supplied by a new manufacturer.
If you use unit effectivity during the design and/or
engineering phases, the resulting end items must be lot-controlled. The items
can also be serialized items. Component items (material), do not need to be
lot-controlled. However, if you want to distinguish items by effectivity unit
in the warehouse, also material needs to be lot-controlled. | |
