Recursiveness Check
A BOM is recursive if the product contains a component with the same object number as the superior assembly. This is often due to input errors, but in individual cases it may be intentional.
Example
A component has the same material number as a higher-level product. In paint production, a residual quantity of the paint to be produced is used as a component.
The figure below shows the repeated explosion of an object within an explosion path (recursiveness).
Recursiveness check within a BOM group
The recursiveness check includes all BOMs in a BOM group. For example, the system finds recursiveness in a variant BOM, even if an individual variant is not recursive.
Example
A variant BOM has 2 variants:
The first variant for material A has the following material components:
Item 0010 with material B
Item 0020 with material C
The second variant for material B has the following material components:
Item 0010 with material A
Item 0020 with material C
Neither variant is recursive. However, the system finds the following material components to be recursive:
In variant for material A : item 0010 with material B
In variant for material B : item 0010 with material A
BOM explosion for recursive BOMs
BOM explosions stop at the component that causes recursiveness.
