Detecting Loops in Bill of Material
When you calculate cost prices and material requirements, LN checks multilevel bills of material for loops. You are therefore advised to run this session regularly, as it allows you to correct incorrect data at an early stage.
Example
Manufactured item A is made up of purchased part B and manufactured item C. Manufactured item C in turn consists of manufactured item A and purchased part E.
| A | Wheel |
| B | Rim |
| C | Hub |
| E | Ball bearing |
| L1, L2, L3 | Level 1, 2, 3 |
The loop is A-C-A
