A customer sets up BOM Mapping for a Configuration model using a single simple Table-Based BOM Mapping Configuration rule, as well as the BOM Item Definition and BOM Item Mapping Tables. When reviewing their implementation, they notice the following:
* The BOM Root Items Administration List shows the root BOM item and its child BOM items correctly.
No errors are displayed.
* The BOM Item Mapping Administration List shows no root BOM item or child BOM items. No errors are displayed.
Which field have they incorrectly populated in their BOM Mapping Tables?
