Hi,
I have BOM table with Parent Item # & Component Item # columns.
I would like to add 'Finished Item #' column - the highest level for each component.
(I have highlighted finished items with different colors to distinguish them)

Optionally, it would be nice to have 'Relative Component Level #' column.
Any ideas how to approach this?
I don't have much experience with iterative macros and it seems that it is needed here.
