# How to find matching level 2 asset for each level using a Parent/child relationship/structure

#### broken keyboard

##### New Member
Hi all,

I am trying to locate the "level 2" asset of each asset number in the list in Column A. A parent/child relationship is shown in Columns F & G. Not sure what the best formula to use here would be, but maybe an array? Not every asset in the hierarchy has an immediate next-level up asset associated. So, for example, an asset at level 7 may have a parent at level 3, then the level 3 asset would have a parent at level 2. The asset at level 2 is the asset I need to return. Any help on the below is much appreciated

Why does 9 mean SUM in SUBTOTAL?
It is because Sum is the 9th alphabetically in Average, Count, CountA, Max, Min, Product, StDev.S, StDev.P, Sum, VAR.S, VAR.P.

This isn't pretty, but I think it works. This approach uses help columns H:AC (or AE if you want to shorten a formula) to examine every parent-child relationship and build the multigenerational lineup on a single row. So columns H:L begin with the question "Does the Parent appear as a Child, and if so, what is its Parent?" to go in one direction, with each column to the right referring to its neighbor at left. The formula to do that is pulled to the right until only blanks are generated for all of the rows. Columns M:Q ask a similar question, "Does the Child appear as Parent, and if so, what is it's Child?" to go in the other direction. Again, that formula is pulled to the right until only blanks are generated. Then columns R:AC perform a look up using columns A:B to create a hierarchy mapping for every item in the parent-child multigenerational table. Finally, we return to column A, and for every asset number, we search the multigeneration table (F3:Q21) to find that asset, determine what row in the table it is found (any row where it is found should be fine, but the first is taken), and then we look across that row to find which asset in its family line corresponds to hierarchy level "2". I've separately tabulated the row and column index numbers within F3:Q21 where this occurs, as shown in columns AD:AE, but those same formulas are incorporated in the INDEX formula in column C. If you prefer, the column C formula could be shortened substantially by simply referring to the value in columns AD and AE.
