Relate primary key to multiple columns

[Anonymous]

I have three data tables that look like this:

I have many visuals/charts/tables that center around ItemTable and use ItemTable as a filter.

Right now, I have ItemTable related directly ProblemLog by Item -- so if I filter to A1 from ItemTable, I just see Problem #1. This is a 1:Many relationship (can have multiple problems for one item).

The challenge I have is taking into account the ParentChild table. When I filter ItemTable to A1, I'd like to see the Problems for A1 and all of its children. So when filtering for A1, I need to see Problem #1 and Problem #3, because D4 is a child of A1.

Does anyone have a thought on how to set up relationships with the ParentChild table?

It's almost like I need the relationships set up like this, though I don't think this would actually work since there can only be one active relationship:

Update, solved this, here's the simplified solution for anyone searching in the future:

I manipulated my ParentChild table to take this format, then was able to relate ItemTable to ParentChild to ProblemLog.

Hi @parry2k -- thanks, this is the almost exact approach I used.

I actually created 4 separate queries for each "child" level and then appended the four together -- using Unpivot is much better! THANK YOU!
