Multi Level Pegging a Multi Level BOM

I’m attempting to understand the Multi-Level Pegging tables: PegLink, PegDmdMst, and PegSupMst.

Having followed both these threads:

I get how they interact with one another from a top-level aspect job “ties” to sales order. @bordway made a really good dashboard in the second post that nearly gets me where I want to be.

What I’m looking for is Multi Level Pegging but for the entirety of an exploded BOM. Some of our parts go 4 levels deep and I want to get those preceding jobs linked in on this somehow. I thought by building a recursive CTE BOM and then linking in the Pegsummary table I would be close. But now I’m stumped on how to tie up the demand and supply links, job to job, to the top-level demand, sales order.

Anyone got any pointers on what my next step is?
