Replacing a single row in a table with multiple related values

[danbtaylor]

I am trying to break down the following 2-column table to include only each 'FinishedGood' and all its 'Inventory Parts' broken down to the 'Component' level. I want to replace each 'SubAssembly' Inventory Part with its corresponding 'Components':

Source Format:

Assembly Item	Inventory Part
FinishedGood1	Component1
FinishedGood1	SubAssembly1
SubAssembly1	Component2
SubAssembly1	Component3
SubAssembly1	Component4
SubAssembly1	SubSubAssembly1
SubSubAssembly1	Component5
SubSubAssembly1	Component6

<tbody>
</tbody>

Desired Format:

Assembly Item	Inventory Part
FinishedGood1	Component1
FinishedGood1	Component2
FinishedGood1	Component3
FinishedGood1	Component4
FinishedGood1	Component5
FinishedGood1	Component6

<tbody>
</tbody>

A FinishedGood may be comprised of a SubAssembly, a Component, another FinishedGood, or any combination of such. A SubAssembly may be part of multiple distinct FinishedGoods, and a component may be part of multiple distinct SubAssemblies

This information changes daily, and is updated through an ODBC data source, so automating the process is crucial.

I've tried creating separate tables for each stage, i.e., FinishedGoods, SubAssembly, etc., and relating them, however I've had no luck. I've also tried SQL queries to no avail.
