Starting with this Single Level BOM table (Windows 7 Pro, Excel 2013). "Qty Per" refers to the quantity of the child needed in the Parent:

ParentChildQty Per
PART-APART-A11
PART-APART-A11215
PART-APART-A22
PART-APART-A2224

I need (a Macro) to generate the exploded (or stacked) table below. As an example doing this manually for the Grand Child, the process went like this:

1. For each single level BOM Parent/Child row (R), find # grand children rows (N)
2. Copy entire row (R) and insert N-1 copies below row R (Note: if N=1, no copy/insert is required)
3. Find grand child(ren) for each child and corresponding Qty Per in the single level BOM Table and copy/paste into Grand Child / Grand Child Qty per columns
4. Repeat steps 1-3 for Great Grand Children and Great Great Grand Children


Parent
Child
Child Qty Per
Grand Child
Grand Child Qty per
Great Grand Child
Great Grand Child Qty Per
Great Great Grand Child
Great Great Grand Child Qty Per
