How to manage nested BOMs for custom panels

Custom facade products are nested: a panel is not one row, it is sheet, extrusions, tape, and fasteners. Spectr’s BOM management is built for unique non-serial fabrication with nested structures, cut lists, and inventory allocation tied to the project.

Key facts

Flattening everything to a shopping list hides which hardware belongs to which mark.
Nested structure is how you allocate a specific sheet to a specific cutlist.
Spectr links those structures to the project record so cost is not allocated by guess later.
Revisions should change the nest, not spawn a parallel workbook.

How shops handle this

Keep the parent as the thing you ship
The panel or unit is what the crate and the elevation care about.
Nest the cut materials underneath
Sheet and extrusion lengths belong to that parent.
Allocate inventory at the level you actually pick
Containers and remnants still need a home.
Issue only when the nest is complete enough to buy
Partial nests become partial POs and missing parts at the brake.

Common questions

Is this the same as a manufacturing BOM in SAP?

Same idea, different assumption: these parents will not be made a thousand times.

How deep should we nest?

Deep enough that purchasing and the shop do not argue. Not so deep that engineering lives in the ERP.
