Business Central ships a flat Production BOM card and a separate "BOM" cost report, but it gives manufacturing teams no single place to see a deep product structure — to expand level 3 under level 2 under the finished good, watch the cost accumulate, and ask "can I actually build 200 of these today?" without bouncing between Item Availability, the Production BOM, and routing pages. This extension closes that gap.

Multi-Level BOM Viewer & Manager is an AL extension that adds an indented, fully drillable tree of every Production BOM and its routing — exploding each component down through sub-assemblies to raw material, with cost roll-up, margin, and live availability shown at every node. Engineers get where-used (implosion) and component-explosion in one place, plus a "can-build" calculator that walks the structure against current inventory, scheduled receipts, and demand to tell you the realistic buildable quantity and the first blocking component.

Because every business runs Business Central differently — different costing methods, unit-of-measure conventions, variant usage, and reporting needs — we do not sell this as a one-size AppSource download. ECOSIRE builds it to your environment, installs it as a per-tenant extension (no source handed to a third party, no AppSource validation delays), wires it to your permission sets, and supports it. You get a clean, upgrade-safe extension that uses table/page extensions and event subscribers rather than modifying base objects, so it survives Microsoft's monthly and major BC updates.

This is the honest version of "BOM visibility": real AL engineering on your tenant, a fixed one-time build price, and a named team that maintains it.
