Manufacturers who service their own installed equipment usually run two disconnected worlds: production and inventory live in Business Central, while technicians, work orders and assets live in Dynamics 365 Field Service / CE on Dataverse. The result is re-keyed serials, guessed warranties, and spare parts that exist in the ERP but never reach the technician.

This extension closes that loop. ECOSIRE builds you a per-tenant AL extension on your Business Central environment that synchronizes the manufacturing context Field Service needs and writes service outcomes back into BC.

What it does: - Pushes as-built BOMs and serial/lot numbers from finished production orders into Field Service customer assets, so the technician sees the exact configuration shipped. - Tracks warranty and entitlement by serial number, derived from the production/sales date, so in-warranty vs. billable is decided automatically. - Links spare-parts inventory in BC items and locations to Field Service products, so parts availability and consumption are real, not estimated. - Creates a service-to-manufacturing return loop: a field replacement raises the matching return/repair document in BC. - Maintains an installed-base asset history that both systems can read.

Technically: AL table and page extensions surface the new fields and FactBoxes; event subscribers fire on production-order finish and posting; integration runs through the Dataverse virtual-tables / Business Central API (OData v4) rather than brittle CSV jobs; sync is scheduled on the BC job queue; access is governed by dedicated permission sets.

This is build-to-order, not an instant AppSource download. ECOSIRE scopes it to your entity mapping, builds it, installs it as a per-tenant extension, and supports it on your tenant.
