Electrical Equipment
Electrical Equipment: production orders and BOM, stock and warehouse, quality and reporting.
Challenges
- Serial numbers are not tracked, so warranty coverage cannot be confirmed from the sales invoice.
- Type tests and the CE technical file are scattered, so documents are hunted for during audits.
- Nobody knows which batch a returned unit came from, so the root cause stays hidden.
- Spare-part stock is not linked to the bill of materials, so service jobs sit waiting.
Workflows
From production to serial number
- The production order is opened against a revision-controlled bill of materials.
- Assembly and test operations are tracked at the work center.
- Every unit gets a serial number and is received into stock with its batch data.
From sale to warranty service
- The serial number is recorded on the sales invoice and the warranty start date is set.
- The service request is opened by serial number and warranty coverage appears automatically.
- Spare parts used are deducted from stock and the fault cause is recorded.

FAQ
Can I look up warranty by serial number?
Yes — the serial number on the sales invoice sets the warranty start, and coverage shows on the service screen.
Can I attach the CE technical file to the product?
Yes — type tests and conformity certificates are stored in the document archive on the product card.
Can I find the batch of a faulty unit?
Yes — the serial number is tied to its production batch and every other unit from that batch is listed.
Can I pull spare parts straight from the bill of materials?
Yes — on the service form you pick parts from the bill of materials and they are deducted from stock.
Can I track product revisions separately?
Yes — the bill of materials is versioned, and which serial was built to which revision is on record.
