Spare Parts¶

The Spare Parts module (roots_hemms_spare_parts) gives each equipment record its own spare-part template, then uses that template to pre-fill consumption pickings automatically whenever the PM cron fires — eliminating the manual step of looking up which parts a technician needs before they walk to the storeroom.

Key features¶

1. Spare-part template per equipment¶

Every equipment record gains a Spare Parts tab listing one hemms.equipment.spare.line per part. Each line stores:

• Product — storable or consumable item from the product catalogue
• Default Qty — how many to pull for a typical PM visit
• PM Kinds — optional filter: include this line only for Calibration, Safety Inspection, or General PM (leave blank to include in all)
• Position / Note — free-text reminder ("left battery bay", "filter behind front panel")
• On Hand badge — live qty_available pulled from stock, turning red when the line is critical and stock is zero

2. Auto-draft picking on PM cron¶

When a PM request is generated by the OCA maintenance cron:

1. roots_hemms_spare_parts checks whether the equipment has allow_consumptions=True AND roots_auto_generate_picking=True
2. If yes, it reads the spare-line template, filters lines by the request's maintenance_kind_id, and creates a draft Consumption picking pre-filled with all matching products at their default quantities
3. The technician only needs to review, adjust, and validate — not build the picking from scratch

3. Stock Request (SR) numbers and tracking¶

Every picking linked to a maintenance request is assigned a sequential SR number (SR/2026/00001) at creation — from the ir.sequence code hemms.stock.request. A dedicated My Open Requests menu (Maintenance → Operations → Stock Requests) gives technicians and managers a single place to track in-flight SR pickings, with progress bars showing done vs. pending lines.

Architecture¶

roots_hemms_spare_parts is a Layer 3 (hospital-lens) extension:

What it does NOT do (yet)¶

• No reorder point / MRP integration — the module flags low stock via an activity, but it does not auto-create purchase orders. Tracked on the Roadmap.
• No cost allocation by department — parts consumed are posted to the default stock valuation account. Hospital cost-centre allocation is a Q6+ item.
• No vendor catalogue per spare — the product's standard vendor is used. Restricting suppliers per equipment type is a future enhancement.
