Purchasing & replenishment · Auto parts distribution
Keep the right parts on the shelf.
A part supersedes and demand history doesn't follow the new SKU. The buyer over-orders the dead number or stocks out on the live one.
The reality
Supersessions break the reorder point.
The supplier issues a supersession, the old part number's velocity history sits orphaned, and the new stocking unit looks like a slow mover because it has no demand behind it. The buyer is reconciling supplier supersession bulletins against the ERP stocking file by hand while reorder points fire on numbers that no longer exist and the shelf goes empty on the parts that do.
The operator owns the stocking decision. It detects the supersession from the supplier feed, carries the demand history onto the new stocking unit, recalculates min/max against real velocity and lead time, issues the reorder PO, and flags the dead number for return — so the shelf reflects what's actually selling.
How the operator runs purchasing & replenishment
Supersession bulletin · Map
mapping- Bulletin: ACDelco PF48 → PF48E
- 12-month velocity carried to new SKU
- Old number flagged for return
01Catch the supersession
Reads the supplier supersession bulletin, maps old to new part number, and carries demand history forward.
SKU PF48E · Stocking model
calculating- Velocity: 45/mo, lead time 5 days
- Min 12 / Max 40 set
- On-hand 9 — below min, reorder triggered
02Recalculate the stocking unit
Sets min/max from real velocity and supplier lead time, accounting for seasonality on the line.
PO 44102 · Primary supplier
submitting- Reorder qty 31 to hit max
- Brought to line minimum for freight
- PO submitted — ETA 5 days
03Issue the reorder PO
Builds the PO to the primary supplier, respects line minimums, and submits for the fill.
The outcome
Buyer time on routine fills cut by half
Right parts in stock, obsolescence minimised
- Demand history follows the part through every supersession
- Reorder points fire on live numbers, not dead ones
- Buyers spend their day on obsolescence and exceptions, not routine fills
