Aeion SCM vs SAP

SAP MM/WM is a 30-year-old module in a monolithic ERP. Aeion SCM is a purpose-built supply chain platform with AI-powered forecasting, wave picking with route optimization, and voice-directed picking—all at a fraction of SAP's TCO.

Wave Picking with Route Optimization

SAP WM: Manual process

abap * SAP WM: Manual wave creation * 1. Create transfer order manually * 2. Assign stocks individually * 3. Print pick list * 4. Worker follows random path through warehouse * Average pick time: 45 minutes per wave

Aeion SCM: Automated optimization

Orders are batched into a pick wave, and each line automatically resolves to a bin location and gets a 4-character voice confirmation code. The wave is then re-sorted by aisle, then rack, then level — eliminating the backtracking that comes from picking in order-received sequence.

Bin Code Format: A-03-2aisle-rack-level (aisle A, rack 3, level 2)

Results:

  • Faster pick times
  • Reduced travel distance
  • Low pick error rate

Bin Slotting Optimization

SAP WM: Manual configuration

abap * SAP: Manual bin assignment * 1. Run LS26 (stock overview) * 2. Export to Excel * 3. Calculate ABC classification manually * 4. Update bin assignments one by one * 5. No automated suggestions

Aeion SCM: ABC-velocity optimization

Bin reassignments are suggested automatically based on each product's ABC classification and velocity:

  • A items — top 80% of value (~20% of items) → closest bins (<50 ft from dock)
  • B items — next 15% of value (~30% of items) → middle bins (50-200 ft)
  • C items — bottom 5% of value (~50% of items) → farthest bins (>200 ft)

A suggestion looks like: _Widget Pro, currently in bin C-15-3, should move to A-02-1 — "A-item → fast-pick zone."_

Slotting Results:

  • Reduced pick travel
  • Increased warehouse capacity
  • Reduced picker fatigue

Vendor Scorecard

SAP MM: Basic PO history

abap * SAP: PO history only * ME2M - Purchase Orders by Material * ME2L - Purchase Orders by Vendor * No automated scoring * Manual analysis required

Aeion SCM: Auto scorecard

Every vendor gets an on-time delivery percentage (POs received by their expected date), a quality score (based on rejection rate at receiving), a cost rank relative to other vendors for the same product, lead time and consistency, and an overall weighted score — recalculated automatically on every PO receipt, with no manual analysis required.

Vendor Scorecard Dashboard:

typescript { "vendorId": "vendor-acme", "period": "last_90_days", "metrics": { "onTimeDelivery": 92, // 92% on-time "qualityScore": 98, // 98% accepted "avgLeadTime": 6.5, // Days "leadTimeVariance": 1.2, // Standard deviation }, "overallScore": 95, "tier": "preferred", // tiered: preferred, standard, probation "recommendations": [ "Consider volume discounts at 10,000+ units/month", "Lead time consistency excellent" ] }

Procurement Workflow

SAP MM: Complex configuration

abap * SAP MM: Complex PO workflow * 1. Define purchasing organization (OX09) * 2. Define purchasing group (OPGH) * 3. Create info record (ME11) * 4. Create source list (ME01) * 5. Create purchase requisition (ME51) * 6. Convert to PO (ME21N) * 7. Configure release strategy (OME4) * 8. Configure output determination (MN04) * Total setup: 4-6 weeks

Aeion SCM: Simple, opinionated

POs get an auto-generated number ("PO-1001") and line totals calculate automatically, including any per-line discount. When a shipment is received, Aeion SCM automatically creates the corresponding inventory movement, updates each line's received quantity, and scores the vendor based on delivery timeliness — no separate manual steps.

PO Status Flow: draft → sent → partial → received

Receiving Creates Inventory Movements:

On receipt, Aeion SCM automatically:

  1. Creates an inventory movement (type: "receipt")
  2. Updates stock levels
  3. Updates the PO line's received quantity
  4. Recalculates the vendor's score
  5. Triggers a completion event your integrations can subscribe to

FAQ

Recent periods are weighted higher (about 78% of total weight falls in the most recent 6 periods). SAP's basic moving average gives equal weight to all periods. WMA captures trends significantly better.

Pick lines are automatically sorted by aisle → rack → level, using bin codes like "A-03-2" (aisle A, rack 3, level 2). Eliminates backtracking. Result: faster picking.

4-character codes drawn from a set that excludes I/O/0/1. Worker says "X7K2" to confirm a pick. Over 1 million possible combinations, chosen specifically to avoid voice recognition confusion.

SAP uses a static reorder point (manual entry). Aeion calculates a dynamic safety-stock buffer from average daily demand and your configured safety-stock days, targeting a 95% service level that accounts for demand variability.

SAP requires manual analysis of purchasing reports. Aeion auto-calculates on-time %, quality (rejection rate), lead time variance, and response time into a weighted composite score, updated on every PO receipt.

SAP: 12-18 months. Aeion: 4-8 weeks. 95% faster due to pre-configured best practices, cloud-native architecture, and opinionated workflows.

Year 1: Save ~$2,245,012 (SAP $2.275M vs Aeion $30K). Ongoing: Save ~$240,000/year in licensing + $150,000/year in basis consultant.

Yes. Export from SAP via SE16/MM01/MK01, transform to Aeion format, import. Products, vendors, inventory, POs, receipts all transfer.

Import as draft or approved status. Continue receiving in Aeion. Historical receipts import with movement history.

SAP: 50+ transaction codes, complex release strategies. Aeion: simple status flow (draft → sent → partial → received). Auto-numbering, auto-inventory on receipt, auto-vendor scoring.
