1. MRP (Material Requirements Planning)

Planning Run

• MD01 (ECC / S/4HANA): classic MRP run → plant-level or single material
• MD01N (S/4HANA): MRP Live → HANA-optimized, faster, recommended
• MD02: single-item, multi-level MRP (for testing / selective re-planning)
• MD03: single-item, single-level

MRP Types (Material Master MRP 1 view)

| Type | Description | |------|-------------| | PD | MRP — demand-driven (standard) | | VB | Manual reorder point | | VM | Automatic reorder point | | ND | No MRP | | MF | Make-to-order (individual requirements) |

Lot Sizing Procedures

| Key | Description | |-----|-------------| | EX | Lot-for-lot (exact demand quantity) | | FX | Fixed lot size | | WB | Weekly lot size | | MB | Monthly lot size | | HB | Replenishment up to maximum stock level |

Exception Messages (MD04)

| Exception | Meaning | Action | |-----------|---------|--------| | 10 | Reschedule in | Move order earlier | | 15 | Reschedule out | Push order later | | 20 | Firm planned order — reschedule | Evaluate manually | | 25 | Surplus | Cancel or reduce | | 30 | New order required | Convert planned order |

2. Production Order

Lifecycle

CO01 (Create) → Release (CO02 / KOAB batch) → Goods Issue (MIGO 261)
→ Confirmation (CO11N) → Final Confirmation → TECO (technically complete)
→ Settlement (KO88) → CLSD (closed)

Key T-codes

| T-code | Description | |--------|-------------| | CO01 | Create production order | | CO02 | Change production order | | CO03 | Display production order | | CO11N | Production order confirmation | | CO13 | Cancel confirmation | | CO24 | Missing parts list (component shortage) | | COOIS | Production order information system | | MIGO | Goods issue (261) / GR (101) for order |

Goods Issue

• Manual: MIGO → movement type 261 → production order number
• Backflush: CO11N → backflush checkbox → automatic at confirmation
• Partial GI: allowed — tracks remaining requirements in MD04

Settlement

• KO88: individual order → settlement to: cost center / G/L / material (product cost collector)
• KO8G: collective settlement → mass processing
• Always simulate first → check receivers and amounts before actual posting
• Variance categories: input price / input quantity / output price / output quantity / remaining input

3. Process Orders (PP-PI)

Used in: chemical, pharmaceutical, food & beverage industries

| T-code | Description | |--------|-------------| | COR1 | Create process order | | COR2 | Change process order | | COR6N | Process order confirmation | | CORK | PI sheet (process instruction) execution | | CORZ | Process order scheduling |

Process instructions (PI sheets): define what operators enter during production Master recipe (C201): replaces routing for process industries

4. BOM Management

Key T-codes

| T-code | Description | |--------|-------------| | CS01 | Create BOM | | CS02 | Change BOM | | CS03 | Display BOM | | CS11 | BOM explosion (multi-level) | | CS14 | BOM comparison | | CS15 | Where-used list |

BOM Usages

| Usage | Description | |-------|-------------| | 1 | Production | | 2 | Engineering / design | | 3 | Universal | | 5 | Sales | | 6 | Costing |

• Alternative BOMs: same material, multiple production methods (alt. 1, 2, 3...)
• Selection method: MRP 4 view → BOM explosion / selection method

---

5. Routing and Work Centers

Work Center (CR01 / CR02)

• Define: capacity category, available capacity, costing formulas, scheduling formulas
• Capacity: CR11 → available capacity per shift (machine / labor)

Routing (CA01 / CA03)

• Operations: sequence → work center → standard values (setup / machine / labor time)
• Control key: determines: confirmation required / goods movement / costing / scheduling

Reference Operation Sets (CA11)

• Reusable operation templates → assign to multiple routings

---

6. Capacity Planning

| T-code | Description | |--------|-------------| | CM01 | Capacity load overview (work center) | | CM21 | Capacity leveling (interactive) | | CM50 | Variable capacity planning | | CM99 | Scheduling overview |

• Finite scheduling: material's MRP considers capacity constraints
• Infinite scheduling: MRP ignores capacity → capacity leveling done separately
• Bottleneck analysis: CM50 → identify overloaded work centers

---

7. Demand Management

• MD61: planned independent requirements (make-to-stock strategy)
• MD62: change planned independent requirements
• Strategy group (MRP 3 view): determines how sales orders consume PIRs
• Strategy 10: make-to-stock (no individual requirements)
• Strategy 20: make-to-order (each order = separate production)
• Strategy 40: planning with final assembly

---

8. S/4HANA PP Changes

| Feature | ECC | S/4HANA | |---------|-----|---------| | MRP run | MD01 | MD01N (MRP Live) recommended | | MRP performance | Slower (sequential) | Parallel HANA-based | | Exception handling | MD04 list | Enhanced exception management | | Scheduling board | CM21 | Production Scheduling Board (Fiori) | | Shop floor | COOIS | Manufacturing Execution Fiori apps | | eWM integration | External WM | Embedded eWM (same system) | | pMRP | Not available | Predictive MRP (AI-based exception detection) |
