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)
