3. Inventory Optimization:
Monitors stock levels, safety stock, and lead times to prevent overstocking.
4. Production Planning:
Determines when and how much to produce or procure.
5. Scheduling:
Calculates order start and finish dates based on material availability and lead times.
Inputs to MRP:
Bill of Materials (BOM) – List of components required.
Material Master Data – Includes planning parameters (MRP type, lot size, lead time).
Inventory Levels – Current stock and open orders.
Demand Data – Sales orders, forecasts, and planned independent requirements (PIR).
Outputs of MRP:
Purchase Requisitions (PR) – For externally procured materials.
Planned Orders – For in-house production.
Rescheduling Proposals – To expedite or delay existing orders.
Common T-codes:
MD01 → Total Planning for a Plant
MD02 → Single Item, Multi-Level Planning
MD04 → Stock/Requirements List
MD05 → MRP List
Formula:
Material Requirement = (Gross Requirement – Available Stock – Scheduled Receipts)
Example:
If a production order for 100 pumps is planned and only 60 casings are in stock, MRP automatically generates a Purchase Requisition for 40 casings.

Q: What is a Release Strategy in SAP?
Answer:
A Release Strategy in SAP defines the approval workflow for purchasing documents, ensuring controlled, policy-based, and auditable procurement decisions, thereby improving accountability and compliance within the organization.
Definition:
A Release Strategy in SAP is a structured approval process used for purchasing documents such as Purchase Requisitions (PR) and Purchase Orders (PO).
It ensures that procurement decisions are reviewed and authorized by the appropriate personnel before the document is processed further.
Purpose:
To maintain control, transparency, and authorization in the procurement process.
To prevent unauthorized or incorrect purchases.
To standardize approval workflows based on company policies.
Key Features:
1. Document Control:
Allows certain purchasing documents to be approved in stages before execution.
2. Condition-Based Approval:
Release strategy is determined by criteria such as material group, value, plant, or purchasing organization.
3. Multi-Level Approval:
Supports single or multiple release levels, e.g., Engineer → Manager → Finance Head.
4. Integration:
Applicable for Purchase Requisitions (PRs), Purchase Orders (POs), and Contracts in Material Management (MM).
5. Status Control:
A document can be in statuses such as Blocked, Released, or Partially Released depending on the approval stage.
Release Strategy Components:
Release Group: Defines the document type (e.g., PR or PO).
Release Codes: Represent individual approvers or authorization levels.
Release Indicator: Shows the document status (e.g., Released or Blocked).
Release Conditions: Define criteria that trigger the release strategy (e.g., value > ₹1,00,000).
Classification System: Used to assign characteristics (like value, plant) to determine release conditions.
Example:
A Purchase Requisition over ₹5,00,000 may require approval from:
1. Purchase Officer → Release Code A
2. Purchase Manager → Release Code B
3. Finance Head → Release Code C
The document can only be converted to a PO after all approvals (releases) are completed.
Formula:
Release Strategy = f (Document Type + Value + Approval Levels + Conditions)
