Overview of Logistics Execution (LE) in SAP
Logistics Execution (LE) in SAP is the crucial step in bridging the gap between the receipt of materials (inbound processes) and the shipment of goods (outbound processes). LE covers the handling and management of goods receipts from vendors and goods issues for customers, ensuring that inventory, financial accounting, and order fulfillment processes are integrated and efficient.
Here’s a difference table comparing Inbound Logistics (related to vendors) and Outbound Logistics (related to customers) within the Logistics Execution (LE) processes in SAP. This table will help illustrate the key distinctions between the two processes.
| Aspect | Inbound Logistics (Vendor-Side) | Outbound Logistics (Customer-Side) |
|---|---|---|
| Process Origin | Starts with purchase order processing in Materials Management (MM). | Starts with sales order processing in Sales and Distribution (SD). |
| Document Types | Purchase Order, Inbound Delivery, Goods Receipt (GR). | Sales Order, Outbound Delivery, Goods Issue (GI). |
| Role in SAP Modules | Primarily involves MM (Materials Management), Invoice Verification. | Primarily involves SD (Sales and Distribution), FI (Financial Accounting). |
| Goods Movement | Goods are moved from the vendor’s warehouse to the company’s warehouse. | Goods are moved from the company’s warehouse to the customer’s location. |
| Goods Receipt | Goods Receipt (GR) updates inventory and stock levels in MM. | Goods Issue (GI) reduces stock levels and updates inventory in MM. |
| Inventory Impact | Increases stock levels in the company’s warehouse. | Decreases stock levels in the company’s warehouse. |
| Stock Updates | Updates inventory in Materials Management (MM) upon receipt. | Updates inventory in Materials Management (MM) after goods issue. |
| Document Control | Control of inventory at warehouse receipt. | Control of sales at customer delivery. |
| Billing | No direct billing, but Invoice Verification is required for payment processing. | Involves billing through SD once goods are delivered and PGI is completed. |
| Transportation | Inbound Shipment to the company’s warehouse. | Outbound Shipment to the customer’s delivery address. |
| Customer Impact | Impacts stock and availability for future sales orders. | Directly impacts customer orders and fulfillment. |
| Post-Process Tasks | Invoice Verification (IV) to ensure supplier invoices match the goods received. | Billing and invoicing post-GI; generates accounting entries for customer receivables. |
Summary of Key Differences:
- Inbound logistics focuses on goods coming into the company from the vendor, involving purchase orders, goods receipt, and updates to inventory. It starts in Materials Management (MM) and links to invoice verification for financial accuracy.
- Outbound logistics is concerned with shipping goods to customers, starting with sales orders, generating outbound deliveries, and posting goods issues. It affects sales operations (via SD) and inventory management (via MM), culminating in billing for the customer.
Both processes are critical for maintaining inventory accuracy, customer satisfaction, and financial integrity in SAP, with distinct workflows and SAP modules involved for each.
Inbound Logistics: Vendor-Side Processes
1. MM Ordering: Purchase Order Processing
- Purchase Order Processing in Materials Management (MM) is the process where the company issues purchase orders to vendors to procure goods.
- The purchase order contains details such as the material type, quantity, and delivery terms.
- Once the order is confirmed by the vendor, an inbound delivery is created in the system, representing the goods that are expected from the vendor.
2. Inbound Delivery
- Inbound Delivery is created in SAP after the vendor confirms shipment, based on the purchase order.
- It represents the expected goods from the vendor, including information about quantities, materials, and shipping points.
- The inbound delivery document helps track the receipt of goods and ensures they are correctly received and verified.
3. Inbound Shipment
- The inbound shipment process is triggered when goods are dispatched from the vendor’s warehouse to the company’s receiving location.
- It is linked to the inbound delivery and tracks the transportation details, shipment progress, and delivery confirmation.
- The shipment process helps ensure that the goods are transported efficiently and safely to the warehouse.
4. Goods Receipt (GR)
- Goods Receipt (GR) is the process of physically receiving the goods from the vendor.
- When goods are received in the warehouse, the system verifies them against the purchase order and inbound delivery.
- A GR document is created in SAP to update stock levels in Material Management (MM) and increase inventory.
- This process also creates an invoice verification (IV) document for matching the invoice to the received goods.
Outbound Logistics: Customer-Side Processes
5. SD Order Processing: Sales Order Processing
- Sales Order Processing in Sales and Distribution (SD) starts with receiving a customer’s order for goods or services.
- The order includes details such as the customer’s requirements, materials, quantities, and shipping instructions.
- After confirming the order, a delivery document is created to manage the outbound delivery to the customer.
6. Outbound Delivery
- Outbound Delivery is the document that facilitates the shipping of goods to the customer.
- It links the sales order with the goods issue and outlines the quantities and details to be dispatched.
- A delivery document includes information such as the shipping point, delivery date, and items to be shipped.
7. Goods Issue (GI)
- Goods Issue (GI) is the process of physically shipping goods to the customer and recording the goods movement in SAP.
- The PGI (Post Goods Issue) action updates the Materials Management (MM) module by reducing the stock quantities based on the goods shipped.
- PGI also generates accounting entries in FI (Financial Accounting) for updating customer receivables and revenue recognition.
8. Outbound Shipment
- After goods are issued, the outbound shipment process manages the transportation and movement of goods to the customer.
- The shipment includes tracking and delivery details, which help ensure that goods reach the customer on time and in good condition.
- The shipment is completed once the goods are physically delivered to the customer.
9. Billing
- Billing is the final step in the logistics execution process.
- After the goods issue is processed, the system generates a billing document for the customer, based on the delivery and sales order.
- The billing process creates an invoice, which updates the accounts receivable and records revenue in the Financial Accounting (FI) module.
Conclusion
The processes in Logistics Execution (LE) in SAP play a critical role in managing the movement of goods from suppliers to customers, ensuring that goods receipts and goods issues are properly tracked and recorded. These processes, from purchase order creation to sales order processing and goods shipment, are tightly integrated with SAP’s Materials Management (MM), Sales and Distribution (SD), and Financial Accounting (FI) modules, allowing businesses to maintain accurate records and efficient operations.
