SAP SD and MM Integration: Stock and Availability Check in SAP SD

SAP SD (Sales and Distribution) and SAP MM (Materials Management) are tightly integrated modules within SAP. This integration ensures smooth business operations by linking sales processes with inventory and procurement processes. One of the key features of this integration is the Stock and Availability Check, which helps in determining whether the requested goods can be delivered on time. This tutorial provides an overview of the concept and a step-by-step guide with a real-world example.

Overview of Stock and Availability Check

The stock and availability check ensures that when a sales order is created in SAP SD, the system verifies the stock levels and checks whether the requested quantity of goods is available for delivery on the required date. If the stock is insufficient, SAP can suggest alternatives such as partial delivery or procurement.

This functionality is directly dependent on the material data in SAP MM and the configuration of availability checking in the system. The check is performed based on predefined rules and involves the following:

  • Stock levels in the plant.
  • Incoming and outgoing stock movements.
  • Replenishment lead times.

Step-by-Step Guide to Stock and Availability Check

Step 1: Configuration of Availability Check

  1. Navigate to the SAP Customizing Implementation Guide using transaction SPRO.
  2. Select Sales and Distribution > Basic Functions > Availability Check and Transfer of Requirements > Availability Check.
  3. Define the Availability Check settings by configuring:
    • Checking group (e.g., daily requirements).
    • Checking rule (e.g., for sales order).
    • Scope of check (e.g., include stock, production orders, and purchase orders).
  4. Save your settings to activate the availability check for the relevant material types and sales document types.

Step 2: Create a Sales Order

  1. Go to transaction VA01 to create a sales order.
  2. Select the appropriate sales document type, such as OR (standard order).
  3. Enter the Sold-to Party (customer) and Ship-to Party details.
  4. In the item overview, enter the Material and Quantity for the order.
  5. Press Enter. The system will automatically trigger the stock and availability check.

Step 3: Review the Availability Check Results

  1. After entering the material and quantity, the system displays the results of the availability check. This includes:
    • Available stock.
    • Confirmed quantity.
    • Delivery dates based on stock levels and replenishment lead times.
  2. If the requested quantity is not available, the system may suggest:
    • Partial delivery.
    • Later delivery dates.
    • Backorder processing.
  3. Confirm the proposed schedule or adjust the order quantity as needed.

Step 4: Save the Sales Order

Once the stock and availability check is complete, review all details in the sales order, including the confirmed quantity and delivery dates. Click Save to create the sales order.

Real-World Example of Stock and Availability Check

Let’s consider a scenario where a customer places an order for 500 units of a product:

  • The sales representative creates a sales order for 500 units of Material A.
  • The system performs an availability check and finds that:
    • Current stock: 300 units.
    • Planned replenishment: 200 units arriving in 3 days.
  • The system proposes:
    • Delivering 300 units immediately.
    • Delivering the remaining 200 units after 3 days.
  • The customer agrees to the proposal, and the order is saved with two delivery dates.

Benefits of Stock and Availability Check

  • Improves customer satisfaction by providing accurate delivery dates.
  • Reduces the risk of overcommitting stock.
  • Enables efficient inventory management through integration with SAP MM.

Conclusion

The stock and availability check is a vital feature of SAP SD and MM integration. It ensures that sales orders are processed based on real-time stock data and replenishment schedules, enabling businesses to fulfill customer orders effectively. By following the steps outlined in this tutorial, you can successfully configure and execute stock and availability checks in SAP SD.
