Now, let’s begin our tutorial on using SAP transaction MD01.

What is SAP Transaction MD01?

SAP Transaction MD01 (Material Requirements Planning) is a key transaction code used in SAP MM for planning material requirements based on demand and supply. It allows users to generate procurement proposals for materials, ensuring timely availability of required materials and optimizing inventory levels. With MD01, you can plan and manage the procurement process effectively, streamlining your supply chain operations.

Step 1: Accessing SAP Transaction MD01

To start using MD01, follow these steps:

1. Log in to your SAP system using your user ID and password.
2. Launch the SAP Easy Access Menu.
3. Navigate to the “Logistics” folder and expand it.
4. Locate and click on the “Materials Management” folder.
5. From the sub-menu, select “Material Requirements Planning.”
6. Next, choose “MD01 – Single-Item, Single-Level.”

Step 2: Understanding MD01 Transaction Screen

Once you have accessed MD01, you will encounter the MD01 transaction screen, which consists of various fields and tabs. Let’s explore each of them:

• Selection Criteria: This section allows you to define the planning parameters such as material, plant, and planning horizon. You can specify the required inputs to generate the procurement proposals.
• Planning Parameters: Here, you can set additional parameters for the planning run, such as safety stock, lot size, and scheduling margin key. These parameters determine how the system calculates the procurement quantities.
• Display Options: This tab provides options to customize the display of the planning results, such as sorting sequence, grouping criteria, and layout settings.
• Planning Results: The planning results tab displays the generated procurement proposals based on the selected criteria. It shows the planned order quantities, dates, and other relevant information.
• Additional Tabs: MD01 also offers additional tabs for detailed analysis and evaluation of the planning results, such as stock/requirements list, individual/cumulative requirements, and capacity load.

Step 3: Performing Material Requirements Planning with MD01

Material Requirements Planning (MRP) is a crucial process in supply chain management. Here’s how you can perform material requirements planning using MD01:

1. Start by filling in the necessary fields in the “Selection Criteria” section:

   • Material: Enter the material code for which you want to generate procurement proposals.
   • Plant: Select the plant for which you want to plan material requirements.
   • Planning Horizon: Specify the planning period or the date range for which you want to generate procurement proposals.

2. Move to the “Planning Parameters” tab and set the relevant parameters for the planning run:

   • Safety Stock: Enter the desired safety stock level for the material.
   • Lot Size: Choose the appropriate lot size calculation method, such as fixed lot size, periodic lot size, or dynamic lot size.
   • Scheduling Margin Key: Define the scheduling margin key to consider lead times and other factors when calculating the procurement quantities.

3. Once you have entered all the necessary information, click on the “Execute” button to start the material requirements planning run.

Congratulations! You have successfully performed material requirements planning using SAP transaction MD01.

Step 4: Exploring Additional Functionality

SAP transaction MD01 offers various additional functionalities to enhance your material requirements planning process. Here are some notable features you can leverage:

• MRP List: Use MD01 to display the MRP list, which provides an overview of the planned orders, purchase requisitions, and other procurement proposals generated by the planning run. This list allows you to review and analyze the planning results in detail.
• Exception Messages: MD01 generates exception messages to highlight any issues or deviations in the planning results. These messages help you identify and resolve potential supply chain problems, such as stockouts or excess inventory.
• Planning Evaluation: MD01 offers various evaluation reports and tools to analyze the planning results and monitor the performance of your material requirements planning process. These reports provide insights into the material availability, stock coverage, and other key metrics.
• Simulation Mode: You can run MD01 in simulation mode to test different planning scenarios and evaluate their impact on the procurement proposals. This feature allows you to fine-tune your planning parameters and optimize your material requirements planning process.
