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

What is SAP Transaction JBRX?

SAP Transaction JBRX (Material Requirements Planning) is a critical transaction code used in SAP MM to generate and manage material requirements for production planning and procurement. It allows users to run MRP calculations, analyze material requirements, and create procurement proposals to ensure an uninterrupted supply of materials for production and sales processes.

Step 1: Accessing SAP Transaction JBRX

To start using JBRX, follow these steps:

1. Login 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” and then choose “Material Requirements Planning” again to proceed to the JBRX transaction.

Step 2: Understanding JBRX Transaction Screen

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

• Planning Parameters: In this section, you can define the planning parameters for MRP runs, such as the planning horizon, scheduling type, and MRP controller.
• Selection Parameters: Here, you can specify the selection criteria for material requirements planning, such as material group, plant, and storage location.
• Planning Result: This tab displays the results of the MRP calculation, providing an overview of the material requirements and procurement proposals based on the defined parameters.
• MRP List: The MRP list tab shows a detailed list of material requirements and procurement proposals, allowing you to analyze and manage them effectively.
• Planning Log: In this tab, you can view the log of the MRP run, which provides information on any errors, warnings, or information messages generated during the planning process.

Step 3: Running Material Requirements Planning with JBRX

To run material requirements planning using JBRX, follow these steps:

1. Start by filling in the necessary planning parameters in the “Planning Parameters” section:

   • Planning Horizon: Define the time range for the MRP calculation, specifying the start and end dates.
   • Scheduling Type: Select the appropriate scheduling type, such as forward, backward, or net change.
   • MRP Controller: Choose the MRP controller responsible for the material requirements planning process.

2. Move to the “Selection Parameters” tab and enter the relevant criteria for material selection, such as material group, plant, and storage location.
3. Click on the “Execute” button to start the MRP run.
4. Once the MRP calculation is complete, navigate to the “Planning Result” tab to view the material requirements and procurement proposals generated.
5. Analyze the results in the “MRP List” tab and take appropriate actions, such as creating purchase requisitions or planned orders, to fulfill the material requirements.

Congratulations! You have successfully run material requirements planning using SAP transaction JBRX.

Step 4: Leveraging Additional Functionality

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

• Change Planning Parameters: JBRX allows you to modify the planning parameters for MRP runs. You can adjust the planning horizon, scheduling type, or MRP controller to fine-tune your material requirements planning process.
• Display Planning Results: Use JBRX to display the results of past MRP runs by entering relevant selection criteria. This enables you to review previous material requirements and procurement proposals for analysis and tracking purposes.
• Simulation Mode: JBRX offers a simulation mode, allowing you to perform “what-if” scenarios for material requirements planning. You can simulate different planning parameters and analyze the impact on material requirements and procurement proposals before executing them in the live system.
• Mass Processing: If you have a large number of materials to process, JBRX provides mass processing functionality. This allows you to run MRP calculations and generate procurement proposals for multiple materials simultaneously, saving time and effort.
