Resolving the Error: “MRP Controller 001 Does Not Exist for Plant THYD”

In SAP, the error “MRP Controller 001 does not exist for plant THYD” occurs when the MRP controller (Material Requirements Planning controller) is not assigned or configured for the specified plant. This tutorial walks you through the steps to resolve the issue and ensure the MRP controller is correctly configured.

What Is an MRP Controller?

An MRP Controller is responsible for overseeing material planning and procurement processes in SAP. Each MRP controller is assigned to specific plants to manage materials effectively. If the controller is not set up for a plant, the system cannot process MRP-related activities, leading to the mentioned error.

Steps to Resolve the Error Configuring MRP Controller For Plant in SAP

1. Access the Configuration for MRP Controllers

  • Navigate to the configuration path: SPRO > Production > Material Requirements Planning > Master Data > Define MRP Controller
  • Alternatively, use transaction code OPPR.

2. Define MRP Controllers

  • In the configuration screen, define the MRP controller codes for the relevant plants.
  • Example: If MRP Controller 001 needs to be assigned to Plant THYD, ensure the entry exists.

4. Validate MRP Controller in Material Master

  • Use transaction code MM02 to access the material master data.
  • Navigate to the MRP1 Tab and ensure that the correct MRP Controller (e.g., 001) is assigned to the material.

Additional Tips

  • Check Authorization: Ensure that you have the necessary authorization to configure MRP controllers and maintain material master data.
  • Testing: After completing the configuration, test the setup by attempting to run MRP for the plant and material to confirm the error is resolved.

Conclusion

By following these steps, you can resolve the error “MRP Controller 001 does not exist for plant THYD” and ensure proper MRP functionality for the specified plant. Correct configuration of MRP controllers is critical for smooth material planning and procurement processes in SAP.
