• What is the cause and solution for SAP error message PPH_MRP163 - Material is to be planned by external system ?

  The SAP error message PPH_MRP163 indicates that a material is set to be planned by an external system rather than by the SAP system itself. This typically occurs in environments where materials are managed through an external planning system, such as a third-party supply chain management tool or an advanced planning system (APS).
  Cause:
  
  External Planning Configuration: The material is configured in the system to be planned externally. This is often set in the material master data or in the planning settings.
  MRP Type: The MRP type for the material may be set to a type that indicates external planning (e.g., "X" for external planning).
  Master Data Settings: The material master record may have specific settings that direct the planning to an external system.
  Integration Issues: There may be issues with the integration between SAP and the external planning system, leading to the system not recognizing the material for internal planning.
  
  Solution:
  
  
  Check Material Master Data: 
  
  Go to the material master (transaction code MM03) and check the MRP views. Look for the MRP type and planning settings.
  If the material should be planned internally, change the MRP type to an appropriate value (e.g., "PD" for MRP) and save the changes.
  
  
  
  Review Planning Parameters: 
  
  Ensure that the planning parameters are correctly set up in the configuration for the material. This includes checking the MRP type, lot size, and other relevant settings.
  
  
  
  Consult with External System: 
  
  If the material is indeed meant to be planned externally, ensure that the external system is correctly configured and that there are no issues with data transfer or integration.
  
  
  
  Check for Customizations: 
  
  If there are custom developments or enhancements in your SAP system, check if any of these are affecting the planning behavior of the material.
  
  
  
  Documentation and Support: 
  
  Refer to SAP documentation or consult with your SAP support team for specific guidance related to your system configuration and integration with external systems.
  
  
  
  Related Information:
  
  MRP Types: Understanding the different MRP types and their implications on planning can help in configuring materials correctly.
  Integration with External Systems: Familiarize yourself with how your SAP system integrates with external planning systems, including any middleware or interfaces that may be in use.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide additional guidance on handling this error message.
  
  By following these steps, you should be able to resolve the PPH_MRP163 error and ensure that the material is planned according to your business requirements.
