• What is the cause and solution for SAP error message PPH_MRP405 - Regenerative with planning mode: &1 ?

  The SAP error message PPH_MRP405 typically occurs during the planning process in the Material Requirements Planning (MRP) module. This error indicates that there is an issue with the regenerative planning mode, which is a specific type of planning run that recalculates all requirements and stock levels for the materials involved.
  Cause:
  The error message PPH_MRP405 can be triggered by several factors, including:
  
  Incorrect Planning Mode: The planning mode specified may not be appropriate for the material or the current planning scenario.
  Data Inconsistencies: There may be inconsistencies in the master data, such as material master records, BOMs (Bill of Materials), or routing information.
  Locking Issues: The material may be locked for planning by another user or process, preventing the regenerative planning from executing.
  Configuration Issues: There may be configuration settings in the MRP area that are not set up correctly, leading to this error.
  Missing Parameters: Required parameters for the planning run may be missing or incorrectly set.
  
  Solution:
  To resolve the PPH_MRP405 error, you can take the following steps:
  
  
  Check Planning Mode: Verify that the planning mode specified is appropriate for the material. You can do this by checking the MRP settings in the material master (transaction MM03).
  
  
  Review Master Data: Ensure that all relevant master data (material master, BOM, routing) is complete and accurate. Look for any missing or incorrect entries.
  
  
  Check for Locks: Use transaction SM12 to check if the material is locked by another user or process. If it is, you may need to wait for the lock to be released or contact the user who has the lock.
  
  
  Configuration Review: Review the MRP configuration settings in the system (transaction SPRO) to ensure that they are set up correctly for the materials you are planning.
  
  
  Run MRP in a Different Mode: If regenerative planning is not necessary, consider running MRP in a different mode (e.g., net change planning) to see if that resolves the issue.
  
  
  Check Logs: Review the MRP logs for additional details on the error. This can provide more context on what specifically is causing the issue.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on the error and potential fixes.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM03 (Display Material), MD01 (MRP Run), and SM12 (Display and Delete Locks).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  MRP Configuration: Understanding MRP configuration settings can help in troubleshooting and preventing similar issues in the future.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP support team or reach out to SAP support for further assistance.
