• What is the cause and solution for SAP error message PPH_MRP404 - Non-regenerative with planning mode: &1 ?

  The SAP error message PPH_MRP404 typically indicates an issue related to the planning mode in the Material Requirements Planning (MRP) process. This error occurs when the system is unable to perform a non-regenerative planning run due to certain conditions not being met.
  Cause:
  
  Planning Mode Configuration: The planning mode specified in the MRP run may not be compatible with the current settings or data in the system.
  Master Data Issues: There may be inconsistencies or missing data in the material master records, such as MRP type, lot size, or planning parameters.
  MRP Area Settings: If MRP areas are configured incorrectly or if there are restrictions on the MRP area, it can lead to this error.
  Locking Issues: If the material is locked for planning or if there are other processes running that prevent the MRP run from executing properly.
  Planning File Entries: The planning file may not have the necessary entries for the materials being processed.
  
  Solution:
  
  Check Planning Mode: Verify the planning mode being used in the MRP run. Ensure that it is set correctly and is appropriate for the materials being planned.
  Review Material Master Data: Check the material master records for the affected materials. Ensure that all necessary fields are filled out correctly, especially those related to MRP (e.g., MRP type, lot size, and planning parameters).
  Examine MRP Area Settings: If MRP areas are used, review their configuration to ensure they are set up correctly and that there are no restrictions that would prevent planning.
  Check for Locks: Investigate if there are any locks on the materials or if other processes are interfering with the MRP run. You can use transaction codes like SM12 to check for locks.
  Planning File Entries: Use transaction code MD21 to check the planning file entries for the materials. If necessary, you can regenerate the planning file entries.
  Run Regenerative Planning: If non-regenerative planning is not working, consider running a regenerative planning run (if appropriate) to see if that resolves the issue.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MD01 (MRP run), MD02 (MRP for single item), and MD21 (Display planning file).
  MRP Types: Understand the different MRP types (e.g., PD, VB, etc.) and their implications on planning.
  SAP Notes: Check for any SAP Notes related to this error message for additional guidance or patches that may address the issue.
  Documentation: Review SAP documentation on MRP processes and planning modes for a deeper understanding of how they function.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or refer to SAP's official support channels for further assistance.
