• What is the cause and solution for SAP error message 61839 - No firming type for reorder point or time-phased material planning ?

  The SAP error message 61839, "No firming type for reorder point or time-phased material planning," typically occurs in the context of material requirements planning (MRP) when the system is unable to determine a firming type for a material that is set up for reorder point planning or time-phased planning.
  Cause:
  
  Missing Firming Type: The material master record does not have a firming type defined for the relevant planning strategy.
  Incorrect Planning Strategy: The planning strategy assigned to the material may not be compatible with the firming process.
  Configuration Issues: There may be configuration issues in the MRP settings that prevent the system from determining a firming type.
  Material Master Data: The material master data may be incomplete or incorrectly maintained, particularly in the MRP views.
  
  Solution:
  
  
  Check Material Master:
  
  Go to the material master record (transaction code MM03) and check the MRP views.
  Ensure that the firming type is correctly defined in the MRP 2 view.
  
  
  
  Review Planning Strategy:
  
  Verify that the planning strategy assigned to the material is appropriate for the type of planning you are performing.
  If necessary, change the planning strategy to one that supports firming.
  
  
  
  Configure MRP Settings:
  
  Check the configuration settings for MRP in the SPRO transaction (Customizing).
  Ensure that the firming types are correctly defined in the MRP configuration.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to MRP and firming types to understand the requirements and settings.
  
  
  
  Test with Different Materials:
  
  If possible, test the firming process with other materials that are known to work correctly to isolate the issue.
  
  
  
  Consult with SAP Support:
  
  If the issue persists, consider reaching out to SAP support for further assistance, especially if it appears to be a system bug or a deeper configuration issue.
  
  
  
  Related Information:

  MRP Views: The MRP views in the material master contain critical information for how the material is planned, including reorder points, safety stock, and lead times.
