• What is the cause and solution for SAP error message M3452 - Fixed lot size and ordering costs not possible in one profile ?

  The SAP error message M3452, which states "Fixed lot size and ordering costs not possible in one profile," typically occurs in the context of Material Requirements Planning (MRP) when there is a configuration issue with the lot size settings in the material master or the MRP parameters.
  Cause:
  This error arises when you attempt to use both fixed lot size and ordering costs in the same lot size profile. In SAP, fixed lot size means that the system will always produce or order a specific quantity, while ordering costs are associated with the costs incurred each time an order is placed. These two settings are mutually exclusive in the same profile because fixed lot sizes do not allow for variable ordering costs.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Lot Size Profile:
  
  Go to the material master record (transaction code MM03) and check the MRP 2 view.
  Look for the lot size settings and see if both fixed lot size and ordering costs are defined.
  
  
  
  Adjust Lot Size Settings:
  
  If you need to use a fixed lot size, remove the ordering costs from the lot size profile.
  Conversely, if you need to maintain ordering costs, change the lot size to a variable type (e.g., lot-for-lot or other variable lot sizes).
  
  
  
  Review MRP Parameters:
  
  Check the MRP parameters in the configuration (transaction code SPRO) under the relevant MRP settings.
  Ensure that the lot size profile is correctly configured according to your business requirements.
  
  
  
  Test Changes:
  
  After making the necessary adjustments, run the MRP process again to see if the error persists.
