• What is the cause and solution for SAP error message M3428 - Fixed lot size and minimum lot size not possible in a single profile ?

  The SAP error message M3428 indicates that there is a conflict in the configuration of lot sizes for a material in the system. Specifically, it arises when you attempt to set both a fixed lot size and a minimum lot size in the same lot size profile, which is not allowed.
  
  Cause:
  
  
  Configuration Conflict: The error occurs because the system does not allow a lot size profile to have both a fixed lot size and a minimum lot size defined simultaneously. A fixed lot size means that the system will always produce or order a specific quantity, while a minimum lot size indicates the smallest quantity that can be produced or ordered. These two settings are inherently contradictory.
  
  
  Material Master Settings: The error may also stem from the settings in the material master record, particularly in the MRP (Material Requirements Planning) views where lot size profiles are defined.
