• What is the cause and solution for SAP error message C7108 - Lot size is not within selected lot size range ?

  The SAP error message C7108, "Lot size is not within selected lot size range," typically occurs in the context of production planning or material requirements planning (MRP) when the lot size specified for a production order or purchase requisition does not fall within the defined lot size range for the material in question.
  Cause:
  
  Lot Size Configuration: The material master record for the item may have a defined lot size range that the specified lot size does not meet. This can happen if the lot size is set too low or too high compared to the minimum and maximum lot sizes defined in the material master.
