• What is the cause and solution for SAP error message RM328 - Inspection lot cannot be created as max. lot size = 0 ?

  The SAP error message RM328 indicates that an inspection lot cannot be created because the maximum lot size is set to zero. This typically occurs in the context of quality management (QM) when trying to create an inspection lot for a material or process that has not been properly configured.
  Cause:
  
  Maximum Lot Size Configuration: The maximum lot size for the inspection lot is set to zero in the material master or in the quality management settings. This means that the system does not allow the creation of any inspection lots for that material.
  Quality Management Settings: The quality management settings for the material or the inspection plan may not be correctly defined, leading to this error.
  Material Master Data: The material master data may not have been fully maintained, particularly in the QM view.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master (transaction code MM02 or MM03).
  Check the QM view and ensure that the maximum lot size is set to a value greater than zero.
  If it is set to zero, update it to an appropriate value based on your business requirements.
  
  
  
  Review Inspection Plan:
  
  Check the inspection plan associated with the material (transaction code QP01 or QP02).
  Ensure that the lot size settings in the inspection plan are correctly defined.
  
  
  
  Quality Management Configuration:
  
  Review the configuration settings in the Quality Management module (transaction code SPRO).
  Navigate to the relevant settings for inspection lot creation and ensure that the maximum lot size is configured correctly.
  
  
  
  Check for Batch Management:
  
  If batch management is enabled for the material, ensure that the batch characteristics and settings are also correctly defined.
  
  
  
  Consult Documentation:
  
  If you are unsure about the correct settings, consult the SAP documentation or your organization's SAP support team for guidance on how to configure the maximum lot size appropriately.
