This error typically arises in the context of materials management or production planning when the system is unable to find the necessary configuration for unitization, which is the process of defining how materials are packaged or handled in units.
  Cause:
  
  Missing Configuration: The most common cause of this error is that the unitization parameters have not been set up in the system. This could include missing definitions for packaging materials, handling units, or other related settings.
  Incorrect Master Data: The material master data may not have the necessary unitization information defined, leading to this error when trying to process transactions involving that material.
