• What is the cause and solution for SAP error message QP102 - There is no unit of measure assigned ?

  The SAP error message QP102 ("There is no unit of measure assigned") typically occurs in the context of Quality Management (QM) when you are trying to perform a quality inspection or related activity, and the system cannot find a unit of measure (UoM) for the material or inspection lot you are working with.
  Cause:
  
  Missing Unit of Measure: The most common cause is that the material master record does not have a unit of measure assigned for the relevant views (e.g., purchasing, sales, or basic data).
  Incorrect Configuration: The unit of measure might not be properly configured in the system, or the relevant settings in the material master might be incomplete.
  Inspection Plan Issues: If you are using an inspection plan, it may not have the correct unit of measure defined.
  Material Type Restrictions: Certain material types may have restrictions or specific configurations that affect how units of measure are assigned.
  
  Solution:
  
  
  Check Material Master:
  
  Go to the material master record (transaction code MM03).
  Check the relevant views (Basic Data, Purchasing, Sales, etc.) to ensure that a unit of measure is assigned.
  If it is missing, you can add the appropriate unit of measure using transaction code MM02 (Change Material).
  
  
  
  Review Inspection Plan:
  
  If you are using an inspection plan, check the plan to ensure that it has the correct unit of measure assigned.
  You can use transaction code QP01 to display or change the inspection plan.
  
  
  
  Check UoM Configuration:
  
  Ensure that the unit of measure is defined in the system. You can check this in the configuration settings (transaction code SPRO).
  Navigate to Logistics - General > Material Master > Basic Settings > Units of Measure to verify the configuration.
  
  
  
  Material Type Settings:
  
  If the material type has specific settings that affect unit of measure assignment, review those settings in the configuration.
  
  
  
  Recreate Inspection Lot:
  
  If the inspection lot was created before the unit of measure was assigned, you may need to recreate the inspection lot after making the necessary changes.
