• What is the cause and solution for SAP error message QP146 - Op. &1, CH &2: Char. ident. &3 used for QDI several times in task list ?

  The SAP error message QP146 indicates that a characteristic (identified by &3) is being used multiple times in a Quality Inspection (QI) task list for a specific operation (identified by &1) and characteristic group (identified by &2). This situation typically arises in the context of Quality Management (QM) in SAP, particularly when dealing with Quality Inspection Plans (QIP) and task lists.
  Cause:
  The error occurs because the same characteristic is defined more than once for the same operation in the task list. This can happen due to:
  
  Duplicate Entries: The characteristic has been inadvertently added multiple times to the same operation in the inspection plan.
  Incorrect Configuration: The configuration of the inspection plan may not be set up correctly, leading to the same characteristic being referenced multiple times.
  Data Migration Issues: If data has been migrated from another system or if there have been changes in the inspection plan, it may lead to duplicates.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Review the Inspection Plan:
  
  Go to the transaction code QP01 (Create Inspection Plan) or QP02 (Change Inspection Plan).
  Locate the inspection plan associated with the operation and characteristic group mentioned in the error message.
  Check the characteristics assigned to the operation and ensure that each characteristic is unique.
  
  
  
  Remove Duplicates:
  
  If you find that the same characteristic is listed multiple times, remove the duplicates so that each characteristic is only assigned once to the operation.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save the inspection plan.
  
  
  
  Test the Changes:
  
  After correcting the inspection plan, try to execute the process that triggered the error again to ensure that the issue has been resolved.
  
  
  
  Related Information:

  Quality Management Configuration: Ensure that your Quality Management module is configured correctly to avoid similar issues in the future.
  User Roles and Authorizations: Ensure that users have the appropriate roles and authorizations to modify inspection plans and task lists.
