• What is the cause and solution for SAP error message QC026 - Class characteristic &1 has more than two intervals ?

  The SAP error message QC026 indicates that a class characteristic has been defined with more than two intervals, which is not allowed in the context of certain quality management processes. This typically occurs when you are trying to set up a characteristic in a quality inspection plan or a similar configuration where the system expects a binary (yes/no) or a limited range of values.
  Cause:
  The error arises when:
  
  A class characteristic is defined with more than two intervals in the classification system.
  The characteristic is being used in a context that only supports binary or limited interval characteristics (e.g., pass/fail criteria).
  
  Solution:
  To resolve the QC026 error, you can take the following steps:
  
  
  Review Characteristic Definition:
  
  Go to the classification system and check the definition of the characteristic that is causing the error (indicated by &1 in the error message).
  Ensure that the characteristic is defined with the correct number of intervals. If it has more than two, you may need to modify it.
  
  
  
  Modify Intervals:
  
  If the characteristic is indeed defined with more than two intervals, you can either:
  
  Reduce the number of intervals to two or fewer, if applicable.
  Change the characteristic type to one that supports more intervals if your business process allows for it.
  
  
  
  
  
  Check Inspection Plan:
  
  If the characteristic is part of an inspection plan, ensure that the inspection plan is correctly configured to use the characteristic as intended.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources related to quality management and characteristics to ensure compliance with system requirements.
  
  
  
  Testing:
