• What is the cause and solution for SAP error message QP081 - Referenced characteristic & is not variable (quantitative) ?

  The SAP error message QP081 indicates that a referenced characteristic in a quality planning context is not defined as a variable characteristic, specifically a quantitative one. This error typically arises when you are trying to create or modify a quality inspection plan or characteristic that requires a quantitative variable characteristic, but the characteristic in question is not set up correctly in the system.
  Cause:
  
  Characteristic Definition: The characteristic you are trying to use is defined as a qualitative characteristic (e.g., a fixed value or a text description) rather than a quantitative one (e.g., a numerical value).
  Master Data Configuration: The characteristic may not be configured properly in the master data settings, leading to it being recognized as non-variable.
  Incorrect Assignment: The characteristic may have been incorrectly assigned to a quality inspection plan or a task list that requires a quantitative variable characteristic.
  
  Solution:
  
  
  Check Characteristic Configuration:
  
  Go to the characteristic definition in the SAP system (transaction code CT04).
  Verify that the characteristic is defined as a variable characteristic and that it is set to be quantitative.
  If it is not set correctly, you may need to change its type to a quantitative variable characteristic.
  
  
  
  Adjust Quality Inspection Plan:
  
  If you are working with a quality inspection plan, ensure that the characteristics included in the plan are all defined as variable and quantitative.
  You can check this in the quality inspection plan (transaction code QP01 or QP02).
  
  
  
  Review Master Data:
  
  Ensure that the master data for the material or product you are working with is correctly set up and that the characteristics are properly assigned.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for more detailed guidance on setting up characteristics and quality inspection plans.
  
  
  
  Seek Help from SAP Support:
  
  If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting SAP Notes for any known issues related to this error.
  
  
  
  Related Information:
  
  Variable Characteristics: These are characteristics that can take on a range of values and are typically used for measurements (e.g., length, weight, temperature).
  Qualitative Characteristics: These are characteristics that describe attributes that cannot be measured numerically (e.g., color, type).
  Quality Management (QM) Module: This error is related to the QM module in SAP, which deals with quality planning, inspection, and control.
  
  By ensuring that the characteristics are correctly defined and configured, you should be able to resolve the QP081 error and proceed with your quality planning tasks.
