  Cause:
  This error usually arises when you are trying to assign a default value to a characteristic that already has a default value assigned. In SAP, each characteristic can have only one default value, and attempting to set another default value for the same characteristic will trigger this error.
  Solution:
  To resolve this error, you can follow these steps:

  Remove or Change Existing Default Value:
  
  If a default value already exists and you want to change it, you will need to remove the existing default value first. This can be done by editing the characteristic and clearing the default value field.
  After removing the existing default value, you can then assign the new default value.
  
  
  
  Review Configuration Settings:
  
  Ensure that your configuration settings are correct and that you are not inadvertently trying to set multiple default values for the same characteristic.
  
  
  
  Check for Dependencies:
  
  If the characteristic is part of a configuration model, check if there are dependencies or constraints that might be affecting the assignment of default values.
  
  
  
  Consult Documentation:
  
  If you are unsure about the implications of changing default values, consult the SAP documentation or your organization's SAP support team for guidance.
