  Cause:
  The error arises when you attempt to assign a characteristic value that has already been assigned to another characteristic or object. This can happen in various scenarios, such as:
  
  Trying to create or modify a characteristic value that already exists in the system.
  Attempting to assign a value to a characteristic that is already linked to another object (e.g., a material or a class).

  Solution:
  To resolve the NGC_API_BASE025 error, you can follow these steps:
  
  
  Check Existing Values:

  If the value must remain assigned to its current characteristic, create a new, unique value for the characteristic you are working with.
  
  
  
  Data Consistency Check:
  
  Ensure that there are no data integrity issues in your system. Sometimes, inconsistencies can arise from data migrations or imports.
