  Solution:
  To resolve this error, you need to follow these steps:
  
  
  Check Assignments:
  
  Go to the configuration settings for costing variants (Transaction code: OKTZ).
  Check which costing variants are assigned to the cost component structure you want to delete.
  
  
  
  Remove Assignments:
  
  If the cost component structure is assigned to a costing variant, you will need to remove this assignment first.
  Navigate to the costing variant settings and remove the reference to the cost component structure.

  Check for Other Dependencies:
  
  Ensure that there are no other dependencies or references to the cost component structure in other configurations or master data.
  
  
  
  Transport Requests:
  
  If you are working in a development environment, ensure that any changes are included in transport requests if they need to be moved to production.
  
  
  
  Related Information:
