  Meaning / Cause

  The message indicates that the material you are trying to change, delete, or perform some operation on is currently used or referenced in a CDT.

  Common Scenarios When This Occurs

  Transporting or modifying materials that are linked to customer-specific settings.
  
  
  Solution / How to Resolve
  
  
  Identify the CDT and Usage:
  
  Check which CDT or custom table the material is used in.
  Use transaction codes like SE16 / SE16N or SE11 to look up the custom table.
  Search for the material number in the relevant CDT.
  
  
  
  Evaluate Impact:
  
  Understand the business impact of changing or deleting the material.
  Consult with functional consultants or business users who manage the custom tables.
  
  
  
  Remove or Update References:
  
  If you need to delete the material, first remove or update the entries in the CDT that reference this material.
  If the material is to be blocked or changed, ensure the CDT entries are adjusted accordingly.
  
  
  
  Customizing or Development Support:
  
  If the CDT is part of a custom development, involve your ABAP or development team to understand the dependencies.
