This typically occurs when you attempt to delete or change a project or network that is still referenced in other transactions or objects within the system.

  Existing References: The field key you are trying to delete or modify is still being referenced in one or more networks or project structures.

  Solution:
  To resolve the CJ830 error, you can follow these steps:
  
  
  Identify References:
  
  Use transaction codes like CJ20N (Project Builder) or CJ03 (Display Project) to check where the field key is being used.
