This error indicates that there is an attempt to create or register an object (like a rule, decision table, or other configuration) with a key that already exists in the system.
  Cause:
  
  
  Duplicate Key: The most common cause of this error is that the system is trying to create a new entry with a key that is already in use. This could happen if:
  
  You are trying to import or activate a configuration that has the same key as an existing one.

  System Migration or Transport Issues: If you are migrating data or transporting objects between systems, there may be conflicts with existing keys.
  
  
  Manual Entry Errors: If users are manually entering keys, they may inadvertently create duplicates.
  
  
  Solution:
  
  
  Check Existing Keys: 
  
  Review the existing configurations in the system to identify if the key in question is already in use. You can do this by navigating to the relevant configuration area in the SAP GUI or using transaction codes related to the Business Rules Framework.
  
  
  
  Modify or Delete Existing Entry: 
  
  If you find that the key is indeed in use and you need to create a new entry, consider modifying the existing entry or deleting it if it is no longer needed.
  
  
  
  Use Unique Identifiers: 
  
  When creating new configurations, ensure that you are using unique identifiers to avoid conflicts.
