• What is the cause and solution for SAP error message DB6PM168 - Data class &1 is still in use, deletion not possible ?

  The SAP error message DB6PM168 indicates that a specific data class (denoted as &1 in the message) is still in use, which prevents its deletion. This typically occurs in the context of database management within SAP, particularly when dealing with database tables or data classes that are linked to active objects or processes.
  Cause:
  
  Active References: The data class you are trying to delete is still being referenced by active database objects, such as tables, indexes, or views.
  Open Transactions: There may be open transactions or sessions that are using the data class, preventing its deletion.
  Dependencies: Other database objects may depend on the data class, making it impossible to delete without first addressing those dependencies.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Active References:
  
  Use transaction codes like SE11 (Data Dictionary) or SE14 (Database Utility) to check for any active references to the data class.
  Look for tables, views, or indexes that are associated with the data class.
  
  
  
  Check for Open Transactions:
  
  Ensure that there are no open transactions or sessions that are using the data class. You can use transaction SM12 to check for locks and SM21 for system logs.
  
  
  
  Remove Dependencies:
  
  If there are dependent objects, you will need to either delete or modify them to remove the dependency on the data class.
  This may involve dropping tables or views that are linked to the data class.
  
  
  
  Use Database Utility:
  
  If you are sure that the data class is no longer needed, you can use transaction SE14 to perform a database utility operation to check and delete the data class after ensuring that all dependencies are resolved.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP Basis team for specific guidelines related to your SAP version and database system.
  
  
  
  Backup:
  
  Before making any deletions, ensure that you have a backup of your database or relevant data to prevent accidental data loss.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific guidance or patches related to this error message.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE11, SE14, SM12, and SM21 for managing database objects and monitoring system locks.
  Database Administration: If you are not familiar with database administration tasks, consider involving your SAP Basis team or a database administrator to assist with the process.
  
  By following these steps, you should be able to identify the cause of the error and take appropriate action to resolve it.
