• What is the cause and solution for SAP error message DB6PM123 - Tablespace &1 is still allocated to data class &2 ?

  The SAP error message DB6PM123 indicates that a specific tablespace is still allocated to a data class, which can prevent certain operations from being performed on that tablespace. This error typically arises in the context of database management within SAP systems, particularly when dealing with database administration tasks.
  Cause:
  The error occurs when you attempt to perform an operation (like dropping or modifying a tablespace) on a tablespace that is still associated with a specific data class. In SAP, data classes are used to categorize data based on its usage and storage requirements. If a tablespace is still allocated to a data class, it cannot be modified or deleted until the association is removed.
  Solution:
  To resolve this error, you need to follow these steps:
  
  
  Identify the Data Class: Determine which data class the tablespace is currently allocated to. This information is provided in the error message itself.
  
  
  Remove the Allocation:
  
  Use the SAP transaction code SE11 (Data Dictionary) or SE14 (Database Utility) to access the relevant data class settings.
  Navigate to the data class configuration and check the tablespace allocation.
  Remove the allocation of the tablespace from the data class. This may involve changing the settings in the database configuration or adjusting the data class assignments.
  
  
  
  Check Dependencies: Ensure that there are no other dependencies or objects that are still using the tablespace. You may need to check for any active database connections or locks.
  
  
  Retry the Operation: Once the allocation has been removed, you can retry the operation that initially triggered the error.
  
  
  Related Information:
