• What is the cause and solution for SAP error message RSBK258 - DataSource &2 is currently assigned to real-time daemon &1 ?

  The SAP error message RSBK258 indicates that a specific DataSource (identified by &2) is currently assigned to a real-time daemon (identified by &1). This typically occurs in the context of SAP BW (Business Warehouse) when you are trying to perform an operation that requires the DataSource to be unassigned from the real-time daemon.
  
  Cause:
  The error arises when you attempt to modify, delete, or perform certain operations on a DataSource that is actively being used by a real-time data acquisition process. The real-time daemon is responsible for handling real-time data flows into the SAP BW system, and if a DataSource is still linked to it, the system prevents changes to ensure data integrity and consistency.
  
  Solution:
  To resolve this error, you need to unassign the DataSource from the real-time daemon. Here are the steps to do this:
  
  
  Access the DataSource in SAP BW:
  
  Go to the SAP BW system and navigate to the DataSource in question.
