  The SAP error message RSM1303 indicates that the system has successfully deleted an unassigned DataSource from a source system. This message is informational rather than an error, meaning that it is not indicative of a problem but rather a notification that a specific action has been completed.
  Cause:
  The message is triggered when a DataSource that is not assigned to any InfoSource or InfoPackage is deleted from the system. This can happen during routine maintenance or cleanup processes where unassigned DataSources are removed to keep the system organized and efficient.
  Solution:
  Since this message is informational, there is typically no action required unless you are concerned about the deletion of the DataSource. If you need the DataSource for future use, you should ensure that it is assigned to an InfoSource or InfoPackage before it gets deleted. If you want to prevent this message from appearing, you can:
  
  Review DataSources: Regularly check your DataSources to ensure that they are assigned as needed.
  Reassign DataSources: If you find that a DataSource is unassigned but still needed, you can reassign it to the appropriate InfoSource or InfoPackage.
  Documentation: Keep documentation of your DataSources and their assignments to avoid confusion.
