  Incomplete Deletion: The existing DataSource may not have been completely deleted, or there may be remnants of it in the system.

  To resolve this error, you need to delete the existing DataSource before attempting to create a new one. Here are the steps to do this:
  
  
  Access the DataSource:

  In the Data Warehousing Workbench, go to the "DataSources" section.
  
  
  
  Locate the Existing DataSource:

  Ensure that you are looking in the correct area (e.g., InfoSource, DataSource under a specific source system).
  
  
  
  Delete the DataSource:
  
  Once you find the DataSource, select it and choose the option to delete it.
  Confirm the deletion when prompted.
