  The SAP error message RSDRO105 indicates that there is a problem with the uniqueness of a task name in the context of data extraction or data transfer processes, particularly in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence). The error message typically arises when there are multiple tasks with the same name in the same context, which can lead to confusion in processing.
  Cause:
  
  Duplicate Task Names: The most common cause of this error is that there are multiple tasks defined with the same name in the same InfoPackage or data transfer process (DTP).
  Incorrect Configuration: Sometimes, the configuration of the data extraction process may not have been set up correctly, leading to naming conflicts.

  Solution:
  
  
  Identify Duplicate Tasks: 
  
  Go to the relevant transaction (e.g., RSA1 for Data Warehousing Workbench) and check the InfoPackages or DTPs to identify where the duplicate task names exist.
  You can also use transaction SE11 to check the relevant tables for duplicate entries.
  
  
  
  Rename or Delete Duplicates: 
  
  If you find duplicate task names, you can either rename them to ensure uniqueness or delete the unnecessary duplicates.
  Ensure that the new names follow the naming conventions and are meaningful for future reference.
  
  
  
  Check Transport Requests: 
  
  If the issue arose after a transport, check the transport requests to ensure that they did not inadvertently create duplicates. You may need to adjust the transport or re-import it.
  
  
  
  Consistency Check: 
  
  After making changes, perform a consistency check on the InfoProvider or DTP to ensure that everything is functioning correctly.
  
  
  
  Testing:
