• What is the cause and solution for SAP error message RSM1305 - DataSource &1 in the source system is still assigned to an InfoSource. ?

  The SAP error message RSM1305 indicates that a DataSource is still assigned to an InfoSource in the source system, which is preventing certain operations, such as deletion or modification of the DataSource. This typically occurs in the context of SAP BW (Business Warehouse) when you are trying to manage DataSources.
  Cause:
  The error occurs because the DataSource you are trying to modify or delete is still linked to an InfoSource. An InfoSource is a structure in SAP BW that defines how data is extracted from a source system. If a DataSource is assigned to an InfoSource, it cannot be removed or altered until that assignment is cleared.
  Solution:
  To resolve this error, you need to follow these steps:
  
  
  Identify the InfoSource: Determine which InfoSource the DataSource is currently assigned to. You can do this by checking the InfoSource settings in the SAP BW system.
  
  
  Remove the Assignment:
  
  Go to the InfoSource in the SAP BW system.
  Navigate to the DataSource assignments.
  Remove the assignment of the DataSource from the InfoSource.
  
  
  
  Check for Other Dependencies: Ensure that there are no other objects (like InfoPackages, Data Transfer Processes, etc.) that are dependent on the DataSource. If there are, you may need to adjust or delete those dependencies as well.
  
  
  Re-attempt the Operation: Once the DataSource is no longer assigned to the InfoSource, you should be able to perform the desired operation (e.g., delete or modify the DataSource) without encountering the error.
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like RSA1 (Data Warehousing Workbench) to manage DataSources and InfoSources.
  Documentation: Refer to SAP Help documentation for detailed information on managing DataSources and InfoSources in BW.
  Transport Requests: If you are working in a development environment, ensure that any changes you make are included in a transport request if they need to be moved to production.
  
  By following these steps, you should be able to resolve the RSM1305 error and manage your DataSources effectively.
