• What is the cause and solution for SAP error message RSAOLTP070 - No link exists for DataSource &1 with source system &2 ?

  The SAP error message RSAOLTP070 indicates that there is no link established for the specified DataSource with the given source system. This typically occurs in the context of SAP BW (Business Warehouse) when trying to extract data from an SAP source system (like an SAP ERP system) into the BW system.
  Cause:
  
  Missing or Incorrect Source System Configuration: The source system may not be properly configured in the BW system. This includes not having the correct RFC connection or not having the DataSource linked to the source system.
  DataSource Not Activated: The DataSource may not be activated in the source system or in the BW system.
  Transport Issues: If the DataSource was transported from one system to another, it may not have been properly linked to the source system.
  Authorization Issues: The user may not have the necessary authorizations to access the DataSource or the source system.
  
  Solution:
  
  
  Check Source System Configuration:
  
  Go to the SAP BW system and check the configuration of the source system in transaction RSA1 (Data Warehousing Workbench).
  Ensure that the source system is correctly defined and that the RFC connection is working.
  
  
  
  Link DataSource to Source System:
  
  In transaction RSA1, navigate to the DataSources section.
  Find the DataSource in question and check if it is linked to the correct source system. If not, you may need to create a link.
  You can do this by right-clicking on the DataSource and selecting the option to create a link to the source system.
  
  
  
  Activate DataSource:
  
  Ensure that the DataSource is activated in both the source system and the BW system. You can activate it in the BW system using transaction RSA1 or RSC1.
  
  
  
  Check Authorizations:
  
  Verify that the user has the necessary authorizations to access the DataSource and the source system. This may involve checking roles and authorizations in both the BW and source systems.
  
  
  
  Transport Issues:
  
  If the DataSource was transported, ensure that all necessary objects were transported correctly and that the DataSource is properly linked in the target system.
