• What is the cause and solution for SAP error message RSAOLTP018 - Transfer structure for DataSource &1(&2) is inactive ?

  The SAP error message RSAOLTP018 indicates that the transfer structure for a specific DataSource is inactive. This typically occurs in the context of SAP BW (Business Warehouse) when trying to load data from an OLTP (Online Transaction Processing) system into the BW system.
  Cause:
  The error is caused by the transfer structure associated with the specified DataSource being inactive. This can happen for several reasons:
  
  The DataSource has been created but not activated.
  The transfer structure was modified and needs to be reactivated.
  There may be inconsistencies in the DataSource or transfer structure configuration.
  
  Solution:
  To resolve the error, you need to activate the transfer structure for the specified DataSource. Here are the steps to do this:
  
  
  Access the DataSource in SAP BW:
  
  Go to the SAP BW system.
  Navigate to the DataSource in the Data Warehousing Workbench (transaction code RSA1).
  
  
  
  Locate the Transfer Structure:
  
  In the Data Warehousing Workbench, find the DataSource that is causing the error.
  Check the transfer structure associated with the DataSource.
  
  
  
  Activate the Transfer Structure:
  
  Right-click on the transfer structure and select the option to activate it.
  Alternatively, you can use transaction code RSA2 to directly access the DataSource and activate the transfer structure.
  
  
  
  Check for Errors:
  
  After activation, check for any errors or warnings that may need to be addressed.
  Ensure that the DataSource is correctly configured and that all necessary fields are included.
  
  
  
  Test the Data Transfer:
  
  Once the transfer structure is activated, attempt to load data again to verify that the issue is resolved.
