This error typically occurs in the context of SAP BW (Business Warehouse) when trying to replicate DataSources from an SAP source system or another BW system.
  Causes of RSAR018
  
  
  Connection Issues: There may be a problem with the connection between the source system and the target system. This could be due to network issues, incorrect configuration, or authorization problems.
  
  
  DataSource Not Active: The DataSource you are trying to replicate may not be active in the source system. If the DataSource is not active, it cannot be replicated.
  
  
  Incorrect Configuration: The configuration settings for the DataSource or the source system in the target BW system may be incorrect.
  
  
  Transport Issues: If the DataSource was recently transported from another system, there may be issues with the transport itself.
  
  
  Authorization Issues: The user performing the replication may not have the necessary authorizations to access the DataSource in the source system.
  
  
  Solutions to RSAR018
  
  
  Check Connection: Verify the connection settings between the source and target systems. Ensure that the RFC connection is correctly configured and that the systems can communicate.
  
  
  Activate DataSource: Go to the source system and check if the DataSource is active. If it is not, activate it using transaction code RSA1 (Data Warehousing Workbench) and navigate to the DataSource.
  
  
  Review Configuration: Check the configuration of the DataSource in the target system. Ensure that all settings are correct and that the DataSource is properly defined.
  
  
  Check Authorizations: Ensure that the user performing the replication has the necessary authorizations in both the source and target systems. This includes access to the DataSource and the ability to perform replication tasks.
  
  
  Check for Transport Issues: If the DataSource was recently transported, check the transport logs for any errors. You may need to re-transport the DataSource or correct any issues identified in the transport.
  
  
  Review Logs: Check the BW system logs for more detailed error messages that may provide additional context for the issue. You can use transaction SLG1 to view application logs.
