  Cause:
  
  Missing System Name: The error indicates that the system name is not specified in the configuration for the data source or the extraction process. This can happen if the data source is not properly defined or if there are issues with the transport of the data source configuration.
  Incorrect Configuration: The data source might be incorrectly configured, leading to the system not being able to identify the source system from which it needs to extract data.
  Transport Issues: If the data source was transported from one system to another, the system name might not have been correctly updated in the target system.
  Authorization Issues: Sometimes, authorization issues can prevent the system from accessing the necessary configuration data.
  
  Solution:
  
  
  Check Data Source Configuration:
  
  Go to the Data Warehousing Workbench (transaction RSA1).
  Navigate to the relevant data source and check its configuration.
  Ensure that the source system is correctly defined and that the system name is specified.

  Transport Configuration:
  
  If the data source was transported, check the transport logs to ensure that the transport was successful and that all necessary objects were included.
  If necessary, re-transport the data source configuration.
  
  
  
  Check Authorizations:
