• What is the cause and solution for SAP error message RSCRT126 - No active communication structure found for InfoSource '&1'. Termination ?

  The SAP error message RSCRT126 indicates that there is no active communication structure found for the specified InfoSource. This error typically occurs in the context of SAP BW (Business Warehouse) when trying to extract data from a source system or when working with InfoSources in the data flow.
  Cause:
  
  Inactive InfoSource: The InfoSource you are trying to use may not be active or properly configured in the system.
  Missing Communication Structure: The communication structure that is supposed to be linked to the InfoSource might be missing or not defined correctly.
  Transport Issues: If the InfoSource was recently transported from another system, it may not have been activated properly in the target system.
  DataSource Issues: The underlying DataSource might not be correctly set up or activated, leading to the InfoSource being unable to find the necessary communication structure.
  
  Solution:
  
  
  Check Activation: 
  
  Go to the InfoSource in the SAP BW system and ensure that it is activated. You can do this by navigating to the InfoSource in the Data Warehousing Workbench (transaction RSA1) and checking its status.
  
  
  
  Verify Communication Structure:
  
  Ensure that the communication structure associated with the InfoSource is defined and active. You can check this in the DataSource settings.
  If the communication structure is missing, you may need to create or regenerate it.
  
  
  
  Re-activate DataSource:
  
  If the DataSource is not active, activate it. You can do this in the DataSource maintenance transaction (transaction RSA1) by selecting the DataSource and choosing the activation option.
  
  
  
  Check Transport Requests:
  
  If the InfoSource was transported, ensure that all related objects (like DataSources and communication structures) were also transported and activated in the target system.
  
  
  
  Review Logs:
  
  Check the system logs for any additional error messages or warnings that might provide more context about the issue.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific InfoSource or DataSource for any known issues or additional configuration steps.
