• What is the cause and solution for SAP error message RSAR252 - Communication structure for InfoSource & not maintained ?

  The SAP error message RSAR252 indicates that the communication structure for a specific InfoSource is not maintained. This typically occurs in the context of SAP BW (Business Warehouse) when trying to extract data from a source system, and it suggests that the necessary configuration for the InfoSource is incomplete or missing.
  Cause:
  
  Missing Communication Structure: The communication structure for the specified InfoSource has not been defined or activated in the system.
  Incorrect InfoSource Configuration: The InfoSource may not be properly configured to link to the data source.
  Transport Issues: If the InfoSource was recently transported from another system, the communication structure may not have been included in the transport.
  DataSource Issues: The underlying DataSource may not be correctly set up or may not be compatible with the InfoSource.
  
  Solution:
  To resolve the RSAR252 error, follow these steps:
  
  
  Check InfoSource Configuration:
  
  Go to the SAP BW transaction RSA1 (Data Warehousing Workbench).
  Navigate to the InfoSources section and locate the InfoSource that is causing the error.
  Ensure that the communication structure is defined and activated.
  
  
  
  Create or Maintain Communication Structure:
  
  If the communication structure is missing, you may need to create it. This can be done by:
  
  Going to the transaction RSA2 (DataSource Maintenance).
  Selecting the relevant DataSource and checking if the communication structure is defined.
  If not, you can create it by using the Communication Structure option.
  
  
  
  
  
  Activate the Communication Structure:
  
  After creating or modifying the communication structure, ensure that it is activated. You can do this in the same maintenance area.
  
  
  
  Check DataSource:
  
  Ensure that the DataSource linked to the InfoSource is correctly configured and active. You can check this in the DataSource maintenance transaction (RSA1 or RSA2).
  
  
  
  Transport Issues:
  
  If the InfoSource was transported, ensure that all related objects, including the communication structure, were included in the transport request.
  
  
  
  Testing:
  
  After making the necessary changes, test the extraction process again to see if the error persists.
