• What is the cause and solution for SAP error message RSAR220 - Communication structure & does not contain any fields ?

  The SAP error message RSAR220 indicates that the communication structure for a specific DataSource does not contain any fields. This typically occurs in the context of SAP BW (Business Warehouse) when trying to extract data from a source system, and it can be caused by several factors.
  Causes:
  
  DataSource Configuration: The DataSource may not be properly configured. If the DataSource is set up but does not have any fields defined, this error will occur.
  Field Mapping Issues: There may be issues with the field mapping between the source system and the DataSource in BW.
  Technical Settings: The technical settings of the DataSource might not be correctly defined, leading to the absence of fields.
  Source System Issues: The source system might not be providing any data or fields due to issues such as missing authorizations or incorrect data extraction settings.
  Transport Issues: If the DataSource was transported from another system, it might not have been transported correctly, leading to missing fields.
  
  Solutions:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system (transaction code RSA1).
  Verify that the DataSource is correctly configured and that fields are defined in the DataSource.
  
  
  
  Recheck Field Mapping:
  
  Ensure that the field mapping between the source system and the DataSource is correct.
  If necessary, adjust the mapping to include the required fields.
  
  
  
  Review Technical Settings:
  
  Check the technical settings of the DataSource to ensure that the fields are correctly defined.
  You can do this by navigating to the DataSource and checking the "Field" tab.
  
  
  
  Test Data Extraction:
  
  Perform a test extraction to see if data can be pulled from the source system.
  Use transaction code RSA3 to test the DataSource and see if it returns any data.
  
  
  
  Check Source System:
  
  Ensure that the source system is functioning correctly and that there are no issues with data availability.
  Verify that you have the necessary authorizations to access the data in the source system.
  
  
  
  Recreate DataSource:
  
  If the DataSource is still not working, consider deleting and recreating it to ensure that all settings are correctly applied.
