• What is the cause and solution for SAP error message RSDS084 - No primary segment defined ?

  The SAP error message RSDS084: No primary segment defined typically occurs in the context of SAP BW (Business Warehouse) when working with DataSources, especially when trying to load data into InfoProviders or when setting up DataSources for extraction.
  Cause:
  The error indicates that the DataSource you are trying to use does not have a primary segment defined. In SAP BW, a primary segment is essential for the DataSource to function correctly, as it defines the structure of the data being extracted. This can happen due to several reasons:
  
  Missing Configuration: The DataSource may not have been properly configured to include a primary segment.
  Incorrect DataSource Type: The DataSource type may not support primary segments, or it may be incorrectly set up.
  Transport Issues: If the DataSource was transported from another system, it may not have been fully configured in the target system.
  Changes in DataSource: If the DataSource was modified or deleted, it may lead to this error.
  
  Solution:
  To resolve the RSDS084 error, you can follow these steps:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system (transaction code RSA1).
  Ensure that the DataSource has a primary segment defined. You can do this by checking the DataSource's structure in the DataSource maintenance screen.
  
  
  
  Define Primary Segment:
  
  If the primary segment is missing, you will need to define it. This can typically be done in the DataSource maintenance screen by adding the necessary fields to the primary segment.
  
  
  
  Recreate DataSource:
  
  If the DataSource is corrupted or improperly configured, consider deleting and recreating it. Make sure to follow the correct steps to define the primary segment during the creation process.
  
  
  
  Check Transport Requests:
  
  If the DataSource was transported, check the transport logs for any errors. Ensure that all necessary objects were included in the transport request.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on configuring DataSources and primary segments.
  
  
  
  Testing:
  
  After making the necessary changes, test the DataSource to ensure that it is functioning correctly and that the error no longer appears.
