• What is the cause and solution for SAP error message RSAR387 - Assignment of InfoObjects to DataSource & fields incomplete ?

  The SAP error message RSAR387 indicates that there is an issue with the assignment of InfoObjects to a DataSource in the context of SAP BW (Business Warehouse). This error typically arises when the DataSource is not properly configured, and it can prevent data extraction from the source system.
  Cause:
  The error can occur due to several reasons:
  
  Incomplete Assignment: The InfoObjects (characteristics or key figures) are not fully assigned to the DataSource. This means that some fields in the DataSource do not have corresponding InfoObjects defined.
  Missing InfoObjects: The InfoObjects that are supposed to be linked to the DataSource may not exist or may not be activated.
  DataSource Configuration Issues: The DataSource itself may not be configured correctly, leading to incomplete mappings.
  Transport Issues: If the DataSource was transported from another system, there may be inconsistencies in the InfoObject assignments.
  
  Solution:
  To resolve the RSAR387 error, follow these steps:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system (transaction code RSA1).
  Navigate to the DataSource and check the "Field Mapping" or "DataSource Structure" to ensure that all fields are correctly assigned to the corresponding InfoObjects.
  
  
  
  Assign Missing InfoObjects:
  
  If you find that some fields are not assigned to any InfoObject, you need to assign the appropriate InfoObjects to those fields.
  You can do this by editing the DataSource and adding the necessary InfoObjects.
  
  
  
  Activate InfoObjects:
  
  Ensure that all InfoObjects that are supposed to be linked to the DataSource are activated. You can check this in the InfoObject maintenance (transaction code RSD1).
  
  
  
  Check for Transport Issues:
  
  If the DataSource was recently transported, ensure that all related objects (like InfoObjects) were also transported correctly and are in sync.
  
  
  
  Recheck DataSource:
  
  After making the necessary changes, recheck the DataSource to ensure that the error is resolved. You can do this by trying to execute the data extraction again.
  
  
  
  Consult Documentation:
  
  If the issue persists, consult SAP documentation or support for further troubleshooting steps specific to your version of SAP BW.
