• What is the cause and solution for SAP error message RSTRAN515 - No source fields assigned to rule (target: &2 group &3) ?

  The SAP error message RSTRAN515 indicates that there are no source fields assigned to a transformation rule in the context of data transfer between InfoProviders, typically in the context of SAP BW (Business Warehouse) or SAP BW/4HANA. This error usually occurs during the data loading process when the system cannot find any source fields that correspond to the target fields defined in the transformation.
  Cause:
  
  Missing Source Fields: The transformation rule is defined without any source fields mapped to the target fields.
  Incorrect Transformation Configuration: The transformation might not be properly configured, leading to a lack of source field assignments.
  Changes in Data Model: If there have been changes in the source or target data models (like InfoObjects or InfoProviders), it may lead to the loss of field mappings.
  Data Source Issues: The data source might not be active or properly set up, leading to the absence of source fields.
  
  Solution:
  
  
  Check Transformation Settings:
  
  Go to the transformation in the SAP BW system.
  Verify that the source fields are correctly assigned to the target fields. If not, you need to map the appropriate source fields to the target fields.
  
  
  
  Reassign Source Fields:
  
  If the source fields are missing, you may need to reassign them. Open the transformation and add the necessary source fields to the mapping.
  
  
  
  Validate Data Source:
  
  Ensure that the data source is active and correctly configured. Check if the data source is connected to the correct InfoProvider.
  
  
  
  Check for Changes:
  
  If there have been recent changes to the data model, review those changes to ensure that they have not affected the transformation rules.
  
  
  
  Test the Transformation:
  
  After making the necessary adjustments, test the transformation to ensure that it works correctly without errors.
  
  
  
  Transport Requests:
  
  If you are working in a development environment, ensure that any changes made are included in the transport requests to move them to the production environment.
