• What is the cause and solution for SAP error message UJA_CHECK_BIZ_RULES017 - The field should not be the same as Source DataSource ?

  The SAP error message UJA_CHECK_BIZ_RULES017 indicates that there is a business rule violation in the context of data extraction or transformation processes, particularly when working with DataSources in SAP BW (Business Warehouse). The specific message "The field should not be the same as Source DataSource" suggests that there is a configuration issue where a field is incorrectly set to be the same as the source DataSource.
  Cause:
  This error typically occurs in the following scenarios:
  
  Field Mapping Issue: During the configuration of a DataSource or InfoPackage, a field in the target structure is incorrectly mapped to the same field in the source DataSource.
  Transformation Rules: In the transformation rules between the source and target, a field may have been defined to take its value from the same field in the source DataSource, which is not allowed.
  Data Modeling Error: There may be a logical error in the data model where the same field is being referenced incorrectly.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource configuration in the SAP BW system.
  Verify the field mappings and ensure that no field in the target structure is mapped to the same field in the source DataSource.
  
  
  
  Review Transformation Rules:
  
  Navigate to the transformation that is causing the issue.
  Check the mapping of fields and ensure that the target fields are not set to pull data from the same source field.
  
  
  
  Adjust Field Mappings:
  
  If you find any fields that are incorrectly mapped, adjust the mappings so that they reference different fields or are set to a valid transformation logic.
  
  
  
  Test the Changes:
  
  After making the necessary adjustments, test the DataSource or InfoPackage to ensure that the error no longer occurs.
  
  
  
  Consult Documentation:
  
  If you are unsure about the correct mappings or transformations, refer to SAP documentation or consult with a BW expert to ensure compliance with best practices.
