• What is the cause and solution for SAP error message RSDHA877 - Target field '&1' has no corresponding field in data source ?

  The SAP error message RSDHA877 indicates that there is a mismatch between the target field in a data target (like an InfoObject or InfoCube) and the fields available in the data source (like an InfoSource or DataSource). This typically occurs during data loading processes in SAP BW (Business Warehouse) when the system tries to map fields from the source to the target and cannot find a corresponding field.
  Cause:
  
  
  Field Mismatch: The target field specified in the error message does not exist in the data source. This could be due to:
  
  The field being removed or renamed in the data source.
  The data source not being updated to include the new field.
  Incorrect configuration in the data flow or transformation.
  
  
  
  DataSource Changes: If the DataSource has been modified (e.g., fields added or removed) after the transformation was created, the mapping may no longer be valid.
  
  
  Transformation Issues: The transformation rules may not be correctly defined, leading to a situation where the system cannot find the necessary fields.
  
  
  Solution:
  
  
  Check DataSource: Verify that the DataSource contains the field mentioned in the error message. You can do this by:
  
  Navigating to the DataSource in the SAP BW system and checking its structure.
  Ensuring that the field is active and available for extraction.
  
  
  
  Update Transformation: If the DataSource has changed, you may need to update the transformation rules:
  
  Go to the transformation that is causing the error.
  Check the mapping between the source fields and the target fields.
  Ensure that all target fields have corresponding source fields.
  
  
  
  Re-activate Objects: If changes were made to the DataSource or transformation, you may need to re-activate the relevant objects:
  
  Re-activate the DataSource.
  Re-activate the transformation.
  Re-activate the InfoPackage if necessary.
  
  
  
  Check for DataSource Enhancements: If the DataSource has been enhanced, ensure that the enhancements are reflected in the transformation.
  
  
  Test Data Load: After making the necessary adjustments, perform a test data load to ensure that the issue is resolved.
  
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like RSA1 (Data Warehousing Workbench) to navigate to the relevant objects and check their configurations.
  Documentation: Refer to SAP documentation for detailed information on DataSources, transformations, and data loading processes.
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific error message or the components you are working with.
  
  By following these steps, you should be able to identify and resolve the issue causing the RSDHA877 error message in your SAP BW environment.
