• What is the cause and solution for SAP error message RSDHA079 - No suitable field mappings found ?

  The SAP error message RSDHA079 ("No suitable field mappings found") typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the data source or the transformation process. This error indicates that the system is unable to find appropriate field mappings between the source and target structures during data extraction or transformation.
  Causes:
  
  Missing Field Mappings: The most common cause is that the field mappings between the source and target data structures are not defined or are incomplete.
  Changes in Data Source: If the underlying data source (like an InfoSource or DataSource) has been changed (e.g., fields added or removed), the mappings may no longer be valid.
  Incorrect Transformation: The transformation rules may not be correctly set up, leading to a mismatch between the source and target fields.
  DataSource Activation: The DataSource may not be activated properly, which can lead to issues in field mapping.
  Versioning Issues: If there are multiple versions of the DataSource or InfoObject, the system may be referencing the wrong version.
  
  Solutions:
  
  Check Field Mappings: Go to the transformation in the Data Warehousing Workbench (transaction RSA1) and verify that all necessary field mappings are defined correctly.
  Recreate Transformation: If the mappings are missing or incorrect, consider recreating the transformation to ensure that all fields are correctly mapped.
  Activate DataSource: Ensure that the DataSource is activated. You can do this in the DataSource maintenance transaction (transaction RSA5).
  Check for Changes: Review any recent changes made to the DataSource or InfoObjects that might have affected the mappings. If changes were made, update the transformation accordingly.
  Test Data Transfer: Use the Data Transfer Process (DTP) to test the data transfer and see if the error persists. This can help identify if the issue is with the transformation or the data source.
  Check for Version Conflicts: Ensure that you are using the correct version of the DataSource and that there are no conflicts with other versions.
