• What is the cause and solution for SAP error message FDT_EXPRESSIONS666 - Mapping for non-existing target step is invalid ?

  The SAP error message FDT_EXPRESSIONS666 typically indicates that there is an issue with a mapping in the context of SAP's Data Transformation (FDT) framework. This error specifically points to a mapping that references a target step that does not exist or is not properly defined in the transformation process.
  Cause:
  
  Missing Target Step: The target step that the mapping is trying to reference has been deleted or is not defined in the transformation.
  Incorrect Mapping Configuration: The mapping configuration may have been set up incorrectly, leading to references to non-existent steps.
  Changes in the Transformation: If the transformation was modified (e.g., steps were added, removed, or renamed), it could lead to inconsistencies in the mapping.
  Transport Issues: If the transformation was transported from one system to another, there might be discrepancies in the target steps due to missing objects.
  
  Solution:
  
  
  Check the Mapping Configuration:
  
  Open the transformation in the FDT editor and verify that all target steps referenced in the mapping exist.
  Ensure that the mappings are correctly configured and that there are no broken references.
  
  
  
  Recreate Missing Steps:
  
  If a target step is missing, you may need to recreate it or adjust the mapping to point to an existing step.
  
  
  
  Validate the Transformation:
  
  Use the validation tools available in the FDT framework to check for any inconsistencies or errors in the transformation.
  
  
  
  Review Recent Changes:
  
  If the transformation was recently modified, review the changes to identify any steps that may have been inadvertently removed or renamed.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, ensure that all necessary objects were included in the transport request and that they were successfully imported into the target system.
  
  
  
  Consult Documentation:
