• What is the cause and solution for SAP error message FDT_EXPRESSIONS670 - Mapping-Delta has to refer to added step &1 as source or as target ?

  The SAP error message FDT_EXPRESSIONS670 typically occurs in the context of SAP Data Services or SAP Process Integration (PI) when working with mappings in the context of the SAP Data Transformation (FDT) framework. This error indicates that there is an issue with the mapping configuration, specifically related to the use of a step that has been added to the mapping.
  Cause:
  The error message suggests that the mapping delta (the changes made to the mapping) is not correctly referencing a newly added step. This can happen if:
  
  A new step was added to the mapping, but the existing expressions or mappings do not reference this new step correctly.

  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the Mapping Configuration:
  
  Open the mapping where the error occurred.
  Verify that the newly added step is correctly configured and that it is intended to be used as either a source or a target.
  
  
  
  Update Expressions:
  
  Review any expressions or transformations that reference the new step. Ensure that they are correctly pointing to the new step as either a source or a target.
  If necessary, modify the expressions to include the new step.
  
  
  
  Validate the Mapping:
  
  After making changes, validate the mapping to ensure that there are no other errors or warnings.
  Use the validation tools provided in the SAP Data Services or FDT environment to check for consistency.
  
  
  
  Test the Mapping:
  
  Once the mapping is updated and validated, run a test to ensure that the mapping works as expected without triggering the error.
