• What is the cause and solution for SAP error message FDT_EXPRESSIONS660 - Mapped target object &1 for step &2 is not in context of nested function ?

  The SAP error message FDT_EXPRESSIONS660 indicates that there is an issue with the mapping of a target object in a nested function context within the SAP system, particularly in the context of the Flexible Data Import (FDI) or Flexible Data Transfer (FDT) framework. This error typically arises when the target object you are trying to map is not recognized as being valid within the context of the nested function you are using.
  Cause:
  
  Context Misalignment: The target object (&1) you are trying to map in step (&2) is not valid in the current context of the nested function. This can happen if the target object is not defined or accessible in the scope of the nested function.
  Incorrect Function Usage: The nested function may not be designed to handle the specific target object you are trying to map, leading to a mismatch.
  Configuration Issues: There may be issues with the configuration of the data transfer or mapping settings that prevent the target object from being recognized.
  
  Solution:
  
  Check Context: Review the context in which the nested function is being used. Ensure that the target object you are trying to map is valid and accessible in that context.
  Review Mapping Logic: Verify the mapping logic and ensure that the target object is correctly defined and that the mapping is appropriate for the nested function being used.
  Adjust Configuration: If there are configuration settings related to the data transfer or mapping, ensure they are correctly set up to include the target object in the context of the nested function.
  Debugging: Use debugging tools to trace the execution and identify where the context mismatch occurs. This can help pinpoint the exact step or configuration causing the issue.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the specific nested function and its requirements regarding target objects.
