This error typically arises in the context of using the SAP Fiori Data Transformation (FDT) framework, particularly when defining expressions or data mappings.

  The error occurs when:
  
  A data object is referenced that is not of the expected table type.

  Debugging:
  
  Use debugging tools to trace the execution flow and identify where the data object is being set or modified. This can help pinpoint the source of the issue.
  
  
  
  Consult Documentation:
