• What is the cause and solution for SAP error message FDT_EXPRESSIONS608 - Result is not of type table: only single select allowed ?

  The SAP error message FDT_EXPRESSIONS608: Result is not of type table: only single select allowed typically occurs in the context of using expressions in SAP's Field-Based Data Transformation (FDT) or similar environments where data manipulation is performed. This error indicates that the operation you are trying to perform expects a single value or a single record, but the result is not in the expected format (i.e., it is not a table).
  Cause:
  
  Incorrect Data Type: The expression or function you are using is returning a result that is not a single value or record, but rather a table or a set of records.
  Misconfiguration: The configuration of the data transformation or the query might be set up incorrectly, leading to an unexpected result type.
  Logical Error: There might be a logical error in the way the data is being queried or transformed, leading to a mismatch in expected and actual results.
  
  Solution:
  
  
  Check the Expression: Review the expression or function you are using. Ensure that it is designed to return a single value or record. If it is supposed to return multiple records, consider using a different approach or function that can handle multiple records.
  
  
  Use Single Select: If you need to retrieve a single record, ensure that your query or selection logic is set up to use a single select statement. This might involve using aggregate functions or filtering conditions to ensure only one record is returned.
  
  
  Debugging: Use debugging tools or logs to trace the execution of your expression. This can help identify where the result is being generated and why it is not in the expected format.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific function or expression you are using. There may be specific guidelines or examples that can help clarify the expected input and output types.
  
  
  Testing: Test the expression in isolation to see what type of result it produces. This can help you understand if the issue lies within the expression itself or how it is being used in the broader context.
