  The SAP error message OL349, which states "Structure & is not a structural data type," typically occurs when there is an attempt to use a non-structural data type in a context where a structure is expected. This can happen in various scenarios, such as when defining data types in ABAP programs, using function modules, or working with data dictionary objects.
  Cause:
  
  Incorrect Data Type: The variable or data type being referenced is not defined as a structure in the ABAP Dictionary.

  Debugging: If the error persists, use debugging tools to trace where the error occurs and inspect the data types being used at that point.
