This typically occurs when there is an attempt to use a field with an internal type that SAP does not recognize or support in the context of the operation being performed.
  Cause:
  
  Unsupported Data Type: The field in question may have been defined with a data type that is not compatible with the operation or function being executed.
  Custom Development: If the table or field is part of a custom development, it may have been incorrectly defined or not aligned with SAP's standards.
