Analytic functions in teradataml provide one or more optional arguments of the form <data>_sequence_column to make functions produce deterministic results. This feature is not supported.

If an analytic function is executed with this argument, the function fails with the following error:

Failure 9134 QGInitiatorExport: 24582: (b579e55a-b5b7-4114-9bf6-0000000
002a5) ForeignFunctionDataExec : MLE_ERR: The supplied statement could not be
completed due to an internal error at a database worker node. Please contact support at Teradata.

To avoid this error, execute the function without the argument <data>_sequence_column. The impact of removing this argument is that the analytic functions may not produce deterministic results.
