Receiving Failure 2673 The source parcel length does not match data that was defined while importing using BTEQ - response (1) by dnoeth

Hi Sudipta,
the error is obvious, you define Load_END as a TIMESTAMP instead of VARCHAR :-)
You should also add a FORMAT to the cast to TIME due to AM/PM:
CAST(:Load_END AS TIME(0) FORMAT 'hh:mi:ssBt'),
And you should add a PACK (if there are no errors in your input data) to get a faster load.
