To support Teradata TPump restart operations, the INMOD routine must support checkpoint operations, as described in The Teradata TPump/INMOD Routine Interface.

If an INMOD routine that does not support the checkpoint function is used, the job may encounter problems when Teradata TPump takes a checkpoint.

By default, Teradata TPump takes a checkpoint every 15 minutes. The Teradata TPump checkpoint function can be bypassed by specifying a CHECKPOINT rate of zero in the BEGIN LOAD command; that way, the job completes without taking a checkpoint.

Though this would nullify the Teradata TPump restart/reload capability, it would allow an INMOD routine that does not support the checkpoint function to be used.
