When an AXSMOD is used, Teradata FastLoad will pass the checkpoint value as an attribute to the AXSMOD for its possible use. The attribute value will be a string containing the ASCII encoding of the decimal textual representation of the checkpoint value. A value of “0” indicates that Teradata FastLoad is not using checkpoints. A file opened by an access module instance for which the CHECKPOINT_INTERVAL attribute is “0” will not receive a File Get Position request.
