Using SAS/ACCESS Interface to Oracle to bulkload into an Oracle table that contains indexes using PARALLEL=TRUE will result in the following error:

SQL*Loader-951: Error calling once/load initialization
ORA-26002: Table xxx.xxx has index defined upon it.

The reason for this error is that Oracle's SQL*Loader can't be used on Oracle tables that contain indexes with the option, PARALLEL=TRUE.

To workaround this error, the index can be kept but the option, PARALLEL=TRUE, must be removed. Another option is to keep PARALLEL=TRUE and add the index after the bulkload is complete.
