SQL*Loader-00943
incorrect datafile string specified for table string partition string
Cause
The specified datafile is not in the tablespace of the specified partition. Due to use of FILE= keyword on a partitioned table. When loading all partitions of a partitioned table, the partitions must be in the same tablespace. When loading a single partition, the tablespace of the partition being loaded must be the same as the tablespace in which the specified datafile file resides.
