KUP-04108: unable to reread file string

KUP-04108: unable to reread file string
Cause: The query that is executing requires that a data source for an external table be read multiple times. However, the data source is a sequential device that cannot be reread. Examples of this type of data source is a tape or pipe.
Action: There are a few ways around this problem. One is to rewrite the query so that the external table is referenced only once. Another option is to move the data source to a rereadable device such as a disk file. A third option is to load the data for the external table into a temporary table and change the query to reference the temporary table.
