Jeff,

This sounds like bug 893259 "CREATE SNAPSHOT ON TABLE W/ VARCHAR2(4000) TRUNCATES COLUMN TO VARCHAR2(2000)" that's fixed in 8.1.6 and later.

The bug causes the snapshot to be incorrectly created with a varchar2(2000) column instead of the larger column from the base table.

Have you compared the column definitions between the master and snapshot table? If the only difference is that the snapshot has columns of a shorter length than the master table, I should think you'd be able to workaround this by altering the snapshot base table to increase the column length of those columns to match the column lengths of the master table. The refresh should then work properly.

HTH,
