ORA-31527: could not find source column string for CDC change table string

.string

What triggered the Error:

A source column was missing for an imported Change Data Capture change table.

What should we do to fix it:

Drop the imported change table because it is invalid. Verify that the schema containing the source table was included in the original export. If needed, perform the export again, including the schema of the missing source table.
