Oracle Error Message
ORA-31531: could not find column string in CDC subscriber view string.string
Reason for the Error
A column was missing in a subscriber view for an imported Change Data Capture subscription.
Solution
It is likely that this view existed before the import operation and import did not overwrite it. Determine whether the imported subscriber view should supercede the original view. If so, drop the original view and retry the import. If not, the subscriber view must have a different name in order to be imported.
