• Message number: 009

What causes this issue?

You may have tried to put a table/view key field in the exclusion
table, but key fields are the basis of Cross-System Viewer comparisons.
If you have made an upgrade and you are reusing a previously-created
exclusion table, it may contain exclusions which in turn contain key
fields.

How to fix this error?

To delete inconsistent entries from older releases (see above):
Go back.
Call the exclusion table again.

Delete these entries.
Save your changes.
You can then make new entries.
