My guess is that IBO isn't capable of uniquely identifying each
record. This is the case if either:

-you haven't defined keys in your tables
-you JOIN tables,
-you don't select any key or uniquely indexed field
-KeyLinks is incorrect, or
-KeylinksAutoDefine is false

In general, the find is to identify the field(s) that uniquely
identifies one record and write the name of those fields in KeyLinks.
In quite a few cases, IBO itself can figure out what needs to be the
KeyLinks, and in such cases it is enough to just set
KeyLinksAutoDefine to true.

Good luck,
