Support Note 1245596 should be rewritten

If there is a better place to send this comment, please let me know.

Someone should re-write SAP note 1245596. The explanation of how 'OR' works is just wrong. And while the solution points the user to Nulls, the relationship between null values and the problem is never mentioned.

Also, note 1212097 points to 1196142 via hyperlink, but that link requires a password. I found the article another way but the link should probably be fixed.
