This error occurs when you try to save a segment in the Data Warehouse folder where the segment contains elements not compatible with Data Warehouse. To resolve this error, do one of two things:
Save the segment in a different folder
Remove or change the incompatible portions of the segment.
Why does my segment return no data at all?
Possible reasons:
Reverse nesting - for example, nesting a Visitor container under a Visit container.
The report does not support segmentation.
There is no data matching the segmentation criteria.
Why can’t I see the segment I created in the Segment Manager?
Possible reasons:
Some dimensions are available only in Data Warehouse and not in the Segment Manager.
Segment is not compatible with Reports & Analytics.
Segment is checked only for a specific report suite.
A shared segment might have been deleted by another user.
Segments could not loaded due to a data center or Browser Cache issue.
The segment has not been saved.
IP address may be blocked at the user’s end.
Why does the Page Data shown after applying a segment seem incorrect?
Possible reasons:
Rules/Operators are incorrect for the required result.
Incorrect application of containers to the segment.
Traffic variables used to segment are not set properly or are expired.
