Filter Results Question

[andre]

Bernd, Maybe a stupid question , but what means the exclamation maks in the Filter / Expression Results window ?

Greetings, Andre.

A question is never stupid.
In the Filter Test Result dialog the icons mean the following:
OK (green check): entry accessible and does not violate any history.
Warn (yellow exclamation): accessible but violates a history.
Error (red cross): not accessible, file not found
