I'm not sure I understand the situation (what's the original, to start with), but 'Daten erheben' means, roughly, 'collect data'. It's not synonymus with 'erreichen'.

Vgl. dazu das Substantiv Erhebung:

I agree with Gibson - it doesn't mean that the endpoint wasn't reached, I think it means data were not collected for that endpoint.

Stimme #1 - 3 zu.

Excellent everyone. Thanks very much for your input!
