Kernrechtsfrage
Whether the record sufficiently established the onset and degree of work incapacity for pension entitlement.
Extrahierter Entscheid
No; the medical file was not sufficiently reliable to fix the beginning and extent of incapacity.
Extrahierte Begründung
The treating physician's report did not clearly state onset and extent for the relevant period, and isolated assessment of somatic and psychiatric findings was inappropriate. An interdisciplinary examination was required.
