This is a critical error #144865

regarding the dataset update: a reclamation has been added, and it seems already to be fixed, as it was a critical one. The fix is made in FC 12 R2 Update 1, which is available for downloading now. I will first check this version on my side and will let you know then.

I finally found a Solution to this, apparently i had to Use the sapnco.dll for .NET v4.0 instead of the sapnco.dll for .NET v2.0.50
