What is the error observed?
Just to confirm..you are copying Fcs from the File gdb into the dataset in sde or the other way round?
Have you tried importing the Feature Class and checked if that works?
Not sure why the Copy/Paste is not working....however you can use the below two tools to copy the FCs along with related data:
Export XML Workspace Document (Data Management)

Import XML Workspace Document (Data Management):
http://resources.arcgis.com/en/help/...0000014s000000
Now import that XML in the File gdb...it will transfer all the data you selected while creating the XML!
