Save Local Model as Central Model

Tried something different just to see if this DocumentSaveAs works:
I have a Central model in server
Copied it directly into my local drive
Ran the [Document Save As] from GeniusLoci Package
It works!

But its creating a Central Model from another existing central model
What I want to do is to make Central Model from a Local Revit Model

Tried copying whats done in

but its still telling that the document is not workshared.

Help D:
