SAP Portal deactivate "Edit locally"

Hallo together,

in our Portal (7.01) we have integtrated iViews in the detailed navigation, which are iViews for Navigation in Collaboration Room.

Well, the target is no collaboration room yet, but folders (which contain workbooks) that are integrated in a FSDB-Repository in KM-Content.

We use this function to enable the locking function of workbooks (to avoid that two users can check out a workbook at the same time) and also

to keep the original data on a file system.

Now here`s the question: Is there a possibilty to deactivte the edit locally for some folders? A user shouldn`t be able to select the "Edit locally"-function over the context menu of a workbook (see screenshot).

Thanks for your help!

Best regards,

Christian
