As documented in sap help，it can fulfill my help but unfortunately it is deprecated. Regardless of this warning I have a try and found it does not work indeed.
Then I am speculating that if the document uploaded is read only, it is for sure that the toolbar will be disabled. So the issue turns to that how could I mark the document to be read only on the fly during uploading.
Since word 2007 the format of MS office follows the so called “Open office” protocol whose specification could be found here.
If you change the file type extension from .docx to .zip and open it with WinRAR, you will find the document is actually a bundle of several single files ( called document part in SAP internal ). The editability is controlled within the file settings.xml.
