Can i disable the copy to option of orignal file ?

Hi DMS gurus,

In Orignal tab where i am attaching my origanl file (WRD,EXCEL,AutoCAD) , if i select the attach file & right click on that you wiil find copy to.. option. I would like to disable this option.

I am using KPRO server & my data carrier type is "PC" & frontend computrers is "default".

My aim is as per the authorization user can download AutoCAD (DWG) file from DMS in dwg format & other user can not download in dwg format.

If any standard SAP authorization object is availble pls let me know...if no then let me know how can meet this requirement ?

Points should be given.

Regards,

Sunny
