Documents do not Open in New Window

Dear DMS Experts,

I have made the settings in DC30 for Workstation application ,and also workstation application in Network for   PDF, WRD, WWI, XLS, ACD, etc,

For PDF, the originals are displayed in a new Windows, but for WRD, XLS, it opens in the same window, even with INPLACE and OUTPLACE settings.

Secondly, We are using Vault - ZCARR  , If i want to edit the Original , it is saying no value defined and also does not bring that in F4 entries.

Is there any customizing missing ??

Lastly, is there a good way to implement dept based hierarchy ? As when i have defined a Hierarchy based on Dept as below, the authorization restrictions not working, as AD1 can also save FIN as its superior document, please guide how to restrict.

                 HME

   ADM                    FIN

AD1 AD2          FN1   FN2

Thanks

Adnan
