Digital Personnel Files in SAP HCM make it visible in SAP Portal ESS/MSS

In the blog http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/28506 a good explaination is wriiten of how a digital personnel file cab be set up using standard funtionalities.

But,

If I understood it well, this feature is very useful for professional users using the SAP Gui.

My question, can we use this feature to display documents to an end-user or a manager via the SAP portal using ESS/MSS. Of course not all documents are visible for the end user (e.g. only appraisals)and other documents are visible for a manager (e.g. appraisals and cost notes). The necessary security must be set.

Can someone give some advice?

Thanks a lot for a reply,

Erwin
