Enable hyperlink in Appraisal Template

Hello,

I have added URL link <a href="url"target=_blank>link test</a> , under template web layout->descriptions.

And I have implemented HRHAP00_LINK and dynamically filling URL. When I test it I can see hyper link but its not opening the desired page.

Can you please guide me how to achieve this.your help is highly appreciated.

Or is there any other way of doing? I want to add hyperlink to call my webdynpro application. Not at header level but under specific tab.

Thanks,

Siri.
