View Height issue after click of Link to Action

Hi,

We have custom WD ABAP Appraisal application which has 3 links. Click on each link will navigate to new view in same component.

The issue is(we face this only when executed from Portal) when we click on first link say "Create Appraisal" it is not showing in full page. It is displaying in 10% of the page with scroll bar, where as other links i.e. "View Appraisals" shows in full page.

I cant change the setting to display it in full page because it is not first view.

When we run the same application directly from SE80 it works fine.

Any help on this?

Regards,

Satish
