Error when Closing BW transaction iView from Portal

Hi guys,

I have several Transaction iViews pointing to different BW / ECC systems that are working fine when they are executed.

Problem is when the user clicks on any other folder within portal after running any of these iViews, the following error is displayed:

"Required resource not available".

Then Portal gets frozen and only solution is to close the browser tab and reload portal. Looks like whenever the iView is closed, portal tries to log on again as it is calling the SAP GUI.

Any ideas ?

Thanks in advance !!
