ITS Based Applications on Portal.

Hi we have integrated many ITS based applications on Portal, we are on EP7 SP11. Since we are using transactions ivews for HTML(webgui), the command box/transaction box is visible on the portal. to avoid this we have taken sertian steps but even after we have hidden the command box the purpose is not solved.

If i run the tranx on the portal and if i click F3(which means BACK for R/3) my portal ivew goes to SAP EASY Access Screen.To add more on this i can from here go to SAP Menu and then open any transactions like PA30 etc... for ess

In other words i find using ITS based applications on portal is a serious security threat.

If anyone know how do we restrict the same even if we use ITS based applications on Portal...

then please share with all..
