Summary :
When using SAP GUI for HTML with ~webgui_simple_toolbar enabled, exiting the session results in the deletion of all cookies, including SSO cookies, which may be undesirable in a portal environment. This issue occurs due to the Session Command LogOff mechanism in ITS versions up to ITS 6.20 patch level 25, NetWeaver 2004 ITS 6.40 BSP 20, and NetWeaver 2004s ITS 7.00 BSP 15. The recommended resolution is to import the latest ITS patch level or Basis Support Package to rectify this behavior.
