We have integrated SAP R/3 with Portal (EP 6.0). It is windows GUI integration. We are facing following issues with this.
1. When we see the SAP screen in portal, in home page (i.e. SMEN transaction), two buttons in the tool bar area 'Create a New Session' and 'Generates a Shortcut' are disabled. This is not the case when SAP system is accessed directly from SAP GUI.
2. Inspite of the issue mentioned in point-1, it is possible to create a new session by going to 'Systems->Create Session'. But the new sap gui window opened has nothing to show. User has to go to SMEN transaction for seeing the home page. Major problem here is, as soon as user browses to some other page in the portal, this newly opened window goes off.
3. Another major problem is, when user goes to some other page after browsing SAP system and comes back to SAP R/3 page after sometime, inspite of seeing the last seen content in SAP R/3, user always sees the home page for SAP R/3.
Please advice for any solutions.
