multiple session issue

[Former Member]

Hi,

I have created SAP transaction ivews in my portal with SAP Logon tickets to connect r/3. End users are having tendency to open multiple browser window using Ctrl+N. This way they dont have to login many times and can have many portal window open.

The problem here is for each new window opned with Ctrl+n it opens a new session in R3. this way there are so many sessions are opened in R3. Is there any way we can prevent multiple sessions in R3?

Mr. Gu,

I am very interested in the User Exit you were talking about. Can you give me some clue, for example the name of the User Exit or function module of enhancement framework?

Thanks,

I create a customized project for this enhancement

Inside it, I do the validate check for user login sessions

Hi Siddharth,

There is a parameter called login/disable_multi_gui_login

which can be set to value of 1. This will disable multiple gui logins completely. However, if you just want to limit multiple gui logins, set the parameter rdisp/max_alt_modes. You can adjust these parameters in the DEFAULT.PFL file or via transaction RZ10. However, the R/3 system will have to be bounced for these changes to take affect.

If this helps, please consider rewarding points.

Hi Rick.

I also meet with the same problem , situation.

We have tried with parameter

login/disable_multi_gui_login

but it does not work if login come from EP SSO.

When user open backend R/3 from EP SSO, it will not be considered as a new connection, so the parameter validation does not work.

I check the documents. EP has some session management methism to control the too much sessions to backend system.

And in our project, our solution is that we develop a userexit in R/3. When user login in R/3 from EP for more than 1( the number can be changed as u want ) times, the R/3 will tell user that he can only connect to R/3 for one connection, he can go on ( terminiate the old one ) or quit current.

Hi, Jihanong Gu

Would it be possible to send me the outline of the verification procedure you have on your user exit ?

I do not know how I would handle the verification of sapgui coming from the Portal.

Thanks in advance.

You can set a maximum session limit in the backend per logon as a system parameter. I couldn't find it right away, but I remember, that you can set it. The default is 9 "mode" per GUI logon. Your Sys Admin maybe remember better than me.
