Hello Friends,

Please clarify my doubt. I know about three tier str of SAP.

But this line is little confusing. Please explain.

"two application servers on same system"

secondly if a user exist in one application server, does that user automatically exist in other application server also.

Hi Surjit,

It is quite simple.

An SAP R/3 system can have any number of presentantion servers and application servers but only one database sever.Obviously if the user get connected to an SAP R/3 system which has 2 application servers then he can able to access the same.

Hope this will clear your doubt.

yes ,because there's <b>one</b> database for all appl. servers of your sap system

-> user can login on every appl.-server

Hi Surjit!

Did you call TH_POPUP remote?

If you want to create the popup for users in other clients, you have to fill the 'client' import parameter, but if you want to reach other servers, you have to use the RFC-option.

Hi!

CALL FUNCTION 'TH_POPUP'
  DESTINATION none
  EXPORTING
    client         = sy-mandt
    user           = 'XXX'
    MESSAGE        = 'Hello'
  EXCEPTIONS
    user_not_found = 1
    OTHERS         = 2.

Destination has either to be none or the other application server - depending if caller and recipient are on same server or not.

Regards,

Christian

Hi Surjit!

I think, this refers to an other possibility: to run different independent servers (= operating systems) on same hardware. From user (and SAP administrator) it's like seperate hardware, only OS installation is different and real resources are shared.
