Switch to different application server in ABAP program

Former Member — Wed, 28 Jan 2009 11:18:36 GMT

Hello everyone,

I am currently working on some ABAP objects classes and tool programs for additional user administration functionality. We are runnig a SAP ERP system with distributed application servers and active logon load-balancing for users.

I'd like to switch to a different application server from within my program in order to get all relevant information for an active user. So far I only found the function TH_SELECT_SERVER (from the function group THFB) for this, but this uses a separate dialog for interactively switching to another application server.

I could use RFC calls with a lookup table for the destinations of individual application servers, but this would not be as flexible. Also I would have to create some wrapper code for standard functions which are not defined as RFC-usable. So I would rather like to switch to the other server instead.

What I'd like to do instead is switching to another server from a user-related server list without any additional interaction in order to run a function locally on the other server. Does anybody know some function, object method etc. which will do the trick?

Greetings,

Markus.

Did you try transaction SM51?

Hello Thomas,

I think the person who posted wants to automate the process.

Do you think a BDC for SM51 will help?

You're right, so maybe TH_REMOTE_TRANSACTION could be helpful. This is what SM51 uses once the "remote login" button is clicked. In general, some of the TH_* function modules might be helpful here.

Hello Thomas,

Bingo !!!

I debugged the report program RSM51000_ALV & found the sub-routine SM51_USER_CMD.

The SY-UCOMM for our purpose is 'RLOG'. and it utilises the FM 'TH_REMOTE_TRANSACTION' )

Hope this will be of some help to the thread starter.

Hello Thomas,

Thanks for the tip. I had to fix some other things first, so I could try using TH_REMOTE_TRANSACTION only today.

In combination with a filtered list from TH_SYSTEMWIDE_USER_LIST which provides the server destination for each user, it works just fine. Finding a user on the application servers and switching over to the desired server now works in one go.

Thanks a lot...
