Webgui Logon Load Balancing

Dear Friends,

We have configured Webgui and we are able to login through Webgui and

run transactions. We are using SAP ECC 6.0 with two app. servers. And

also configured two logon groups (R3_SERVER_GROUP1,R3_SERVER_GROUP2).But

when we provided Load Balancing=R3_SERVER_GROUP1 in

service /default_host/sap/bc/gui/sap/its/webgui

logon load balancing is not happening. Later we published services through tcode

SIAC_PUBLISH_ALL_INTERNAL.

Kindly guide in this regard

Regards

Sumeet Kapur
