HI Navakanth
I thought you have a thread open for this issue?

I would recommend you check the Function Module in the plug-in system to ensure it exists, is generated, etc
Possibly check SLG1; ST22 and SM21 in GRC and satellite system to see if you are getting any further error message deatils. If this doesn't set you down the right path then provide further installation information - support pack, etc
