Hi Vijay,
your question is way too vague. I don't lock this thread because I see you are a fairly new on the SCN forums. Please take the time to elaborate on your problem in detail. You can refer to this blog to understand better how a discussion should be structured, alternatively take a look at one of my discussions:
Asking Good Questions in the SCN Discussion Spaces will help you get Good Answers
One of my posts as example: http://scn.sap.com/thread/3504407
Also please always consult transaction ANST (in case you have the technical prerequisites) to rule out that the error cause is an easy to solve standard error:
What is ANST....and why aren't you using it?
Cheers, Lukas
