Hi Sathish,
You can use Business Service or Business Component as IDoc sender component.
Do the following step:
1. Open ID
2. Double Click or Open the Business Service
4. Edit the BS
4. Go to context -> Adapter-Specific Identifiers
5. In IDoc Adapter -> Logical System -> Enter a Logical System name
Ensure the LS name you provide here in step 5, is the same LS name you are using in backend we20 while creating partner profile.
It should work now.
Thanks,
Souvik
