Sender Agreement problem.. in ID

In Integration Directory, I am able to create all the things namely, Business Services and Communication Channels, Interface Determination and Receiver Determination and Receiver agreement but I am unable to create the Sender Agreement.

Let me explain my scenario : File-XI-File.

I have done all the necessary things like SLD part, Design part etc..

I have gone through the blogs by Venkat on File-XI-File Scenario...

If anybody can guide on this that will be very helpful..

Thanks in advance.

Best Regards,

Mona
