Hi Haresh,
As the message on the dialog says, the two parts must be in two different models, and only the C-term carbon of one and the N-term nitrogen of the other (exactly two atoms) should be selected.  I can't tell if any of those are true from your screen shot.   Make sure they are two different models and hide ribbon (e.g. Actions… Ribbon… hide) so you can see the backbone atoms and make sure only those two atoms are selected.  Possible problems may be you have >2 atoms selected or the wrong atoms, for example, both are at the C-term.
