Yes Puneet,
A custom workflow can be created but my requirement is the palce holder from where the workflow event will be triggered?
is this not available in standard? in case of4.7 version there was a prebooking workflow available in the system.
So my questions are,
1) Where will we be able to put the code to trigger the prebook event?
2) How should we manage to displayed the prebooking requests in portal.
