Chat transcript: Create/Update with set_entry

Hi Team, 

I am trying to create a Chat Transcript with the set_entry method.
I have tried to create Calls and it works perfect.

But I cant manage to create a Chat transcript.
The singular and plural names are the same chat transcript

Please provide me some suggestion, I am working with sugar 7 but I do not find any helpful material for this module.
I have tried the module names as
Chat transcript
Chat transcripts
Chat_transcript
Chat_transcripts
chat transcript and so on but i still cant figure this out
