scm deliver command is requesting every time a comment, workitem or change set

I am trying to execute the next command:
scm deliver -r https://MyServer:9443/ccm/ -u USER -P PASSWORD -s WorkSpace_Name
because I want to deliver every change in my WorkSpace to the stream by default. But I receive the next message:

Nombre: Entregar
Informes de participante:
Nombre: Conjuntos de cambios descriptivos
Es necesario asociar un elemento de trabajo o solicitud de cambio con el conjunto de cambios o debe configurarse un comentario.
"It is necessary associate an work item or change request with change set or you must set a comment" 
Problema al ejecutar 'deliver':
Ha fallado 'Entregar'. No se han cumplido las condiciones previas: Es necesario asociar un elemento de trabajo o solicitud de cambio con el conjunto de cambios o debe configurarse un comentario.


I check the options for scm deliver command, and I have not found options related neither comments or workitem. For that I tried using "-c 1020" option (This is my change set name), but I continue with the same problem and same message.

How can I deliver every changes in my Workspace to the stream by default?
Maybe I do not find correctly, Which are the options for deliver in this case?

Note: I could see in JazzNet some articles about that, and the people are using API, or some RTC properties. I am not neither RTC expert or Java expert, for that I try to avoid these practices.

Thank you in advance.
