Couldn't choose "service" when create phone-ticket

[huozipan]

When I create a phone-ticket, I couldn't choose "service" which only appear '-'. But I create 2 services before. Something I miss or my understanding is wrong?

You should link customer with service. You could select service only after you choose customer.

Thanks pgandalipov. You are right.

Now I have another question. "service" is not belong to CI?? That is not comfort with itilv3.

I want to create a "service" B, which should be use by another service A. In service Zoom, I couldn't link service A to B.
