Hello, can I get help from you on this ?

I have a problem that dont know how to populate service on incident form if CI has changed - onchange client script would be great for me

We have field cmdb_ci and u_service_ci

When on form is CI which is connected upstreamly to another CI, I cannot get Service on form and dont know how to do it.

Can you help me please ?

Relation I have is like

Service 1--> CI 1 --> CI 2 --> CI 3

If CI 3 is on form, I need to populate Service 1 on u_service _ci field

thank you for your time

/Petr
