Related list edit button missing

[ServiceNowSteve]

Morning!

Yesterday I related the change table to the incident table to see incidents that were created as a result of a change.

The problem now is that I can only relate Incidents to Change by creating the incident from the change by clicking New....I would like to be able to Edit and add existing incidents.

I have looked at the list controls and the "Omit Edit" is not checked.
I have clicked the "Enable Edit" button on the list controls and nothing happens.

Any idea how I can make this work?

stevemunsell,

 I believe change to incident is 1-to-many relationship. You cannot add the EDIT button in this scenario.  as this related list of change to incident is 1-to-many relationship. 

The New or Edit button does not appear on a one-to-many related list

I see, well thanks for the information.

Correct:  You cannot add the EDIT button in this for a 1-to-many relationship. 

 Wrong: I believe change to incident is 1-to-many relationship.

Correct: Change to Incident is many to many relation ship.

I was able to add the edit button on the Incidents cause by change related lists by clicking enable edit button, not sure why you are unable to do it.

because if a change is raised because of multiple incident then we don't need to go back to the incident we can directly add incident from here.
