Incident form state comparison - OOB field comparison

[snow_beginner]

Hi,

On the incident form we have OOB fields - 'State' (state) and also 'Incident state' (incident_state). I know the 'state' is synced to 'incident_state' but was wondering the following:

1) Why is this 'incident_state' field provided by ServiceNow?

2) If we need to create a new state choice for incident form, should we create in 'state' or 'incident_state'?

3) has anyone ever seen 'incident_state' field being used by a user on any instance?

Thanks.

then that is the field you got to go with.

I have carried out some testing in PDI.

If I create a new choice in 'state' field then the new choice is also visible in the 'incident_state' field.

Now if I create a new choice in 'incident_state' field then 2 things happen:

1) It is not visible on the form in the 'incident_state' field.

2) It is not shown in the 'state' field dropdown (on the 'incident_state' field in config_dictionary there is a special choice list specification.

Does this mean ServiceNow wants us to only use 'state', create new choice in 'state' and never work or display 'incident_state' as it is just a synced legacy field?
