How to update read only fields via API connector

[swright2]

Hi, 

With our connector to ServiceNow, our clients are wondering why when they run a sync job from our platform to update fields in a ServiceNOW table, that nothing is updated in rare situations. 

We receive a status of 200 from you, and the reason the field updates are not occurring is due to these particular fields in the ServiceNOW table being read-only.  Is this expected behavior, and is there a solution for this beyond our clients having to create ACLs?

You need to make that field editable for the clients so that they can update it.

Well, these are fields in their own ServiceNow orgs.  So what you're saying is that there's no way for an API connection to update a read-only field's value on a table in ServiceNOW?  Is that correct?

Right. If a field is marked as readonly via ACL or at dictionary level, it can't be updated. If it is just at UI policy level, it can be updated via API.

Got it.  Thank you very much for clarifying @SanjivMeher
