unable to update a record in table using Patch/Put

[JayS04066785221]

I'm trying to update a specific record in a table using the following API

https://docs.servicenow.com/bundle/vancouver-api-reference/page/integrate/inbound-rest/concept/c_Tab...

but doesn't seem to be working. I get a 200 response back so it seems to be processing but the approval state does not change from 'Not Yet Requested' to 'approved' 

body = '{'approval': 'approved'}'

requests.put(

            f"{sf_endpoint_url}/api/now/table/change_request/{sys_id}",

            data=json.dumps(body),

            headers=headers,

            timeout=30

        )

Hi @JayS04066785221 

Is any workflow stopping?

I have tried the exact same steps mentioned by you. The approval field is getting updated.

I am able to modify other fields except for approval state. It seems like i'm missing some mandatory fields but can't figure it out. when i try to create a change request with approved state already, i get the following error but they are all present.

{"error":{"message":"Operation Failed","detail":"Data Policy Exception: \\n\\tThe following fields are mandatory: Pre-change testing, Downtime required, Change model, Validation plan, Remediation plan, IT communication, Planned start date, Reported CI, Planned end date, Implementation plan, Requested by, Short description, Assignment Group, Description"},"status":"failure"}'

From the look of the log. Your custom data policies are restricting.
