Standart ODATA PATCH Method not updating

[dylon_militani]

Hi Guys,

We are trying to use the ODATA API https://api.sap.com/api/sap-s4-CE_BILLINGDOCUMENT_0001-v1/resource/Header PATCH Method for update one field on Billing Document, we are getting HTTP 200 OK, but the field was not updated.

URL: /sap/opu/odata4/sap/api_billingdocument/srvd_a2x/sap/billingdocument/0001/BillingDocument('90000000')

Body(payload):

{
  "CityCode" : "NY"

}

HTTP Method: PATCH

Please, any tips?

Thanks a lot!!!
