Update single record field

Yes, we can update the single record field by passing the updated data to the "Write Record" smart service in the process model, It is necessary to pass the primary key of the record otherwise it will write a new record to the database.

You can refer to this link - https://docs.appian.com/suite/help/23.1/Write_Records_Smart_Service.html



This way you can modify record data and pass it to the process model containing the write record.

The reference you posted explains exactly that. Do you have any more specific question?
