Writing to AF Table through PI Web API
Currently PI WebAPI provides only the method UpdateData /Put Tables (https://techsupport.osisoft.com/Documentation/PI-Web-API/help/controllers/table/actions/updatedata.html) to insert data into an AF table and this method requires the entire table data to be sent in the request and it is not currently possible to simply append new rows. It is inconvenient to update the entire table content always as you have GET the current data from the table, add in new content and then use the UpdateData / Put method to save the entire table. As the AF tables get larger, this would cause more network traffic and more error prone. We would like to have a method to augment AF Table data.
