Hello @shenping22975

Thank you for contacting us. Technically, a Refresh Message contains a complete set of data on that item. If the application subscribes to all field data (a default subscription), a Refresh Message contains all fields that are available in that RIC.

However, each RIC has different field behaviors based on its exchange, data feed, and data provider. Some RICs may not provides some FIDs for the consumers because the exchange does not send them. The API just receives incoming data and sends it to the application "as is".

I admit that I am not a data expert, so I cannot answer this question directly. I highly recommend you contact the Content support team to verify if FID 136 is available on your interested RICs. You can contact the team directly via the https://my.refinitiv.com/content/mytr/en/helpandsupport.html website.
