The availability of the PRC_TICK field will vary based on various factors such as asset class and originating source/exchange etc.
If available, it would be for the MarketPrice domain and the service name would depend on how your local realtime distribution server is configured. For Refinitiv's consolidated feed the service name is usually ELEKTRON_DD (or IDN_SELECTFEED for many longer term customers)- but can vary based on how your market data team has configured the service name. You may wish to check with them.
In terms of checking if it would be available for your particular asset class + exchange, you can either raise a Content Ticket with the Refinitiv helpdesk and get advise from a content expert OR you can try using the Data Model Discovery tools Advanced Search facility to check for yourself.
You can enter the FID name or number on the 1st tab and once found, use the 2nd tab to find where it can appear. Brief instructions are provided at the top of that page.
You can also find more information on the Data Model Discovery tool including a Quick Start Guide etc at My.Refinitiv
