Hello @kesava.rao.malla

Do you use RFA and would like to receive Tib messages e.g. image, update messages which each contain only 6 fields e.g. BID, ASK of a RIC? If yes, it is impossible because TIB API which is one part of legacy interface(MarketData interface; SSL connection) does not have the feature to specify fields. All published fields are sent to the application. I recommend you use Elektron Message API(EMA Java or C++) which is easy-to-use, open source and provides View feature which allow you to specify your preference fields as shown in the figure below:

Moreover, EMA has several advantages comparing to the legacy interface of RFA. For more details, please refer to Why Migrate from RFA to EMA API? VDO
