    Hello @rkumar

    You can use Views feature to limit incoming payload of Refresh and Update messages containing only your preference fids. Using a view, a consumer requests a subset of fields. Then, only the requested fields are sent to EMA application as the diagram shown below:

    For more details, please refer to Section 3.2.3 Views in API Concept Guide

    Note: ADS supports only field numbers(field names are not supported) and Level 1 data(Market Price) domain for Views feature.

    You can find the example of using Views feature in consumer.series300.example360__MarketPrice__View application shipped with Elektron SDK Java package. The example output running the application to request fid no.22(BID) and no.25(ASK):

    Hope this help.
