BID_1 ASK_1 fields not updating via Enterprise Message API (EMA) Java Edition

erki.joekalda

We have a problem with Refinitiv Enterprise Message API (EMA) Java Edition (Implementation-Version: emaj3.6.1.L1.all.rrg).

We are requesting 'BID', 'BID_1', 'BID_2', 'ASK', 'ASK_1' and 'ASK_2' fields from IDN_SELECTFEED source with DACS user XYZ.

The first refresh message brings all requested fields (as expected) but following update messages comes only with BID and ASK values.

Old API (JSFC 3.5) is working differently, we always receive all fields updates including 'BID_1', 'BID_2', 'ASK_1' and 'ASK_2' fields. There we request data with DACS user YZX.

For example: RIC 'EUR='

OmmArray array = EmaFactory.createOmmArray();

array.add(EmaFactory.createOmmArrayEntry().intValue(22));

array.add(EmaFactory.createOmmArrayEntry().intValue(23));

array.add(EmaFactory.createOmmArrayEntry().intValue(24));

array.add(EmaFactory.createOmmArrayEntry().intValue(25));

array.add(EmaFactory.createOmmArrayEntry().intValue(26));

array.add(EmaFactory.createOmmArrayEntry().intValue(27));

ElementList view = EmaFactory.createElementList();

view.add(EmaFactory.createElementEntry().uintValue(EmaRdm.ENAME_VIEW_TYPE, EmaRdm.VT_FIELD_ID_LIST));

view.add(EmaFactory.createElementEntry().array(EmaRdm.ENAME_VIEW_DATA, array));

EmaFactory.createReqMsg().serviceName("IDN_SELECTFEED").name("EUR=").payload(view)

All following UpdateMsg come for BID and ASK only, but _1 and_2 remain stale.

Question: Why don’t we receive updates for 'BID_1', 'BID_2', 'ASK_1' and 'ASK_2' fields in new API?

Hi @erki.joekalda

EMA does not Ripple the fields i.e. copying BID into BID_1 etc.

The EMA does NOT ripple fields on behalf of the consumer application. The OMM FieldList concept supports rippling. However, the FieldList class does not cache, so it cannot ripple fields.

It is the responsibility of the Consumer application to ripple the Fields.

Please see example series200\ex240_MP_RippleFields which demonstrates this technique.
