Encoded data length exceeds RWF length. Price contribution

Hello guys. Need you help, with price contribution. Here is the situation:

Here is the code:

FieldList nestedFieldList = EmaFactory.createFieldList();
val inavValue = inav.getTargetNavT1().setScale(INAV_SCALE, HALF_EVEN).doubleValue();
nestedFieldList.add(EmaFactory.createFieldEntry().doubleValue(INAV_FIELD_ID, inavValue));

UpdateMsg nestedUpdateMsg = EmaFactory.createUpdateMsg()
        .streamId(postStreamId)
        .name(inav.getEtp().getRic())
        .payload(nestedFieldList);

val id = ++postId;
final PostMsg payload = EmaFactory.createPostMsg()
        .streamId(postStreamId)
        .postId(id)
        .domainType(EmaRdm.MMT_MARKET_PRICE)
        .solicitAck(true)
        .complete(true)
        .payload(nestedUpdateMsg);

consumer.submit(payload, loginStreamHandle);

That`s the current situation. Previously I was preparing field like that:

nestedFieldList.add(EmaFactory.createFieldEntry()
                .realFromDouble(INAV_FIELD_ID, inav.getTargetNavT1().setScale(INAV_SCALE, HALF_EVEN).doubleValue())
);

With that code no errors happened, but we was told that we are sending zeros.

Someone can please tell the correct way to send price as double?

Hello @dkamburov

• What are the version of EMA Java and Java SDK that you are using?
• Which component (ADH Cache, RCC, ATS, etc.) that the application aims to contribute data to?

The "Encoded data length exceeds RWF length" message is generated from the infra backend. The message means the posted value is exceeded PRIMACT_1 (FID 393) field length specification.

You can find more detail of how to contribute data with the following resources/example:

• EMA Consumer - Posting data to Contribution Channel tutorial (for RCC)
• Contributing your data to Refinitiv article (for RCC)
• EMA Java examples ex340_MP_OnStreamPost and ex341_MP_OffStreamPost (for generic OMM Post message)
