MRN News: how to use MRN_TRNA?

We downloaded Elektron SDK - C/C++ - 1.1.0 - Windows and the examples from https://developers.thomsonreuters.com/system/files/EMA%20Tutorials.zip

We took the example #5 (MRNConsumer) and changed just one line

consumer.registerClient(ReqMsg().serviceName("ELEKTRON_DD").name("MRN_TRNA").domainType(MMT_NEWS_TEXT_ANALYTICS), client);

We have the following screen:

and then nothing else happens. What's wrong? What should we do?

Thanks

PS. If we use MRN_STORY instead of MRN_TRNA it works like a charm and we receive data.

Hi @mauro.medizza

How long do you leave the example running when requesting TRNA ?

MRN_TRNA items/updates are usually issued less frequently than MRN_STORY items...

Try running the NewsAnalytics GUI Viewer Example (MRN) from this page - found under the ELEKTRON SDK - JAVA - SAMPLE APPS section.

If you see MRN_TRNA in the above GUI viewer but not with the tutorial then please report back here.

UPDATE: I just ran the C++ MRN tutorial requesting MRN_TRNA and a few seconds after the initial Refresh, I do see Updates with TRNA items.

Umer, you are absolutely right. Sometimes it is enough to wait a little bit. We do receive MRN_TRNA items but less frequently than MRN_STORY. Thank you!

By the way, we have tried other two keys without success

1) MRN_TRSI

and

2) MRN_TRNA_DOC

Do you happen to know how to fix these two errors in order to use MRN_TRSI and MRN_TRNA_DOC?

Thanks
