Year field missing in EndNote export to bibtex

Question

I am using TexStudio for my paper

I created refrences list using EndNotes 9

In all the references that I have, I can see they all have year

But they year is not showing in some of the references in the .bib file

and therefore it does not show the year in the pdf file.

How to force EndNotes to send Year with other reference info?

Edit

Here is the bib content

@article{RN24,

Output style is BibTeX Export

Edit

I noticed that when refrenece has a field called "Year" it shows ok.

but for some references the field called "Year of Conference" then it does not show !

Now my question is how to add a new field called "Year"

Answer 1

I think I found the solution

Posting it here so other people have the same problem can find the solution

The problem is that conference papers do not have "Year" field.

instead they have "Year of Conference"

To fix this issue.

I went to Edit > Output Styles > Edit BibTex Export

Then Choose "Template" from the left side menu and scrolled down to "Conference Proceedings"

In the "Year" field I chnaged the value to {Year.of.Conference}

That fixed it
