Would you be able to post a copy of the Tableau Packaged Workbook, or at least the Access table with the geo-data? Are the municipalities in question large or small? (For example, over 50k?), How is Norway spelled or abbreviated in the Data Table (could Tableau not be recognizing the country code for Norway as valid?)
Posting the data you are using, or at least screen shots, would be more helpful in diagnosing the issue.

Hi Steve and thanks for following up on my question.
I have attached an excel file with the Nordic data and a tableau worksheet
showing the results when I try to map it.
- The country codes are correctly understood by Tableau.
- I have changed the meaning of the field municipality in the data to
have the geographic role of County.
- I then try to map one of the data values on the map but somehow
tableau doesn't recognize any Norwegian counties/ municipalities and also
doesn't recognize quite a few in Sweden, Denmark and Finland. This shows in
the 830 some unknowns, but I can't go through these one by one?
What to do?

This is a job for custom geo-coding.
1. I was able to find someone, Peter Juel Jensen, on Tableau Public who already created the custom geo-coded data for the municipalities in the countries you wish to map. Here: | Tableau Public
2. I downloaded them and reassembled them as an excel workbook. There are a number of ways you could do this, you could paste all of it to one big worksheet. I used excel Get Data From Text function, so I ended up with a tab for each country (CSV file).
3. Since I had one tab in the workbook for each country, I used Tableau's Union function to assemble them in Tableau as one functional data table.
4. I built the map in Tableau desktop using the Polygon function.
5. I then opened your data file (2015 Nordic Companies by Size) in the same Tableau desktop file.
6. I blended the polygon data table with your data on the Municipality field and colored the municipalities from the number of the records from 2015 Nordic Companies by Size to verify the blend works right.
FWIW, I would recommend pivoting your data file so that you don't have a separate measure for each employee count bin value.
I might have to attach the samples in separate response, the are roughly 45mb each.
That's beautiful! Could you share the ScandinaviaMaster.xlsx file so that I
can recreate this is in the bigger tableau workfile? Would you also have a
tip on where I could find the same type of solution for Belgium,
Netherlands, Luxemburg, UK and Ireland?

Hi again Steve
I have run into some trouble:
- I refined the view of the map (stepped) and noticed that all the
values for the Swedish municipalities have disappeared (null)
- When I look at the data I see that you have slimmed down the datafile
and removed a lot of the fields. I tried to relink the data file to the
Tableau workbook, but then I get the next problem
- Is it possible to link the Scandinavian municipality data to the
original data fields without running into the next problem: I also seem to
run out of memory even when Tableau is the only thing I have open after a
reboot (see screen shot below). I have 4Gb memory. When I was mapping the
files before I did not have this problem?

I'll attempt to attach here. it's quite a large excel file (41mb).
- Refined view (stepped) values for Swedish municipalities.
I tried to reproduce what you've described and cannot. Can you please provide more detail?
- Slimmed down data file -
Yes, you should be able to simply replace the data file that I've provided with yours. I did take the liberty of reshaping your data, as having so many measures for the different employee bins tends to be problematic from a Tableau analytical approach. Tableau likes 'tall, skinny data' whenever possible.
That said I will attach a new version with the un-pivoted data in another post (cannot attach in a response).
-Memory issue - Yes, here is the probable issue, that geo-spatial data could be Generalized to reduce the number of vertices in the polygons and thereby decrease the amount of the memory needed. Unfortunately, I don't have the resources to do so. You might look into https://gallery.alteryx.com/ for something that might help.
For Belgium and other European countries. Check with the Tableau Public account that I linked to in previous response to see of that user has already created those geospatial data files. Otherwise, check https://tableaumapping.bi/ I recently found UK county TDE data there.
Best of luck!
Really appreciate the time you are putting on this.
Regarding the stepped value all I did was right click on the color legend,
choose edit colors, and clicked stepped colors, see attached picture.
Thanks for the tip on UK counties etc. Would it be possible to share the 41
Mb Scandinavian polygon excel file via dropbox or something the so that I
see how you built it in order to do the same for the other countries? My
email is email@example.com.
Don't know what to do about the memory issue.
Thanks for your help!
