Map level "MAPLAYER_1" must have only one geo-characteristic in the rows

Hi all,

When trying to get the web item 'Map' to work in a Web Application (BEx Web Application Designer), I get the following message when I run my app:

Map level "MAPLAYER_1" must have only one geo-characteritic in the rows

(And instead of a map, I see:

"All Map Layers Are Hidden")

I have a 'Table' Web Item with

datasource = a query on an InfoCube with a static-geographical Characteristic (ZCOUNTRY) and 0CALMONTH2 in the rows,

in the columns I have 1 KeyFigure.

and I have a 'Map' Web Item in the same Web Application.

What am I doing wrong?

To make things more strange: When a colleague of mine uses his login, he doesn't get this error when running the exact same Web Application (and on the same laptop)!

Kind regards,

Edwin Jacobs
