Map Report - ERROR: Cannot generate the report. Chart series summary generation failed null

[Brian Lancaster]

We have a filed on our incident form called affected location.  It is of type list and references the cmn_location table.  I have the latitude and longitude set on the location and created a map source but I get the "ERROR: Cannot generate the report. Chart series summary generation failed null".  Is this because it is a list field instead of single select reference field?

The location field you are mapping is a list not a single value?  You may want to include some screenshots of the map configuration.  Without that, debugging is rather challenging.

This is the affected location field.

As for the for the map config I Just set the name table and filed and then click Generate Map Source levels related link.

I've never seen anyone set up a map on a list field. Not sure if that will work.

That is what I figured the response was going to be as I created a standard reference filed in my persona dev instance and it worked fine.  Was hoping for some sort of workaround considering all the time I spent getting the latitude and longitude.
