Spain provinces from zipcode

[avilovi]

Hello,

I'm struggling to create filled map with sales by departments in different countries.

In both France and Spain the first two digits of the postal code denote the corresponding department.

So, I created the column
Department = LEFT(Customers[ZIPCODE],2)
I create a filled map visual and put [Department] in the "Location", [Sales] in the tooltip and it works ... for France, but not for Spain.

Spanish departments are projected to the french ones.

So, the sales in the spanish department 19 (Guadalajara) are shown in the french department 19 (Corrèze).

Putting a slicer on the [Country] helps only in a sense that it removes spanish sales from the map of France when "France" is selected.

When "Spain" is selected in the slicer, it just projects spanish sales on the map of France.

I'd ve very grateful for any suggestion how to solve this problem.

Here is a small data sample:

'Customers' table:

ACCOUNTNUM	CITY	ZIPCODE	Country	Department
401000	FUENTERROBLES	46314	ESP	46
402644	BARCELONA	08038	ESP	08
402645	Constanti	43120	ESP	43
403006	BARCELONA	08038	ESP	08
400999	REQUENA	46340	ESP	46
401001	BENIFARAIG	46016	ESP	46
402683	BARCELONA	08041	ESP	08

'Sales' table:

Current sales	ORDERACCOUNT	Year invoiced
183	402644	2023
211	402644	2023
592	402644	2023
708	402645	2022
644	402645	2023
483	402645	2023
966	402645	2023
200	403006	2023
113	403006	2023
50	403006	2023

There is 'one-to-many' relationship between 'Customers'[ACCOUNTNUM] and 'Sales'[ORDERACCOUNT].
