Multiply subtotals between 2 matrix depending on different categories

Hi, OscarDOSSANTOS 

Because you did not establish a relationship between the two tables, So there is a problem.

You need to create two table and use the field in your table visual instead of original table field(country and product), then you can get the correct value.

Like this:

Table = DISTINCT(Forecast[Country])

Table 2 = DISTINCT(Forecast[Product])

Did I answer your question ? Please mark my reply as solution. Thank you very much.
If not, please feel free to ask me.
