If I understand correctly, you have 2 dimensions - Product and Location. In the view, you want to use a single product and multiple locations. if yes, you may please create a context filter on Product and a normal filter on Locations. Not sure if you really need a LOD here.
Based off of your question above, I'm not sure you need to combine the two statements. The INCLUDE statement is only used to specify which fields present on your view you want to use in your calculation, not to filter out specific values.
Assuming I'm understanding your question correctly, you should be able to use the FIXED calculation, combined with a filter to remove the locations you do not want to include, and it should work for you.
If this doesn't work in your situation, would you please provide a screenshot or a packaged workbook with a more detailed explanation of what you need? With that we'll hopefully be able to help out more.
I want you to go through the below links where you can get an idea how to use them?
