How to choose a stock location / warehouse?

Exact Online gives you the option to make multiple warehouses. If you like to only show stock from specific warehouses, you can do so with the Connector settings. 
Go to "Administration" -> "Settings". Than click on the tab, "Connector settings". Scroll down to the bottom of the page, until you reach "Warehouse used for stock".

Here you fill in the warehouse code, the same way it is named in Exact. If you like to add multiple warehouses you can do so by adding a semicolon (;). Make sure that you don't use a space.
