@haylau ASM is not meant to be an ERP. I think this is the common misconception about what ASM is.
Here are some use cases in my view of ASM
Say you have 2 warehouses, one in Germany and one in Switzerland. Someone orders a widget from Switzerland. The ASM system figure out where the widget ships from. Say in Switzerland to Switzerland you offer free shipping. But from Germany to Switzerland you offer 3 euro shipping. The ASM system figures out where the product ships from and charges that amount.
Another use case in my mind is say you have a store in Bern and a store in Munich. I am in Munich, I want to buy widget x, I get on your site and see if widget x is available at the Munich store.
