the advises that you gave didn't work. What i did now is that I took a existing PO, added the products where it go wrong and put the other products in the PO to zero, update it and checked as incoming. So there were to much product in stock but the incoming products were gone.
I did correct the products that were to much in stock.
Good to know that you were finally able to manage this issue yourself.
Alternatively, FYI, there is a tool in ATUM Settings to recalculate all the calculated sales properties in bulk for all your products at once that should do the trick too.
I was thinking, for guys like me, who own a real shop and a webshop (what is one and the same), maybe it is an idea to add a kolom(s) with products that you have in the shop and what you have in the stock room. That makes it easier for a shop owner to check his total stock and he doesn't have to walk from the stockroom to his shop and back.
What's a kolom, please? Perhaps you meant column?
Anyway, you can actually do so by using our Multi-Inventory add-on. So you can create an inventory for your online stock and another one for your physical store stock. And handling them separately. They also will be displayed in Stock Central in separated rows under their product. 😉
