@Paul here’s how i got it to work , you can test this in your test environment.
Created new Supplier with USD currency
2.Created new Price List in USD with Rate
When you raise a new PO select new supplier , under currency and prices , you will see that the system defaults to standard price list,change this to the newly created price list in USD(you can later link it to the supplier).This should\will populate the item rate when the new item selected.
Thank you a lot @msalim79, very much appreciated. I tried your approach, but all settings were already the same.
Btw I got the solution:
Problem was, that when the price list includes prices for different UOMs, need to check the “Price Not UOM Dependent”.
I’m not sure about the side effects now, because I don’t fully understand the meaning of that switch.
But the prices are now fetched in the PO.
Any ideas what the “Price Not UOM dependent” means?
