I had a case recently where my client contacted me that the Foreign Trade FastTab disappeared from the Sales Order page. Since the only things changed recently was Wave 2, it was easy enough to make the connection.
Foreign Trade tab before Wave 2.
It turned out that the Application Area for the fields inside the Foreign Trade tab have been changed from Basic to BasicEU.
If we look at the Application Area, we can see that Microsoft added some new localization Application Area and reassigned some of the fields into it.
If your environment is not part of the localization, the fields will just disappeared from the pages after the update.
To fix this, you can either create an extension to modify the Application Area or you need to enable that specific Application Area.
Since the Foreign Trade is part of Basic EU, it means I need to enable Basic EU Application Area. How do we enable it ? The only way that I know is by using the Configuration Package. Use table ID 9718 – Application Area Setup, export the data, change it to true, import, and apply it. Restart your browser and the Foreign Trade tab will reappear.
The only downside is that the Basic EU is applied to not just the Foreign Trade. If you search for BasicEU on the Base Application source, you will get 329 results. Other stuffs may also show up in the future update as well.
I don’t believe that enabling this will cause any big issue. You will probably end up seeing more stuffs on some pages.
