This button "Related orders" will show a list of all related orders of the vendors side (Related Purchase Orders) of the active Sales Order.

The german Text is mis-Spelled "Zugeordnete Aufträge" - that would mean "related Sales Orders"

In english, you differentiate
- Sales Orders
- Purchase Orders

The translation of them in german, used throughout D365, is
- Auftrag
- Bestellung

The button therefore needs to be spelled " Zugeordnete Bestellungen" - which is consistent with the button next, ControlName=ButtonPurchTable, name is "Bestellung"

Thanks for fixing
