Hi,Experts:
I was testing the supersession in Sales order under S4-1809 version., but it didn't work ,i follow the steps as below SAP help . As you could see below, when i clicked enter, it jump to below screen but the supersession parts not appeared.
The same parts work well in purchase order. so i think the master data settings should be correct.
Is there any special settings in sales order ? like item category? thanks.
Create a sales order for a part in a supersession chain: Logistics → Sales and Distribution → Sales → Order → Create.
Select the item and choose Enter.
The product selection and availability check are run as background jobs and one or more interchangeable parts, across which the order quantity is distributed, appear in the sub-items.

It works as expected in purchase order:
