Standard production only allowed with ref. to indivual customer stock

What causes this issue?

Direct order creation for a material to be configured is only possible
if it takes place in relation to sales order stock since a configurable
material only allows production for sales order stock. A sales order or
a WBS element can serve as sales order stock.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

You should enter a sales order or a WBS element for account assignment.
