No storage location maintained for order item &2

What causes this issue?

"Kit-to-stock" has been activated in the production scheduling profile
&V3& of order &V1&. This order can therefore only be processed as a
kit-to-stock order in an EWM system. However, no corresponding storage
location has been maintained for order item &V2&.

System Response

During the reading of the master data, this message appears in the log
as a warning. At the time of order release, this message is an error
message and release is terminated.

How to fix this error?

Either change the production scheduling profile in the order header or
enter a storage location that is assigned to a warehouse number managed
by the EWM system in the order item.
