What causes this issue?

You are copying bill of material items to a network.

System Response

To copy quickly without dialog queries, the BOM items are automatically
allocated to a permitted stock and are assigned a corresponding
account. If a unique stock allocation is not possible, the system makes
a permitted allocation which you can change if you want. Once you leave
the transaction, you can only make changes if a component is not yet
released.

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

The system interprets the dependent requirements indicator from the
material master to determine a permitted allocation.
If only collective requirements are permitted, the items are allocated
to plant stock.
If collective as well as individual requirements are permitted, the
items are allocated to plant stock.
If only individual requirements are permitted, the items are allocated
to project stock first and them sales order stock.If both are not
permitted, due to the (missing) assignment of the network, the items
are allocated to plant stock.
