Multiple picking not allowed for delivery

What causes this issue?

For a TO item with reference to a delivery, you wish to pick a larger
quantity than the quantity requested. This is only possible for handling
units when the picked quantity can be copied into the delivery as the
delivery quantity.

by the system.

In Customizing, you set the WM movement type accordingly.
