¿Qué causa este problema?

You want to change items on the <LS>valid-from</> date.
You either entered this date directly on the initial screen in the
field <LS>Valid from</>, or the system determined the date from the
change number you entered on the initial screen.
As none of the selected items is valid on &V1&, you cannot change these
items on this date and therefore cannot allocate any of them to an
operation.
You have to change the validity period of the items, defined on the
item overview screen by the fields <LS>Valid from</> and <LS>Valid
to</> or the <LS>change number</>.

¿Cómo arreglar este error?

If you want to allocate these items to an operation, make the change
within the validity period of the items.
There are two ways of doing this:
If the BOM has not yet been changed with history (with reference to a
change number), choose the valid-from date of the items as the
<LS>valid-from</> date on the initial screen.
If the BOM has already been changed historically, make the change using
a change number.
Choose a change number which has a valid-from date within the validity
period of the items: the selected items may already have been entered
or changed with reference to a change number.
