¿Qué causa este problema?

You want to change the item(s) 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 the selected item(s) is/are not valid on &V1&, you cannot change the
item(s) on this date, and therefore cannot create an allocation to an
operation.
You have to make any changes to an item within the validity period of
the item, which is defined by the fields <LS>Valid from</> and
<LS>Valid to</> or the <LS>change number</> on the item overview.

¿Cómo arreglar este error?

If you want to allocate the item(s) to an operation, make the change
within the validity period of the item(s).
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 item(s) as the
<LS>valid-from</> date on the initial screen.
If the BOM has already been changed with history, make the change with
reference to a change number.
Choose a change number with a valid-from date which lies within the
validity period of the item(s): the selected item(s) may already have
been changed or entered with reference to a change number.
