Other plants have posted stock and no excise duty group

What causes this issue?

Other plants for the material do not have excise duty tax groups, and
there has been stock posted to the material at the other plant(s).

System Response

You cannot enter an excise duty tax group for this material. A
material has to have been maintained with the same data for all the
affected plants (that is, the same conversion group, unit of measure
group, tax group, etc.).

How to fix this error?

You may have to create a new material, because once stock has been
posted anywhere for the material, you cannot maintain a different or
new excise duty tax group.
