Derivation of spec. conditions types by &1 occurs from the article

What causes this issue?

You can only derive the special conditions type according to &V1& from
the article. This is because the &V1& is maintained directly in the
article, and not in the packaging assignment.

System Response

The automatic derivation analyzes the &V1& for the recycling partner
assignment to the article.

How to fix this error?

If you are expecting a different derivation, you must change the
<DS:DE.J_7LKZMFUEL>Content ID Key Art.</> indicator or the
<DS:DE.J_7LKZMINFK>Add.InfoKey Article</> indicator in <LS>Master
Data</> group box, or select a different derivation type.
