• Message number: 048

• Message text: Company code &1 must be indicated; see long text

What causes this issue?

A chart of accounts is always assigned at the level of a controlling
area (rather than a company code), which means that all company codes
that belong to a controlling area have to use the chart of accounts that
is assigned to this controlling area.
Company code &V1& belongs to controlling area &V2&. Because chart of
accounts &V3& participates in the conversion, and because this chart of
accounts is assigned to the controlling area &V2&, all company codes
that belong to controlling area &V2& <ZH>must</> participate. This also
applies to the company code &V1&.
