Message text: More than one CoA is converted; CoA-independent mapping is not unique
More than one chart of accounts is converted.
The chart of accounts dependent mapping for accounts and cost elements
is ambiguous (not unique).
This means, that in the mapping e.g. the old account number &V1& exists
twice in (at least) the two conversion relevant charts of accounts &V2&
and is converted into the different target accounts &V3& and &V4&.
Warning
During the conversion of individual tables or table fields without

correctly convert those ambigious accounts, as the related chart of
accounts can not be identified.
