What causes this issue?

<DS:TX.CNV_MBT_TEMP_DUPLICATES>Temporary duplicates</> possible due to
mapping of the companies &V1& and &V2&.
According to the mapping, you plan to convert company &V1& into &V2&.
However, company &V2& exists already and will be converted as defined by
the mapping to &V3&. In this case, temporary duplicates may occur in the
database if company &V1& is converted at a point in time when company
&V2& has not yet been converted. If temporary duplicates are likely to
occur, the conversion programs must be generated in a different way.
