• Message text: Temporary duplicates possible due to mapping of company codes &1, &2

What causes this issue?

<DS:TX.CNV_MBT_TEMP_DUPLICATES>Temporary duplicates</> possible due to
mapping of the company codes &V1& and &V2&.
According to the mapping, you plan to convert company code &V1& into
&V2&. However, company code for number assignment &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 code &V1& is
converted at a point in time when company code &V2& has not yet been
converted. If temporary duplicates are likely to occur, the conversion
programs must be generated in a different way.
