CNV_20200_CHECK053 - Overview

• Message type: E = Error

• Message class: CNV_20200_CHECK - Messages for check functions (company code merge)

• Message number: 053

• Message text: Temporary duplicates possible due to mapping of company codes &1 and &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 &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.
