• Message number: 053

• Message text: Temp. dupl. possible due to mapping of comp.codes for no. assignm. &1, &2

What causes this issue?

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