CNV_20200_CHECK055 - Overview

• Message type: E = Error

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

• Message number: 055

• Message text: Implicit merge into target company code &1

What causes this issue?

<DS:TX.CNV_MBT_IMPLICIT_MERGE>Implicit merge</> into target company code
&V1&.
If according to the mapping a company code is converted to a company
code that already exists, these two company codes are merged. If the
existing company code is not included in the mapping, this is an
<DS:TX.CNV_MBT_IMPLICIT_MERGE>implicit merge</>, that is, a merge that
is not defined directly (explicitly) in the mapping, but follows
implicitly from the mapping and the existing company code.
Example: Company code A is renamed into B (mapping: A -> B). However
company code B exists already and is not meant to be changed into
another company code. This would amount to an implicit merge of A and B.
For these implicit merges, the same checks as for explicit merges are
required (mapping: A -> B; B -> B).
We require that all company codes are included in the mapping, which are
part of an identified implicit merge.
