How To Fix CNV_20600_CHECK055 - Implicit merge into target company code for number assignment &1

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20600_CHECK - Messages for Check classes

• Message number: 055

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

What causes this issue?

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