How To Fix CNV_20211_CHECK054 - Implicit merges due to mapping of companies

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20211_CHECK - Messages for check functions (company conversion)

• Message number: 054

• Message text: Implicit merges due to mapping of companies

What causes this issue?

There are <DS:TX.CNV_MBT_IMPLICIT_MERGE>implicit merges</> due to the
mapping of the companies.
If according to the mapping a company is converted to a company that
already exists, these two companies are merged. If the existing company
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.
Example: Company A is renamed into B (mapping: A -> B). However company
B exists already and is not meant to be changed into another company.
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 companies are included in the mapping, which are
part of an identified implicit merge.

How to fix this error?
