How To Fix CNV_20100094 - Target cost element &2 exists, implicit merge by rename of cost element

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20100 - Messageclass for chart of account conversion

• Message number: 094

• Message text: Target cost element &2 exists, implicit merge by rename of cost element

What causes this issue?

When the cost elements that you plan to merge were checked, it was found
that target cost element &V2& (mapping &V1& -> &V2&) already exists on
the database.
However target cost element &V2& is not used as a source cost element (
&V2& -> XXXX) for another mapping relation.
This means that cost element &V1& is in fact merged with existing cost
element &V2& at chart of accounts-dependent cost element master data
level (CSKA, A level) as well as at controlling area-dependent cost
element master data level (CSKB, B level).

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

This has the following consequences. You need:
to find out if the implicit merge is correct from a logical point of
view
to explicitely include the entry &V2& -> &V2& to the mapping
to consider the priority indicator. If the priority indicator is not
set, it is not clear which settings will take priority when cost
elements &V1& and &V2& are merged into &V2&.

How to fix this error?

<ZH>Regarding item 2:</>
Include the mapping &V2& -> &V2& into the mapping table so that at least
the following entries exist in the mapping table:
&V1& -> &V2&
&V2& -> &V2&
If applicable, any other mapping with target cost element &V2&.
This allows the system to check the merge for logical correctness.
A troubleshooting activity is associated to this activity which supports
you in creating the required mapping entries to resolve the implicit
merges.
<ZH>Regarding item 3:</>
Set the priority indicator for one of the entries for which &V2& is the
target cost element.
&NOTE&
It is possible to do the conversion without setting the priority
indicator. However then you should check the settings in A segment
(master data in chart of accounts, transaction FSP3) and B segment
(master data in controlling area, transaction FSS3) for the relevant
cost element &V2& after the conversion.
&ADDITIONAL_HINTS&
The priority indicator must not be set more than <ZH>once</> for all
merges to a given target cost element. This is also valid for
cross-chart of accounts merges.

• What is the cause and solution for SAP error message CNV_20100094 - Target cost element &2 exists, implicit merge by rename of cost element ?

  The SAP error message CNV_20100094 indicates that during a data migration or conversion process, a target cost element already exists in the system. This situation arises when the system attempts to create a new cost element that has the same identifier as an existing one, leading to an implicit merge by renaming the cost element.
  Cause:
  
  Duplicate Cost Element: The error occurs because the target cost element (identified by &2) already exists in the system. This can happen during data migration when the source system has cost elements that conflict with those in the target system.
  Data Migration Process: The error is often encountered during the execution of a migration project, particularly when using SAP's Migration Cockpit or other data migration tools.
  
  Solution:
  
  
  Review Existing Cost Elements: Check the existing cost elements in the target system to understand why the conflict is occurring. You can do this by navigating to the relevant transaction (e.g., KS01 for creating cost elements) and searching for the cost element in question.
  
  
  Adjust Migration Data: If the cost element already exists and is valid, you may need to adjust your migration data to avoid creating a duplicate. This could involve:
  
  Renaming the cost element in the source data before migration.
  Mapping the existing cost element in the target system to the corresponding one in the source system.
  
  
  
  Use Implicit Merge: If the implicit merge is acceptable, you can allow the system to rename the cost element automatically. However, ensure that this does not lead to confusion or data integrity issues in your financial reporting.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool you are using. There may be specific guidelines or best practices for handling cost elements during migration.
  
  
  Testing: After making adjustments, perform a test migration to ensure that the changes resolve the error without introducing new issues.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as KS01 (Create Cost Element), KS02 (Change Cost Element), and KS03 (Display Cost Element) to manage cost elements effectively.
  SAP Notes: Check for any SAP Notes related to the error message or the migration process you are using. SAP frequently updates its knowledge base with solutions to common issues.
  Data Migration Tools: If you are using specific tools like SAP S/4HANA Migration Cockpit, refer to the tool's documentation for detailed instructions on handling cost elements and other financial data.
  
  By following these steps, you should be able to resolve the error CNV_20100094 and successfully complete your data migration process.
