What causes this issue?

The system found that the G/L account &V1& will be converted into &V3&
(according to the mapping). However there is already a secondary cost
element called &V3&, which does not get converted into another value.

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

System Response

In effect, this means that a G/L account and a secondary cost element
are going to be merged (implicit merge). This is not allowed.
The conversion cannot take place.

How to fix this error?

Change the mapping table accordingly.

CNV_20100250 - Details

• The SAP error message CNV_20100250 typically occurs during the process of merging General Ledger (G/L) accounts with secondary cost elements in the context of a migration or conversion project, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there is an attempt to merge a G/L account with a secondary cost element due to a merge in the existing Chart of Accounts (CoA).
  
  Cause:
  
  Merging of G/L Accounts: The error arises when there is a conflict in the mapping of G/L accounts and secondary cost elements during the migration process. This can happen if the system detects that the G/L account you are trying to merge has a corresponding secondary cost element that is also being merged or has been defined in a way that conflicts with the existing mappings.
  Chart of Accounts Configuration: The issue may also stem from the configuration of the Chart of Accounts,
