How To Fix CNV_20100180 - Merge into a country-specific CoA is not possible (&1 -> &2)

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 180

• Message text: Merge into a country-specific CoA is not possible (&1 -> &2)

What causes this issue?

According to the mapping table, you want to transfer the data from the
previous accounts to the country-specific G/L account fields for
operative charts of accounts &V1& and &V3& (fill country-specific chart
of accounts). You specified the same name &V4& as the ID of the
country-specific chart of accounts for both operative charts of
accounts.

System Response

When the country-specific chart of accounts &V4& is implemented, the
master data of chart of accounts &V1& is copied into &V4&. The same
would happen with chart of accounts &V3&, which would result in the two
charts of accounts being merged into country-specific chart of accounts
&V4&.
This is not allowed.

How to fix this error?

Enter a unique name for the country-specific chart of accounts in each
line in the mapping maintenance for old and new charts of accounts for
which you want to implement a country-specific chart of accounts.
