How To Fix CNV_20100020 - Line &1 does not copy CoA, while most likely scenario &2 requires this

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 020

• Message text: Line &1 does not copy CoA, while most likely scenario &2 requires this

What causes this issue?

Copying a chart of accounts means that when you change a chart of
accounts (for example from X to Y) you also copy the master data of old
CoA X to new CoA Y. CoA X continues to exist in the system without any
changes. Changes to accounts are made exclusively in CoA Y.
According to the data in line &V1&, you do not want to copy the CoA.
However the most likely scenario &V2& absolutely requires a CoA copy.

System Response

The possible basic scenarios were checked, but none of them fits.

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

How to fix this error?

Check once again if you really <ZH>do not</> want to copy the CoA. Note
also the status of the <ZK>Copy Rows</> indicator.
If the <ZK>Copy Rows</> indicator is set, the master data of old CoA X
is copied to Y when CoA X is converted into Y (and, if necessary,
accounts are merged or renamed), while old CoA X will still exist
without any changes after the conversion.
&NOTE&
It only makes sense to set the <ZK>Copy Rows</> indicator if you want to
change the CoA.
