How To Fix CNV_20100034 - &1 -> &2 cannot have participating company codes; see long text

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 034

• Message text: &1 -> &2 cannot have participating company codes; see long text

What causes this issue?

Copying chart of accounts &V1& into chart of accounts &V1& (same name!)
does not make sense.
However if you merge a chart of accounts into an existing chart of
accounts, you may want the accounts and cost elements from the existing
target chart of accounts to take priority in merges.

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

To implement this requirement, proceed as follows:
Create a mapping entry &V1& -> &V2&
Set the <ZK>Copy Rows</> indicator at central chart of accounts level
Set the priority indicator for an account or cost element.
The system then recognizes this scenario as a mere priority scenario.

System Response

If the given scenario is a mere priority scenario and does not involve
any changes within the chart of accounts &V1& itself, it is not allowed
to enter participating company codes.
However the system found that you entered at least the company code &V3&
in the mapping table, which is not allowed.

How to fix this error?

Either change the mapping accordingly or delete the <ZK>Copy Rows</>
indicator at central chart of accounts level from the mapping table.
&ADDITIONAL_HINTS&
Renaming accounts or cost elements is not allowed in a priority
scenario.
