Multiple acctg princ. in CO (COGM): BAdI implementation found

What causes this issue?

Instead of using the <ZK>Multiple Accounting Principles in Controlling
(COGM)</> function with the <ZU>ledger approach</>, you are using the
accounts approach which is not supported in SAP S/4HANA. You have
<DS:SIMG.BADI_FCML_ACCOUNT_MODIFICATION> implemented a BAdI</> that
could do such a mapping.

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

System Response

The mapping of a cost element to a different G/L account is not
supported. The account used must be identical in Controlling and
Financial Accounting.

How to fix this error?

Please delete the BAdI implementation.
