For company code &1 ledger group &2 could not be migrated as default

What causes this issue?

The system can't migrate ledger group &V2& from the customizing of the
real-time integration of CO-FI into the new FINS_CO_DOCT_CC view. The
reason is that this ledger group doesn't contain all those ledgers that
are assigned to CO versions. See <DS:SIMG.FINSV_VERSN_LD>IMG activity
for assigning CO-versions to ledgers</>.

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

System Response

How to fix this error?
