SAP Error Message - Details

• Message type: E = Error

• Message class: FGL_PRE_CHECK - Pre Transition Check FI-GL

• Message number: 006

• Message text: Real-time integr. CO-FI: Ledger group &1 does not contain leading ldgr &2

What causes this issue?

In the customizing of the real-time integration of CO-FI the ledger
group &V1& is used.

System Response

The ledger group &V1& doesn't contain leading ledger &V2&.
This means that the leading ledger can't act as ledger for CO data for
all company codes.
Background:
In SAP S/4HANA Finance FI and CO share the same persistence for storing
postings: In other words, CO has to store its data in a G/L ledger. This
G/L ledger must be the leading ledger.
The customizing migration program evaluates the customizing of the
real-time integration of CO-FI in order to check whether the leading
ledger contains all CO postings: That is, primary postings from FI and
secondary postings from CO (such as repostings and allocations between
cost centers).
<ZH>After the migration, the secondary postings from CO will also be
posted into the leading ledger</>.

How to fix this error?

Keep in mind that these additional postings into the leading ledger will
affect the data displayed in financial reports.
