• Message class: CNV_20000 - Messages for fiscal year change

• Message number: 144

• Message text: Fiscal Year variant used only in non-leading ledger

Fiscal Year variant used only in Non-leading ledger
In a system where General Ledger Accounting (new) is active, fiscal year
variant assignment to a company code and ledgers can be defined at two
levels:
1. Assignment to company code.
2. Assignment to company code and non-leading ledger.
If you want to convert the data only related to the shortened fiscal
year variant that is assigned to a company code and non-leading ledger
combination (not assigned to any company code and leading ledger
combination), this scenario is not covered by the transformation
solution Fiscal Year Conversion.

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