System Response

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

How to fix this error?

Specify a ledger that is within the customer's name space.

If needed, create a new ledger in the Self-Service Configuration in the
Define Consolidation Ledger work step.
When creating your own ledger, ensure that you use the prefix C in
accordance with the naming convention.

If needed, go to Customizing of Consolidation and create a new ledger.
There you can use &V1& as the reference ledger.
If you have already made ledger-related settings in Customizing, or you
have posted to ledger &V1&, you can convert this data for the new ledger
using program FICRLD00. See SAP Note 127085.

• The SAP error message G00013 indicates that you are trying to use a ledger that is in SAP's namespace, which is not allowed. SAP reserves certain namespaces for its own use, and any attempt to create or modify objects in these namespaces can lead to errors.
