Making Settings for Ledgers
In General Ledger Accounting, you can use several parallel ledgers. You do this to produce financial statements according to different accounting principles, for example. You create a ledger for each of the general ledgers you need. You must check the settings of your leading ledger even if you do not use parallel ledgers.
You make the settings listed below in Customizing for Financial Accounting (new) under Financial Accounting Global Settings (New) → Ledgers → Ledgers.

1. Define Ledgers for General Ledger Accounting
Define your ledgers and designate one ledger as leading ledger (see also Ledgers).

When you create a ledger, the system automatically creates a ledger group with the same name.
2. Define Currencies of Leading Ledger
You can define a second and third parallel currency for your leading ledger for each company code.

For more information, see Parallel Currencies in Parallel Ledgers.
The following settings are optional:
3. Define and Activate Non-Leading Ledgers
If you use parallel ledgers, define your non-leading ledgers. If necessary, create alternative additional currencies or an alternative fiscal year variant.
4. Assign Scenarios and Customer Fields to Ledgers
Here you can assign the following to your ledgers:

In versions, you define general settings for the ledger that are fiscal year-dependent. You specify whether actual data is recorded, whether manual planning is allowed, and whether planning integration with Controlling is activated.
5. Activate Cost of Sales Accounting
Activate cost of sales accounting for your company codes if required. If you do this, the functional area is derived and updated for postings in these company codes. For information about the prerequisites for cost of sales accounting, see the documentation for this IMG activity.
6. Define Ledger Group
You can combine any number of ledgers in a ledger group. In this way, you simplify the tasks in the individual functions of General Ledger Accounting.

For more information, see Ledger Groups.
