Ledgers 
Ledgers represent a subset of the database in which the financial statement items in the consolidation are stored.
You define the ledger in the Implementation Guide, under Master Data

Set up ledgers.
Ledgers are identified by a two character ID. As a standard part of the consolidation sub-application, SAP delivers Ledger 10 with the ledger currency USD. This currency can be changed to one that is relevant for you. By copying Ledger 10 as a template, you can create additional ledgers with different group currencies.When performing a consolidation we recommend that you use the following settings:
- Always specify table FILCT as the totals table.
- If data from the Special Purpose Ledger application is to be updated realtime in the ledger, you must select the indicator Ledger posting allowed.
- The indicator Write line items allows you to access individual SL postings from the standard reports. When you decide whether or not the line items are also to be included, make sure you take into consideration the size of the data resulting from it.
- If you select the indicator Rollup allowed, you can execute rollups from other SAP databases.
- Do not select the indicator Maintain d/c indicator for consolidation ledgers. This indicator is used exclusively for the consolidation staging ledger (as the basis for the periodic extract from FI).
- Do not select the indicator Set up balance carry forward for consolidations. The balance will be carried forward automatically via a separate automatic balance carry forward program.
The automatic balance carry forward is used exclusively for additional ledgers in consolidation.
- If you select the indicator Productive, it has the following effects on the deletion of data:
- You cannot delete the transaction data in the ledger using the menu options Preparing for Production

Delete transaction data in the Implementation Guide.
- When you delete totals records using the menu options Indiv.Fin.Stmts
®
Delete in the consolidation menu, a confirmation prompt referring to the ledger productivity appears.
- To ensure the entire functionality of the consolidation application, you need to set the transaction currency, the company currency as well as the ledger currency.
- If you also want quantities to be processed in consolidation, you must indicate this as well. The field Store add. quantities does not have a function for consolidations.
- In the step Extras

Consolidation info, you must also define, with regard to the ledger, whether the consolidation is a legal consolidation or a business area consolidation.
If you want to be able to copy from an already existing ledger to the new ledger, you must indicate that here as well.
In the following instances you will need to use various ledgers for the consolidation:
- when the subgroups have different currencies
- when updating both legal consolidations and business area consolidations in parallel
For more information on this topic, read the documentation "FI Preparations for Consolidation in the FI-LC and EC-CS Systems".
Company Maintenance
You assign companies to a ledger in company maintenance. Several companies are usually maintained in a single ledger. A company can be stored in various ledgers.
If you want to store a company in an additional ledger, you can assign that company to the new ledger using the menu option Master data

Change. Afterwards, the company will exist in both ledgers.
Based on the data stored in company maintenance, information regarding the fiscal year variant as well as whether or not data entry should take place in group currency is stored per ledger.
