Creating an Extension Ledger for Profitability Analysis with SAP S/4HANA Finance

For some functionalities in margin analysis with SAP S/4HANA, you’ll need an extension ledger to store predictive data.

 

An extension ledger sits on top of a ledger, as shown in the figure below.

 

Relationship between Extension Ledger and Leading Ledger 

Let’s consider an example: When you post a document in leading ledger 0L, it won’t be posted in extension ledger EL. Likewise, when you post a document in extension ledger EL, it won’t be posted in leading ledger 0L. When you run a P&L and balance sheet report for leading ledger 0L, you’ll only see documents that are posted in leading ledger 0L; however, when you run a P&L and balance sheet report for extension ledger EL, you’ll see both postings from leading ledger 0L and extension ledger 0L. All non-generally accepted accounting principles (GAAP)–relevant postings occur in extension ledger 0L. Anything GAAP-relevant will be posted in leading ledger 0L. There is a strict separation of these two ledgers.

 

An extension ledger can’t live on its own; it always references a standard ledger. The extension ledger inherits the basic settings of the underlying ledger, such as assigned currency types. Let’s see how extension ledgers are created.

 

Create an Extension Ledger

Extension ledgers are created in financial accounting via the configuration path: Financial Accounting > Financial Accounting Global Settings > Ledgers > Ledger > Define Settings for Ledgers and Currency Types. By pressing F5, you can create an extension ledger, as shown in the next figure.

 

Creating the Extension Ledger

 

For this example, we created extension ledger EL by maintaining the following criteria:

Ledger

Enter the name of the ledger. The name has two characteristics (for this example, extension ledger EL).

Leading

If you are creating a leading ledger you need to check the checkbox in this column.

Ledger Type

Choose from two ledger types. One is a standard leger, which stands alone, for example, 0L or LC for local accounting. The other is an extension ledger, or one that references a standard ledger (chosen for this example).

  • Ledger Type: Defines how the extension ledger can be used. To use the extension ledger for predictive accounting in margin analysis, choose Line items with technical numbers/no deletion possible.
  • Underly: In the Underlying Ledger column, define which standard ledger the extension ledger is referencing (in this example, ledger 0L is the reference ledger).
  • Pstgs Not Allwd: Select this checkbox to prevent the extension ledger from accepting manual postings. This setting isn’t mandatory for using predictive accounting in margin analysis. It’s selected in this example to make sure that all data in the extension ledger is derived from transactions in SAP S/4HANA and that there are no accruals or predictions entered manually.

Company Code Settings in an Extension Ledger

After creating the extension ledger, you need to check the company code settings. In the Dialog Structure on the left side of the screen shown in the next figure, open the Company Code Settings for the Ledger folder. Because the reference ledger for the extension ledger is ledger 0L, the extension ledger is automatically assigned to all company codes in the system that have ledger 0L. Therefore, you don’t have to do anything except check that company code Z100 has an entry for Ledger EL.

 

Check Company Code Settings for the Extension Ledger

 

Assign an Accounting Principle to the Extension Ledger

Next you have to assign an accounting principle to the extension ledger, which will be the same accounting principle as the reference ledger is assigned to. In the Dialog Structure on the left side of the screen shown below, open the Accounting Principles for Ledger and Company Code folder. Press F5 to create a new line for Accounting Principle LG.

 

Assign the Accounting Principle to the Extension Ledger

 

Now save the entries, and the system automatically creates a ledger group for the extension ledger in the background.

 

Define the Prediction Ledger

Before you can use the extension ledger in margin analysis, you need to define it as a prediction ledger by following the configuration path: Financial Accounting > Predictive Accounting > Define Prediction Ledger. Press F5 to assign the extension ledger EL as the prediction ledger, as shown below. Only if the extension ledger is created correctly will you be able to assign it as a prediction ledger for margin analysis. You can also define the extension ledger as Relevant for Availability Control, but this can only be activated for one extension ledger, not multiple.

 

Define the Prediction Ledger

 

Now that you have an extension ledger set up, you can use predictive accounting in margin analysis with SAP S/4HANA Finance.
