Execution of Consolidation with the Consolidation Monitor 
Purpose
Consolidation in SEM Business Consolidation is designed for various consolidation purposes. This depends on how you set up your data model and how you use the consolidation tasks.
Prerequisites
The consolidation units must report their financial data so that it can be collected in the Consolidation system.
Note the following important prerequisites needed for error-free data collection.
Subassignments
The Consolidation system needs account assignments, such as partner units, transaction types, transaction currencies, etc., in order to perform the consolidation tasks. For example, automated elimination of IU revenue and expense is only possible if the system knows which partner units caused the revenues and expenses.
In FS item customizing, you define which subassignments each item requires. These subassignments must be included in the reported financial data.
Creating an Initial Data Set
When implementing the SAP Consolidation component, legacy data concerning your consolidation units usually already exists.
There is basically no difference between transferring legacy data and transferring the data of the current period. When collecting data in SAP Consolidation for the first time, you enter the cumulative value for the historical data.
Process Flow
A. Customizing
You define your Customizing settings to meet your specific requirements in the
Workbench of SAP Consolidation.The standard SAP system includes default settings for many consolidation methods. Check each method and decide whether you want to use the default settings as the are, or tailor them accordingly. There are copy functions to assist you.
B. Execution of the Consolidation Tasks
There are tasks:
You execute all of these tasks in the
Consolidation Monitor.The following graphic shows a summary of the order of the tasks in the consolidation monitor:

This task is only needed if prior year data already exists in the totals database.
The system writes the reported financial data to the InfoCube for the totals data.
This task is not required (in contrast to the validation of standardized financial data in group currency).

Nevertheless, to ensure that the reported financial data is consistent, we recommend using the validation of reported data at this point, if no consistency check has yet taken place in some other fashion.

An alternative is to also execute this task after currency translation.
This is usually the currency of the parent company when company consolidation is involved.

The consolidated financial statements of a corporate group often need to disclose the retained earnings of the parent unit within the group.
You can use reclassifications to reclassify the retained earnings of subsidiaries as appropriations.
Result
You can generate SAP BW reports on the consolidated data. You can also transfer the data to other SEM components, such as Business Planning and Simulation (SEM-BPS).
