Data Stream 
Use
With the help of the definition of the data stream and with the help of other Customizing settings, the system calculates how it should update the operational data streams in the consolidation processing ledger.
Features
The following graphic shows an overview of how the system calculates the Consolidation data streams with the realtime update of operational documents.
Subsequently
you will find explanations for the data stream with the utilization of the rollup or the periodic extract.

View, version and Consolidation chart of accounts.
From the IMG settings Define Data Streams (section Preparations in the Consolidation system) the system calculates the active data streams per active consolidation type).
According to the data transfer method the following applies:
- The realtime update can fill several data streams parallel, that means several data streams can be active at the same time for an active consolidation type.
- A rollup can only fill one data stream. When several data streams are active for an active consolidation type, then the system must choose a data stream exactly.
- When you start posting the rollup data in the Consolidation menu via the data monitor, then the system chooses view, version and consolidation chart of accounts from the global parameters.
- When you start posting the rollup data in the Consolidation menu via the detail monitor, then the system identifies the view, version and consolidation chart of accounts from the entries which you made while defining the rollup in the rollup reset set.
- The periodic extract can only fill one data stream. You choose this data stream by entering the view, version and consolidation chart of accounts while applying the extract on the initial screen.
- Consolidation processing ledger
- The system calculates the Consolidation processing ledger(s) from the master data of the consolidation unit on the realtime update.

The system updates the operational document in every assigned ledger, provided that the following conditions are filled:
- The ledger must be assigned all consolidation units which are to be posted to via the document.
- The consolidation units must use the same fiscal year variant.
- On rollup the system calculates the Consolidation processing ledger(s) which you have entered in the rollup sequence while defining the rollup. Make sure that these ledgers are assigned to the consolidation units to be posted to.
- While applying the periodic extract in Consolidation, the system calculates the ledger from the global parameters. Make sure that this ledger is assigned to the consolidation units to be posted to.
From the posting date and the fiscal year variant, which are set in the master data of the consolidation unit, determines the system the fiscal year and the period.
When creating a rollup, the system uses the fiscal year variant for consolidation which you specified in the IMG setting Activate Data Transfers (section Preparations in the Sender System). If the company code data for the rollup is kept in the sender ledger under a different fiscal year variant, the system converts the periods in the rollup.
The systems determines the fiscal year and period from the global parameters.

- Consolidation unit and consolidation group
On the basis of the IMG settings Enterprise Structure and Define Concatenation Rules, the system converts the operational organizational units into the organizational units of Consolidation.
- With realtime update and rollup
From the IMG settings Assign Chart of Accounts to the Cons Chart of Accounts (section Preparations in the consolidation system) and the IMG settings Operational Accounts: Groups Account Assignment.
The periodic extract already delivers the data with the consolidation item identification, as the extract is generated with the group’s financial statement version.
The system reads the account assignment category from the master data of the FS item and calculates the breakdown by subassignments.
- When the account assignment category plans a breakdown by subitems, then the system calculates the sender field from the subitem category and transfers the characteristic value of the sender field into the subitem.
- When the account assignment category plans a breakdown by partners , the system converts the partner assignment in the operational document into the partner unit (analogue to the conversion of the consolidation units).
- When the account assignment category plans a breakdown by custom subassignments, then you have to set up the transmission of operational characteristics in these subassignments in the IMG settings Preparation and Activation of the Data Transfer.
