DataStore Objects for Direct Update 

Definition

The DataStore object for direct update differs from the standard DataStore object in how the data is processed. In a standard DataStore object, data is stored in different versions (active, delta, modified), whereas a DataStore object for direct update contains the data in a single version. Therefore, data is stored in precisely the same form in which it was written to the DataStore object for direct update by the application. In the BI system, you can use a DataStore object for direct update as a data target for an analysis process. For more information, see Analysis Process Designer.

The DataStore object for direct update is also required by diverse applications, such as SAP Strategic Enterprise Management (SEM) for example, as well as other external applications.

Use

DataStore objects for direct update ensure that the data is available quickly. The data from this kind of DataStore object is accessed transactionally, that is, data is written to the DataStore object (possibly by several users at the same time) and reread as soon as possible.

It offers no replacement for the standard DataStore object. Instead, an additional function displays those that can be used for special applications.

Structure

The DataStore object for direct update only comprises a table for active data. It retrieves its data from external systems via fill- or delete- APIs. See to DataStore Data and External Applications.

The load process is not supported by the BI system. The advantage to the way it is structured is that data is easy to access. They are made available for reporting immediately after being loaded.

Creating DataStore Objects for Direct Update

When creating a DataStore object, you can change the DataStore object type under Settings via the context menu. The default setting is Standard. The switching of DataStore object types between standard and direct update is only possible if no data exists yet in the DataStore object.

Integration

Since DataStore objects for direct update cannot be filled with BI data using staging (data is not supplied from the DataSources), they are not displayed in the scheduler or in the monitor. However, you can update the data of DataStore objects of this type to additional InfoProviders.

If you switch a standard DataStore object, that already has update rules, to direct update, the update rules are set as inactive and can no longer be processed.

Since no change log is generated, delta update of InfoProviders stored at the end of the process is not possible.

The DataStore object for direct update is available as an InfoProvider in the BEx Query Designer and can be used in reporting.
