What is the use of InfoCube in SAP BW?
SAP BW InfoCube is a type of InfoProvider on which queries can be defined or executed. SAP BW InfoCubes can physically store the data in real database tables or they can just virtually collect the data without storing it permanently.
What is BW compression?
During the compression BW moves data from the normal F-table to the compressed E-Table. By choice the compression can be all or only part of the requests that have been loaded. The OLAP processor is automatically combining the E and F table during the query.
What are InfoCube aggregates?
An aggregate is a materialized, aggregated view of the data in an InfoCube. In an aggregate, the dataset of an InfoCube is saved redundantly and persistently in a consolidated form on the database. Aggregates allow quick access to InfoCube data during reporting.
What is roll up aggregates SAP BW?
When you load new data packages (requests) into the InfoCube, these are not immediately available in reporting for use in an aggregate. In order to supply the aggregate with the new InfoCube data, you first have to load these into the aggregate tables for a set time frame. This process is known as roll up.
How do I do a compression in InfoCube?
When you load data into the InfoCube, entire requests can be added all at once. Each of these requests has its own request ID, which is included in the fact table in the package dimension. This makes it possible to pay particular attention to individual requests.
What is roll up in InfoCube?
What is aggregate in SAP BW?

What is rollup and compression in SAP BW?
Rollup is used to load the newly added data to the aggregate cube. Compression: Used to compress N number of requests into single request. whats the advantage of this is, it increase your disk space.
What is the meaning of InfoCube?
an InfoCube is a multidimensional data structure and a set of relational tables that contain InfoObjects. 2. INFOCUBE- STRUCTUREStructure of InfoCube is considered as ESS-Extended Star Schema/Snow Flake Schema, that contains. • 1 Fact Table. • n Dimension Tables.
What is E table and F table?
The data in the E fact table is compressed and occupies lesser space than F fact table. When you load a data target, say a cube, the data is stored in the F fact table. If the cube is compressed, the data in the F fact table is transferred to the E fact table.
How can I delete compressed data from the infocube?
This function is critical, since you cannot delete compressed data from the InfoCube using its request ID. You must be absolutely certain that the data loaded into the InfoCube is correct. You can choose request IDs and set them for compression. You can schedule the function immediately or in the background.
What are the restrictions for infocubes in SAP notes?
For information about further restrictions, see SAP Notes 1587759 and 1224631 . For non-cumulative InfoCubes, you can ensure that the non-cumulative marker is not updated by setting the No Marker Updating flag.
When should i compress a Delta request?
In order to obtain satisfactory performance, you should compress subsequent delta requests. In order to obtain satisfactory performance and to save space on the memory, compress a request as soon as you have established that it is correct and should not be removed from the InfoCube.
Is it possible to run zero-elimination for infocubes with aggregate key figures?
Zero-elimination is only allowed for InfoCubes where all key figures have aggregation behavior ‘SUM’. You cannot run zero-elimination for non-cumulative key figures. For information about further restrictions, see SAP Notes 1587759 and 1224631 .
