If there is a cube with uncompressed requests and 10 dimensions (every dimension brings with it a local bitmap index) than there are. step-by-step process to create Re-Partitioning of Info Cube in SAP-BI.

You use partitioning to.
When the number of partitions is low, the user partiitioning not experience trouble from this direction at the beginning. Transformation created for this SPO: If there is a cube with uncompressed requests and 10 dimensions every dimension brings with it a local bitmap index than there are partitions for the table itself and 10 x index partitions which makes a total of The aggregates do not get adapted automatically but the next time you rebuild them or they get rebuild by a changerun they will reflect the new partitioning as well.
This is indeed helpful for BW Developer to start thinking about partitioning that helps improve report performance.

Database tables of InfoCubes often contain several million records, so database operations of any nature are time-consuming for these tables. And since the E table partitioning is handed over to all aggregates at least to those that contain the corresponding partitioning time characteristicthe amount of lartitioning due to E facttables must be multiplied by the number of aggregates over that cube and may in total sum up substantially in certain scenarios.
A t tachments 0 Page History. December 2, at 6: The partition can be created only if a partitjoning characteristic is present as the key of the DSO.

Partitions enable the parallel processing of the queries. Records 2 and 3 are not consistent: June 23, at 8: You use partitioning to split the total dataset for an InfoProvider into several, smaller, physically independent and redundancy-free units.
Repartitioning can be useful if you have already loaded data to your InfoCube and you have loaded more data into your InfoCube than you had planned when you partitioned it, you did not choose a long enough period of time for partitioning or some partitions contain no data or little data due to data archiving over a period of time. Hope they will be helpful too.
The role of the data partitioning comes to fore here. Resulting from the value range: Additionally there is lots of DB cost for returning the allocated disk space. See here which we have same cocnepts.
