In the following example, only record 1 is consistent.
Features When you activate the InfoProvider, the system creates the table on the database with one of the number of partitions corresponding to the value range. No search term specified.

For such cases, the partitioning of an InfoCube tables is a very effective option to improve performance. Partitioning on an Infocube’s F-facttable 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 Summary In BW 3.
Note that you can only change the value range when the InfoProvider does not contain data. This means that you should not create partitions that are too large or too small. Hence include either of these time characteristic in the InfoCube to be partitioned under the Time dimension as per the business requirement.
Let us suppose that the time characteristic used is 0Calmonth and the range of month given is The partitions are accessed simultaneously during the query processing and then the result is consolidated to provide the final output.

infoube Open link in a new tab. But it will run into problems randomly at first, when the number of partitions increase, and permanently, after the number of partitions have exceeded some not specifiable, system and context dependent threshold. InfoCube partitioning is done at database level and can be based on one of the following date based info objects:.
This will cause unacceptable query response times if there are too many partitions.
BW, by its virtue has to handle psrtitioning huge amount of data. And at some point compression is not possible in a reasonable amount of time anymore, because deleting a partition takes so long that partiitioning whole workflow on that cube and others later up the chain is not fitting into the allocated timeframes. When the read access to the partitioning characteristic is limited, a number of partitions may be possibly excluded from the read process, so the data base will be smaller and comprehensive data will be found and read significantly faster.
Thnx a lot Parimi. The aggregates do infocub 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.

Clicking on OK leads to the following screen: SPO based on cube: July 8, at 9: August 27, at 8: But always check on google before making doc. Transformation created for this SPO: Partitioning is an activity that happens at the database level logical partitioning is not discussed here and with 7.
This fact adds to the problems and the point in time you will partitiojing them. In situations with a high load frequency it will most certainly run into problems in this area sooner or later. Two extra partitions are created to accommodate the data which is less than the time selection given and the data which lies beyond the given time selection.
