Update the data on an Intelligent Cube without having to republish the entire cube in MicroStrategy

Update the data on an Intelligent Cube without having to republish the entire cube in MicroStrategy



MicroStrategy has introduced a feature known as, Incremental Refresh Options, which allow Intelligent Cubes to be updated based on one or more attributes, by setting up incremental refresh settings to update the Intelligent Cube with only new data.

This can reduce the time and system resources necessary to update the Intelligent Cube periodically versus a full republish.
For example, if a user has an Intelligent Cube that contains weekly sales data, the user may want this Intelligent Cube to be updated at the end of every week with the sales data for that week. By setting up incremental refresh settings, he can make it so that only data for one week is added to the Intelligent Cube, without affecting the existing data and without having to reload all existing data.
Users can select two types of objects for the incremental fetch: a report or a filter.
  • Filter: The data returned by a filter is compared to the data that is already in the cube. By default, the filter defined for the Intelligent Cube is used as the filter for the incremental refresh.
  • Report: The results of a report are used to populate the Intelligent Cube. By default, the report template used is the same as the Intelligent Cube's template.
In order to set up an incremental refresh report, the user should first right click on the Intelligent Cube and select "Define Incremental Refresh Report":

This will bring up the Incremental Refresh Options editor:


Here, the user can define one of the following Refresh type options:
  • Update:  If new data is available, it is fetched and added to the Intelligent Cube, and if the data returned is already in the Intelligent Cube, it is updated where applicable.
  • Insert:  If new data is available, it is fetched and added to the Intelligent Cube. Data that was already in the Intelligent Cube is not altered.
  • Delete: The data that meets the filter or report's definition is deleted from the cube. For example, if the Intelligent Cube contains data for 2008, 2009 and 2010, and the filter or report returns data for 2009, all the data for 2009 is deleted from the cube.
  • Update only: If the data available is already in the Intelligent Cube, it is updated where applicable. No new data is added to the Intelligent Cube.
The type of object used for the incremental fetch can be selected in the Advanced tab:

Users simply have to run the incremental fetch report, and this will automatically refresh the data in the Intelligent Cube.

Case functions Microstrategy

Ca se functions Microstrategy Case functions return specified data in a SQL query based on the evaluation of user-defined conditions. In general, a user specifies a list of conditions and corresponding return values. Case This function evaluates multiple expressions until a condition is determined to be true, then returns a corresponding value. If all conditions are false, a default value is returned.  Case  can be used for categorizing data based on multiple conditions. This is a single-value function. Syntax Case ( Condition1 ,  ReturnValue1 ,  Condition2 , ReturnValue2 ,...,  DefaultValue ) Example Case(([Total Revenue] < 300000), 0, ([Total Revenue] < 600000), 1, 2) sum(Case (Day@DESC in (“Sat”,”Sun”), Sales, 0) {~+} Sum(Case(Category@DESC In("Books","Electronics"),Revenue,0)){~+} CaseV (case vector) CaseV  evaluates a single metric and returns different values according to the results.

Fact tables levels tables in Microstrategy explained

Fact tables levels in Microstrategy: Fact tables are used to store fact data. Fact tables should contain attribute Id's and fact values which are measurable. All the descriptive information about the fact tables should stored in Dimension tables either in Star Schema fashion or Snow Flake Schema fashion which is best suited to your reporting solution. Since attributes provide context for fact values, both fact columns and attribute ID columns are included in fact tables. Facts help to link indirectly related attributes using these attribute ID columns. The attribute ID columns included in a fact table represent the level at which the facts in that table are stored. So the level of a fact table in the Fact_Item_Day_Customer can be the attribute Id's which is at Day, Item & Customer Id level. For example, fact tables containing sales and inventory data look like the tables shown in the following diagram: Base fact columns ver...
