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. It can be used to perfo...

Control the display of null and zero metric values

Show   Control the display of null and zero metric values in a grid report You can determine how to display or hide rows and columns in a grid report that consist only of null or zero metric values. You can have MicroStrategy hide the rows and columns in the following ways: Hide rows and columns that consist only of null metric values Hide rows and columns that consist only of zero metric values Hide rows and columns that consist only of null or zero metric values (default) Once you have defined how MicroStrategy hides null and zero metric values in the grid, you can quickly show or hide the grid using the Hide Nulls/Zeros option in the Data menu, as described below, or by clicking the  Hide Nulls/Zeros  icon  in the Data toolbar. To determine how null and zero metric values are displayed or hidden in a grid report Open the report in Edit mode. From the  Tools  menu, select  Report Options . The Report Options...

Settings for Outer Join between metrics in MicroStrategy

Settings for Outer Join between metrics in MicroStrategy MicroStrategy adopts multi-pass logic to determine the execution plan for a report. This means that every metric is evaluated in separate SQL passes. Outer Joins come into play when MicroStrategy Engine merges the results from all SQL passes into one report. For a multi-pass report, different Outer Join behaviors can give the user completely different results. In addition, report metrics can be of different types which can, in some cases, influence the result of the outer join. In MicroStrategy, there are two settings that users can access to control Outer Join behavior : Formula Join Type and Metric Join Type . Metric Join Type: VLDB Setting at Database Instance Level Report and Template Levels Report Editor > Data > Report Data Options Metric Level   Metric editor > Tools > Metric Join Type Control Join between Metrics Formula Join Type: Only at Compound/Split...

Microstrategy Dashboard performance improvements steps

Microstrategy  Dashboard performance improvements steps: Many times, causes of poor performance can be simplified to specific components. To troubleshoot performance issues, users must identify these components, then make the appropriate modifications to the environment and/or to the MicroStrategy dashboard to reduce bottlenecks. Dashboard execution stages can be represented below: MicroStrategy Intelligence Server When an end user makes a  Document Execution Request  through any client (a web browser via MicroStrategy Web, the MicroStrategy Desktop/Developer client, the MicroStrategy Mobile app, or the MicroStrategy Office client), the request is sent to the MicroStrategy Intelligence Server, which processes the request and prepares the response. The MicroStrategy Intelligence Server will execute all children datasets on the dashboard by either generating SQL and running this against the data warehouse, or by fetching data from a cache. The Inte...

Microstrategy Dossiers explained

Microstrategy  Dossiers With the release of MicroStrategy 10.9, we’ve taken a leap forward in our dashboarding capabilities by simplifying the user experience, adding storytelling, and collaboration.MSTR has  evolved dashboards to the point that they are more than dashboards - they are  interactive, collaborative analytic stories . Ultimately, it was time to go beyond dashboards, both in concept and in name, and so  the've  renamed VI dashboards to  ‘ dossiers ’.  Dossiers can be created by using the new Desktop product or Workstation or simply from the Web interface which replaces Visual Insights. All the existing visual Insights dashboards will be converted to Dossiers   With MicroStrategy 10.9, there was an active focus on making it easier to build dashboards for the widest audience of end users. To achieve this, some key new capabilities were added that make it easier to author, read, interact and collaborate on dashboards ...

Star schemas and aggregate (or summary) fact tables Aggregate tables can further improve query performance by reducing the number of rows over which higher-level metrics must be aggregated.  However, the use of aggregate tables with dimension tables is not a valid physical modeling strategy. Whenever aggregation is performed over fact data, it is a general requirement that tables joined to the fact table must be at the same attribute level or at a higher level. If the auxiliary table is at a lower level, fact rows will be replicated prior to aggregation and this will result in inflated metric values (also known as "multiple counting"). With the above Time dimension table, a fact table at the level of Day functions correctly because there is exactly one row in DIM_TIME for each day. To aggregate the facts to the level of Quarter, it is valid to join the fact table to the dimension table and group by the quarter ID from the dimension table. Sql select DT...
