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.

N-Level deep nested prompts in MicroStrategy

N-Level deep nested prompts in MicroStrategy Prompt-in-prompt is a feature in which the answer to one prompt is used to define another prompt. This feature is only implemented for element list prompts. The following procedure describes how to achieve this: Create the highest level filter. This is a filter which contains a prompt on an attribute element list. Create a filter on the attribute "Year." Click "prompt on attribute element list" and click "Next" through the rest of the screens to accept the default values. Do not set any additional conditions. Save the filter as "YEAR FILTER:"   From this level on, each filter will contain both a prompt on an element list and will have its element list filtered by the filter created one level above it. There is no limit to the number of such filters that can be layered. Create a filter on attribute "Quarter" and click "Prompt." Select "Use a filter to reduce the nu...

Split Hierarchy with M-M(many to many) relationships in Microstrategy:

Split Hierarchy with M-M(many to many) relationships in Microstrategy: Split Hierarchy with M-M relationships: Explanation A split hierarchy is one - that at the lowest level - has more than one child. The schema looks like the following diagram. Problem Reports that contain B or C will ignore filters on the other . Recommendation MicroStrategy recommends to have only one child at the lowest level. Workaround / Solution Make B and C parents of a new compound attribute using both columns as its ID with A B and C as its parents.

"System Prompt" and its uses in MicroStrategy

System Prompt and its uses in MicroStrategy WHAT IS A "SYSTEM PROMPT"? "System Prompt" is a system object that was introduced back in version 8.0.0. The object is named as "User Login" and is implemented as a prompt object. The object can be found under Public Objects > Prompts > System prompts, as shown below: Unlike ordinary prompt objects, system prompts don't require any answers from the user. When a report containing a system prompt runs, the prompt is answered automatically with the login of the user who runs the report. On the other hand, like other prompt objects, answers to system prompts are used to match caches. Therefore, users don't share caches for reports that contain system prompts. For details on how caches are matched, refer to the following MicroStrategy Knowledge Base document: KB5300-7X0-0147 - How are caches matched in MicroStrategy Intelligence Server 7.x? WHEN ARE SYSTEM PROMPTS USED?    System pr...

Partition Key Selection guidelines in MicroStrategy

Partition Key Selection guidelines MicroStrategy The partition attribute is typically dictated by specific application needs. Below are some general guidelines for identifying a good partition attribute. Some of the largest fact tables in the application are typically good candidates for partitioning and thus influence the choice of the partition attribute.  Data should be partitioned in such a way that it allows for the most number of partitions to be involved in any question that is asked of the application. Attributes that are frequently used for filtering or selections do not make for good partition attributes. The partition attribute should allow for near uniform distribution of data across the partitions, so that the workload on each partition is evenly distributed. To support best dashboard execution and concurrency performance, MicroStrategy has chosen to limit the number of logical CPUs engaged for any single grid evaluation to  4 . Columns on which some of the larger...
