Connection Mapping in Microstrategy

Connection Mapping in Microstrategy

A connection map in MicroStrategy is a link between a MicroStrategy user, a database connection, and a database login. 

It is used to apply database (row-level) security to a MicroStrategy user. Connection mapping allows administrators to assign a user or group in the MicroStrategy system to a specific login ID on the data warehouse RDBMS. The mappings are typically used to take advantage of one of several RDBMS data security techniques (security views, split fact tables by rows, split fact tables by columns) that architects may have already created. When a database connection map is modified, MicroStrategy Intelligence Server needs to be refreshed to recognize the changes.

Connection mapping is useful when MicroStrategy users must be differentiated from each other at the data warehouse level or when they must be directed to separate data warehouses. 

Below are the  two scenarios are described:.
  • Connecting to the data warehouse using different database logins:
    In this scenario, the project, database instance, and data warehouse are the same for the users in two groups, but the connection mapping specifies different database logins for each group. For example, the CEO of the company has a login that allows access to all data, while all other users have a login that allows limited access to data. In the diagram below, the two different logins used are "MSTR users" and "CEO".
     
  • Connecting to different data warehouses using the same project:
    In this scenario, the project, database instance, and database login are the same, but the connection mapping specifies different database connections (and therefore, different DSNs) for the two groups. In order for the project to work with both data warehouses, they must have the same structure. This is applicable in an environment where there are two data warehouses—for example, one with domestic data and another with foreign data—and users must be directed to one or the other based on the user group to which they belong when they log in to MicroStrategy. In the diagram below, the two different database connections used are "US " and "Europe". Although the data warehouse login ID for both the database connections is "MSTR users", within MicroStrategy the users belong to two different groups - 'US users' and 'Europe users'.

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...

Custom Subtotal Displays in MicroStrategy

Defining custom subtotal displays in MicroStrategy By default, when users apply subtotals in a report, the name of the subtotal is displayed in the subtotal line items that appear in the report. Users can use custom subtotals to give more control over the characteristics of a subtotal. Custom subtotals allow users to define custom subtotal line items that appear on the reports  U sers can make the subtotal name dynamic by typing special characters in the subtotal name field as listed in the following table. Character Description #A The name of the attribute under which the subtotal appears. #P The name of the attribute to the left of, or above the attribute under which the subtotal appears. #0 All the forms of the parent element. #1 The first form of the parent element reading from left to right or from top to bottom. #2 The second form of the parent element reading from left to right or from top to bottom. #3 The third form of th...

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...

Microstrategy Report Services documents and dashboards

Microstrategy Report Services documents vs Dashboards A MicroStrategy Report Services document displays data coming from multiple reports, with the data laid out and designed in presentation-quality format. Most data on a document is from one or more underlying datasets. A dataset is a standard MicroStrategy report. Other document components that do not originate from the dataset, such as static text used for a title or heading, page numbers, and images, are added by the document's designer and are stored in the document's definition. A Report Services (RS) dashboard is a special type of document. An RS dashboard is commonly only one page long, is intended to be viewed online, and usually provides interactive features that let analysts change how they view the dashboard’s data, as well as what data they are viewing. A broad selection of widgets and a wide variety of formatting options allow you to design a customized, interactive dashboard. Both documents and RS dashb...

System Manager workflow to execute on a schedule

Creating a System Manager workflow to execute on a schedule System Manager workflow can execute on a schedule or after an event has been triggered. This can be accomplished by creating a simple batch file, and scheduling that batch file to execute with a third-party tool like Microsoft Task Scheduler.   Note : To avoid user permission conflicts, the following steps must be performed with highest privileges.   In the below example, the workflow makes the i-server restarts every day.   1. The user must first have a valid workflow. This particular workflow is a template that is delivered out-of-the-box with System Manager.   2. Save the workflow in  .smw  format.   3. In a text editor (such as Notepad), enter the command line statement that the task scheduler should execute.     MASysMgr.exe -w C:\filename.smw” “UserName=User1 “Password=1234”   4. Save the file in  .bat  ...

Report filters are being ignored in Microstrategy report SQL

Report filters are being ignored in Microstrategy report SQL When users run a report using a simple filter, the filter is not applied to the report in MicroStrategy Developer 9.x and 10.x. The results returned to the users are not filtered as expected. The Report SQL indicates that the filter has not been applied. CAUSE: One scenario is that the MicroStrategy 10.x SQL Engine is ignoring the conditionality at the report level because a metric in the report also contains a related conditionality which has been set to "remove related report filter elements" or "ignore" the filtering criteria at the report level. ACTION: When a report contains the above situation, the follow steps can be done to have both filters applied and be merged for the report results to be executed with: If the report's and metric's filter affect attributes from the same hierarchy, check that the following setting is un-checked: This setting is placed in the me...

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...
