Logical Views to specify an outer join between two attribute lookup tables when only attributes are on a report

Apart from using the VLDB properties to create the left outer join, article describes how to use the Logical View to specify an outer join between two attribute lookup tables when only attributes are on a report. This method exists as attribute only outer joins will not be generated on their own by the MicroStrategy SQL engine. This is because they are only necessary with ragged/unbalanced hierarchies which are not supported as null attribute IDs are not supported (parent elements with no child elements or child elements with no parents).

Brief instructions are provided using the example below.

Consider, two attributes: Parent01 and Child01 have a parent-child relationship. Their Lookup tables are defined, as follows

Parent01	Child01

Note that although there are 4 ID values for the attribute Parent01, there is no defined relationship for the Parent01 element p4 (ID=4) in the Lookup table for attribute Child01. Placing both attributes on a report will result in the following SQL and data returned. Parent01's element p4 will not be returned. This is known as a ragged hierarchy and is not supported in MicroStrategy.

SQL	Data Returned
select a12.parent01_ID parent01_ID, a13.parent01_DESC parent01_DESC, a12.child01_ID child01_ID, a12.child01_ID child01_ID0 from child01 a12 join parent01 a13 on (a12.parent01_ID = a13.parent01_ID)

To overcome this issue, create a Logical View with the following SQL. Note the Left Outer Join.

SQL	Logical View Definition
select a12.parent01_ID parent01_ID, a12.parent01_DESC parent01_DESC, a11.child01_ID child01_ID, a11.child01_DESC child01_DESC from parent01 a12 left outer join child01 a11 on (a11.parent01_ID = a12.parent01_ID)

Modify the attribute Child01 to include the new Logical View as a source table and redefine a relationship to attribute Parent01 using the new Logical View.

Add Source Table	Add Relationship

Executing the same report will now return all elements for Attribute Parent01.

SQL	Data Returned
select /* RRR01 / a12.parent01_ID parent01_ID, a12.child01_ID child01_ID from (select a12.parent01_ID parent01_ID, a12.parent01_DESC parent01_DESC, a11.child01_ID child01_ID, a11.child01_DESC child01_DESC from parent01 a12 left outer join* child01 a11 on (a11.parent01_ID = a12.parent01_ID)) a12

Relative path for images in Microstartegy

Best practices on how to reference an image specified using a relative path for exported documents in MicroStrategy If possible, users should use HTTP paths to reference an image other than relative path or absolute path. If it is necessary to use a relative path to reference image, multiple locations need to store the copy of image as shown in the following table: Important notes: MicroStrategy Web Server is not involved in storing image when exporting. Image should be stored in Intelligence Server or MicroStrategy Developer Client For MicroStrategy Developer export, local MicroStrategy Developer handles the export, image should be placed on every single Developer machine If you don't know your Common Path or MSTR Home Path you can obtain them from the following registry keys if using windows or msireg.reg if using Unix HKEY_LOCAL_MACHINE --> SOFTWARE -->Microstrategy --> DSS Server -> Casetor -->Home Path HKEY_LOCAL_MACHINE --> SO...

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...

Disable data blending in MicroStrategy

Disable data blending in MicroStrategy Starting in MicroStrategy 9.4 data blending was made available for documents and dashboards. This permits grid, graph and widget objects to source data from multiple different datasets at the same time. This is available under the analytical engine VLDB properties inside of project configuration. The property is named "document grids from multiple datasets" and defaults to enabled but can be set to disabled. Below are the steps to enable/disable the settings of data blending: 1. Go to project configuration by right clicking on specific project(You need admin rights to do this). 2. In the Project configuration windows as shown below select Configure under Project level VLDB settings section. 3. Now it will open the VLDB settings window, select + on " Analytical Engine Settings " and then click on " Document Grids from multiple datasets " option. You will be presented with two...

Create an alert-based subscription in MicroStrategy Distribution Services

Create an alert-based subscription in MicroStrategy Distribution Services on Web Subscription to a report or Report Services document which will be executed when a certain conditional threshold is met based on another executing report. For example, a scheduled report executes which shows the Revenue by day for the past week. If the Revenue on any one day falls below a certain value, a subscription to another report or Report Services document can be triggered and delivered to a recipient. An alert based subscription can only be created directly on a report; however, another report or Report Services document can be delivered when the alert based subscription is triggered. Note: you need a grid report to create an alert and you cannot create if you want to create on a document with text boxes. The following example will walk through the basic steps on how to setup a subscription based on an alert like this: Follow the brief steps bel...
