Mapping columns with BLOB format type in Microstrategy

Columns in the data source that use BLOB format types can be mapped to attribute forms and facts in MicroStrategy as the LongVarBin data type.

According to Microstrategy the data types such as Picture, BLOB, Text depending on data can be assigned as LongVarBin data type in the attribute definition.

LongVarBin

Picture, BLOB, Text depending on data

This data type is treated as a long string of binary data.

This representation in MicroStrategy has the following effects on including data from a BLOB format type on a MicroStrategy report or document:

•

Since the BLOB format type is represented as a LongVarBin, the data is displayed in either binary or hexadecimal representation. The data is not converted into any other format such as an image or PDF format. Therefore, columns in a data source that use BLOB format types to represent images, PDFs, or other non-binary or hexadecimal data should not be included in MicroStrategy.

•

MicroStrategy supports BLOB format types that include data records of up to 32 Kilobytes.

If a BLOB, that contains more than 32 Kilobytes, is included in a report, this can cause an error with a message such as String data, right truncated.

Below Information will be useful for further knowledge:

Different format types are compatible with different data types given the specific data in your column. Therefore, some of the data type-format type combinations below may not work with your specific data.

Data Type	Compatible Format Types
Big Decimal	Big Decimal
Binary	Number, Text, Picture
Char	Text, URL, E-mail, HTML Tag
Date	Date, Datetime
Decimal	Number
Double	Number
Float	Number
Integer	Number
LongVarBin	Picture, BLOB, Text depending on data
LongVarChar	Picture, Text
Numeric	Number
Real	Number
Time	Time, Datetime
Timestamp	Datetime, Date or Time depending on data
Unsigned	Number
VarBin	Picture, Text

Best practices for using Distribution Services in Microstrategy

Best practices for using Distribution Services MicroStrategy recommends the following best practices when scheduling Distribution Services subscriptions, in addition to the best practices given above: • For best results, follow the steps listed in High-level checklist to set up a report delivery system . • PDF, plain text, and CSV file formats generally offer the fastest delivery performance. Performance can vary, depending on items including your hardware, operating system, network connectivity, and so on. • The performance of the print delivery method depends on the speed of the printer. • When sending very large reports or documents: ▫ Enable the zipping feature for the subscription so that files are smaller. ▫ Use bulk export instead of the CSV file format. Details on bulk exporting are in the Reports chapter of the Advanced Reporting Guide . ▫ Schedule subscription deliveries to occur when your Intelligence Server is experiencing low ...

Derived metric based on attribute values

Derived metric based on attribute values Here is how could create and display data correctly on using below simple steps. Create a report with Category, Subcategory and Revenue. Create New Metric in a report or VI. Case((Category@ID = 1), Revenue, 0) Booksand Name it as Revenue for where 2 is Category ID for "Books" Report will display result as below. Result for new metric is blank. Now to fix this create a new Derived metric on Category attribute first with formula as Max(Category) {~ } and calling Books Now Edit the "Revenue for Books metric and Replace Category@ID with this new Books metric formula would looks like this Case((Books = 1), Revenue, 0). Report result would now display as expected as shown below

Prompt-in-prompt(Nested Prompts) in Microstrategy

Prompt-in-prompt(Nested Prompts) in Microstrategy Nested prompts allows you to create one prompt based on the other and other bases on another, nested prompts allows us to prompt the highest level(Like year) to middle level(like Quarter, then to the low level(like Month).

Types of prompts in Microstrategy

Types of prompts in Microstrategy The different types of prompts allow you to create a prompt for nearly every part of a report. Prompts can be used in many objects including reports, filters, metrics, and custom groups, but all prompts require user interaction when the report is executed. The correct prompt type to create depends on what report objects you want users to be able to base a filter on to filter data, as described in the list below. Filter definition prompts allow users to determine how the report's data is filtered, based on one of the following objects: Attributes in a hierarchy : Users can select prompt answers from one or more attribute elements from one or more attributes. The attribute elements that they select are used to filter data displayed on the report. This prompt lets you give users the largest number of attribute elements to choose from when they answer the prompt to define their filtering criteria. For example, on a repor...

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...
