In earlier versions of Designer, the objects with hints did not parse In Designer XI Release 2, the object will parse if you have entered the hint correctly
Generate QR-Code In Visual Studio .NET

Draw QR Code ISO/IEC18004 In Visual Basic .NET
Using Barcode creation for .NET framework Control to generate, create QR Code ISO/IEC18004 image in Visual Studio .NET applications.
Reusing Interactive Objects with @Variable
Code 128 Drawer In Java
Using Barcode printer for Java Control to generate, create Code 128 image in Java applications.
Creating GTIN - 13 In Java
Using Barcode generator for Java Control to generate, create EAN 13 image in Java applications.
Designer allows you to reuse the prompt as a variable that you can then use in other objects The variable can be one that you create with @Prompt, or it can be a system variable BusinessObjects XI provides the following system variables: BOUSER The BusinessObjects Enterprise user ID BOPASS The BusinessObjects Enterprise password DBUSER The database credentials used to connect to the data source DBPASS The database password used to connect to the data source As an example, let s assume that a hierarchical PRODUCT table contains both products and employees responsible for those products So that users automatically see information for their products, the My Product object could contain the following WHERE clause:
Creating Bar Code In Java

Paint EAN 13 In Java
Using Barcode generator for Java Control to generate, create EAN-13 image in Java applications.
PRODUCTPRODUCT_OWNER = @Variable('BOUSER')
Draw Leitcode In Java
Using Barcode drawer for Java Control to generate, create Leitcode image in Java applications.

Reusing Interactive Objects with @Where
Generating UPC-A Supplement 2 In Objective-C
Using Barcode generation for iPhone Control to generate, create UPCA image in iPhone applications.
ECC200 Generation In .NET Framework
Using Barcode printer for VS .NET Control to generate, create Data Matrix image in .NET framework applications.
As mentioned previously, @Where allows you to reuse a WHERE clause in multiple objects There are two benefits to using @Where: the first is decreased maintenance, and the second is decreased user prompting If a query contains multiple occurrences of the exact same prompt, Web Intelligence and Desktop Intelligence will prompt the user only one time For example, let s assume that users must filter Customer information by City to ensure only a limited amount of data is returned The dimension object City contains a prompt A designer could add @Where (Customer\City) to Customer Name, Customer Id, Customer Age Group
Draw UCC - 12 In .NET Framework
Using Barcode printer for Reporting Service Control to generate, create UPC-A Supplement 5 image in Reporting Service applications.
EAN13 Decoder In VB.NET
Using Barcode reader for Visual Studio .NET Control to read, scan read, scan image in VS .NET applications.
Part II:

Using Barcode recognizer for Java Control to read, scan read, scan image in Java applications.
Make ECC200 In None
Using Barcode generator for Office Excel Control to generate, create Data Matrix image in Excel applications.
A Better Universe
Even if a query contains all four of these objects in a query, the user is prompted only once to select a city
Prompts in Objects vs Reports
Objects with prompts achieve a similar functionality as queries with prompts ( 20, Prompts ) In 14, you will look at the pros and cons of where to put this kind of intelligence The main difference to consider with prompts is flexibility and maintenance If you want to give the users flexibility, put the prompts in the query If you want to minimize your maintenance costs, keep the prompts centralized in the universe objects The following table summarizes some of the key differences between prompts in objects versus prompts in a query
Universe Object with Prompt Designer builds into universe Centralized, so cost-effective to maintain because the designer creates the prompt once Users cannot remove, so it can be inflexible, but error-proof, as it requires an answer Query with Prompt User builds in query Decentralized, so expensive to maintain because users must create the prompt in every document Users can remove, providing flexibility
Aggregate Awareness
An aggregate table is a summary table that DBAs build to execute queries faster Aggregate tables are smaller than detail tables and can be aggregated in a number of ways Most DBAs will strive for a certain compression ratio for example, 10:1; the aggregate or summary table should be ten times smaller than the detail table, or for every ten detail rows, there is one summary row Before you spend your time reading this section, talk to your DBA to determine if your database will automatically take advantage of aggregate tables Newer versions of databases can automatically rewrite a query to leverage an aggregate table when it is available The universe designer does not need to explicitly specify these aggregates Unfortunately, though, it seems many organizations have been slow to take advantage of the database s query rewrite, so I am providing instructions here on how to use Designer s aggregate awareness Given the choice, though, don t do this in the universe as it poses maintenance challenges; do it in the database Alternatively, consider third-party solutions from technology partners such as HyperRoll or Netezza that are geared to improving query performance Figure 11-3 shows two sample dimensions, Time and Product In the Time dimension, there are five years of history, with four levels going from Year to Day Within a given year, there are 365 days If the Time dimension contains five years of history, this results in 1825 rows of data The Product dimension has four levels, ranging from Total Product to individual SKU There are 210 SKUs (this is a very small product dimension) A DBA may create an aggregate table summarizing data to any of these levels, across any dimension, as shown in Figure 11-4 The SALES_FACT_DAY table contains daily sales figures for five years, at the SKU level for all customers The SALES_FACT_MONTH table aggregates sales by month and by product line Customer is not aggregated in any way The following table shows the potential number of rows in such a fact table, if you have 30,000 customers Typically, not every product sells daily, nor does every customer buy every product on a daily basis, so the potential rows represent strictly a worst-case scenario
