SAP BI IDT Information Design Tool 4 Creating Bus: A Detailed Guide to Building Business

Layers

sap bi idt information design tool 4 creating bus is a fundamental topic for anyone

diving deep into SAP BusinessObjects Universe Design. The Information Design Tool (IDT)

is an essential utility within SAP BI that enables developers and data architects to create

semantic layers known as Universes. These universes act as an abstraction layer between

complex data sources and end-users, ensuring that business analysts can easily generate

reports without needing to understand the underlying database intricacies.

One of the key steps in universe design using SAP BI IDT is creating Business Layers

(often abbreviated as BUS). This process organizes and models the business logic in a way

that is intuitive and accessible for reporting. In this article, we will explore the ins and outs

of using SAP BI IDT for creating business layers, discuss best practices, and share insights

that will empower you to build efficient, scalable universes.

Understanding SAP BI IDT and Its Role in Universe Design

Before we jump into creating business layers, it’s important to understand what SAP BI

IDT stands for and its role in the SAP BusinessObjects ecosystem. The Information Design

Tool is the successor to the Universe Design Tool (UDT) and offers enhanced capabilities

for creating and managing relational universes. These universes connect to multiple data

sources, including relational databases, OLAP cubes, and web services.

The IDT separates the universe into three distinct layers:

Data Foundation Layer: Defines tables, joins, and the physical structure of the

1.

data.

Business Layer (BUS): Contains objects such as dimensions, measures, and filters

2.

that represent business concepts.

Connection Layer: Manages the database connections and credentials.

3.

The business layer is where the real magic happens because it translates technical data

into meaningful business terms, making it easier for users to create queries and reports.

What is a Business Layer in SAP BI IDT?

The business layer, sometimes called the semantic layer, is a logical grouping of objects

that represent the business view of data. It is designed to hide the complexity of the

underlying database schema and present information in a way that aligns with business

terminology and reporting needs.

In SAP BI IDT, creating a business layer involves defining objects such as:

Dimensions: Attributes or descriptive data points (e.g., Customer Name, Product

1.

Category).

Measures: Numeric data that can be aggregated (e.g., Sales Amount, Quantity

2.

Sold).

Filters: Predefined conditions to restrict data (e.g., Date ranges, Region).

3.

These objects can be organized into folders and hierarchies to improve user navigation

and query building.

Why Creating Business Layers is Crucial

Creating an effective business layer ensures that end users can interact with data

intuitively without needing to understand SQL syntax or database relationships. A well-

structured business layer also improves query performance, reduces errors, and promotes

consistency across reports.

When you design a business layer correctly in SAP BI IDT, you empower business analysts

to:

Build meaningful reports quickly.

1.

Use familiar business terms rather than technical jargon.

2.

Ensure data accuracy and integrity.

3.

Maintain flexibility to adapt to changing business requirements.

4.

Step-by-Step Guide: Creating Business Layers in SAP BI IDT

Now that we grasp the importance of business layers, let’s walk through the process of

creating one using SAP BI IDT.

1. Launch the Information Design Tool and Open Your Project

Start by opening IDT and loading your existing project or creating a new one. Ensure that

you have already set up a Data Foundation Layer connecting to your data sources. The

Data Foundation Layer defines tables and joins, which form the backbone of your business

layer.

2. Add a New Business Layer

Right-click on the project or the Data Foundation Layer and select New Business Layer.

Assign a meaningful name reflecting the business domain, such as "Sales Business Layer"

or "Customer Insights."

3. Define Business Objects

With the business layer open, begin creating objects:

Create Dimensions: Click the New Object button and select Dimension. Choose

1.

the relevant columns from the data foundation and assign friendly names.

Create Measures: Similarly, add measures by selecting numeric columns and

2.

specifying aggregation types like SUM, AVG, COUNT, etc.

Add Filters: Define filters to help users narrow down data automatically when

3.

running reports.

4. Organize Objects into Folders and Hierarchies

To improve usability, group related objects into folders such as "Customer," "Product,"

"Time," and "Financials." You can also create hierarchies (e.g., Year > Quarter > Month) to

enable drill-down capabilities in reports.

5. Define Object Properties and SQL Expressions

Each business object can have associated properties and SQL expressions. You can

customize SQL to handle complex calculations or data transformations. For example,

defining a calculated measure for Gross Profit or a conditional attribute using CASE

statements.

6. Validate and Test the Business Layer

Before deploying, validate your business layer for syntax errors or broken links. Use the

query panel in IDT to create test queries and ensure data retrieval aligns with

expectations.

Best Practices for Creating Business Layers in SAP BI IDT

As you work on building business layers, keep these tips in mind to create robust and

maintainable universes:

Use Descriptive and Consistent Naming Conventions: This makes it easier for

1.

users to understand and find the objects they need.

Limit the Number of Objects: Avoid clutter by only including relevant objects; too

2.

many options can confuse users.

Leverage Hierarchies: Organize data logically to support drill-down and

3.

aggregation in reports.

Document Your Design: Maintain notes and metadata within the universe to help

4.

future developers or analysts.

Optimize SQL Expressions: Ensure that complex calculations are efficient to

5.

prevent performance issues.

Regularly Update and Maintain: Business requirements evolve, so keep your

6.

business layer up to date with changing data models.

Common Challenges When Creating Business Layers and How to

Overcome Them

While SAP BI IDT provides a powerful platform for universe design, creating business

layers can come with hurdles. Understanding common pitfalls helps you avoid them.

Handling Complex Data Models

Sometimes, underlying databases have complex schemas with many-to-many

relationships or circular joins. Simplify your data foundation layer to avoid confusion, and

use aliases or contexts within IDT to manage these complexities.

Performance Issues

If queries run slow, review your SQL expressions and indexes on the database side. Using

aggregated tables or materialized views can improve performance dramatically.

Ensuring Data Security

Business layers should respect data security policies. Utilize object-level or row-level

security features in IDT to restrict data access based on user roles.

Maintaining Consistency Across Universes

In large organizations, multiple universes may exist. Establish governance processes and

standardize business objects to ensure consistency and reduce duplication of effort.

Leveraging Advanced Features in SAP BI IDT for Business Layers

Beyond basic object creation, SAP BI IDT offers advanced capabilities to enhance your

business layers further.

Parameters and Prompts: Create dynamic universes where users can input

1.

values at runtime, making reports more flexible.

Derived Tables: Use SQL queries within the universe to create virtual tables for

2.

calculated or filtered data.

Linked Universes: Combine multiple universes to offer broader data perspectives.

3.

Support for Multiple Data Sources: Design business layers that pull data from

4.

different databases seamlessly.

These features empower designers to build sophisticated semantic models that cater to

complex business needs.
