This document provides an overview of Attribute Views in SAP HANA. It defines Attribute Views as sets of dimensions or master data that can be joined with fact tables for analytical purposes. It describes the different types of Attribute Views, including standard, derived, and timed Attribute Views. It also covers the different types of joins, hierarchies, and cardinalities used to structure Attribute Views. Finally, it outlines the steps for creating an Attribute View in SAP HANA.

2. SAP HANA Attribute View – Create
Attribute View in 9 Easy Steps
In previous topic we learn little and recall the significance of information
modelling in SAP HANA. Information models or Views are logical
frameworks or run-time objects which structures data from one-dimensional
databases into multi-dimensional data structures for analytical purposes. The
information views do not store data physically in SAP HANA. The logic of a
view is stored in HANA and every time a reporting tool requests the view, the
system fetches the data according to the blueprint of the view from the data
source and presents it to the user.
What is SAP HANA Attribute View?
The Attribute View in SAP HANA is a set of dimensions or master data which
can be joined with the fact table in an Analytic View. An Attribute View can be
created by taking data from one or more data tables. The attribute shows
relationships between different attributes. The attributes can be Customers,
Region, Product, Period etc. In an Attribute View, joins can be made between
two master data tables, a text table, and a master data table, etc.

3. Types of Attribute View
• Standard Attribute Views
These views create by table fields among different column store tables by using
joins in SAP HANA.
• Derived Attribute Views:
It is an Attribute View created using another existing Attribute View. It will
open in read-only mode, we cannot edit the derived Attribute view. The only
editable field in the created Attribute View is the description. It will act as a
reference to the base Attribute view. Any modification to the base Attribute
View will reflect in the created Attribute View.
• Timed Attribute Views:
Timed Attribute View stores the time-dependent data. It is created against
calendar tables – M_FISCAL_CALENDAR (or) time tables –
M_TIME_DIMENSION, M_TIME_DIMENSION_YEAR,
M_TIME_DIMENSION_MONTH and M_TIME_DIMENSION_WEEK. All these
tables stores in _SYS_BI schema.

4. Types of Joins
Tables from data sources join in different ways to create an Attribute View in
SAP HANA. The join types are:
Referential Join
• Inner Join
• Left Outer Join
• Right Outer Join
• Text Join
Along with defining the join type of the Attribute View, the cardinality of tables
is also important to specify. The cardinality can be 1:1, 1: N or N:1.

5. Types of Hierarchies
Along with cardinality, and join type, dimensions in Attribute View arranges in
hierarchies. There are two types of hierarchies in which attributes in a set gets
arrange; Level hierarchy and Parent-Child hierarchy.
• The level hierarchy follows a rigid pattern of root and child nodes where
successive attributes can be accessed only in the order they were created.
• A parent-child hierarchy is like a tree structure where there are multiple
sub-nodes of a root node which can further extend to an undecided length.
Thus, the tree-like structure has unbalanced root nodes.
Creating an Attribute View in SAP HANA
Before we learn how to create the Attribute View in SAP HANA Modeler, let
us understand the process flow in order to create a complete and proper
Attribute View.
