By contrast, if you create an analytic view for one specific use case in which you want a particular attribute to behave differently than it does in the attribute view to which it belongs, you can define it as a private attribute. Measures Measures are simple measurable analytical elements. Measures are derived from analytic and calculation views. ● Simple Measures A simple measure is a measurable analytical element that is derived from the data foundation. For example, PROFIT. ● Calculated Measure Calculated measures are defined based on a combination of data from OLAP cubes, arithmetic operators, constants, and functions. For example, calculated measures can be used to calculate the total sales of a product across five regions, or to assign a constant value to a measure for a calculation. ● Restricted Measure Restricted measures are used to filter the value based on the user-defined rules for the attribute values. ● Counters Counters add a new measure to the calculation view definition to count the recurrence of an attribute. For example, to count how many times Product appears. Note: You can choose to hide the attributes and measures that are not required for client consumption. For example, for a complex calculation that is derived from a series of computations, you can hide the levels of computations that are not required for reporting purposes. 6.2.2 Attribute Views Attribute views are used to model an entity based on the relationships between attribute data contained in multiple source tables. For example, customer ID is the attribute data that describes measures (that is, who purchased a product). However, customer ID has much more depth to it when joined with other attribute data that further describes the customer (customer address, customer relationship, customer status, customer hierarchy, and so on). You create an attribute view to locate the attribute data and to define the relationships between the various tables to model how customer attribute data, for example, will be used to address business needs. You can model the following elements within an attribute view: ● Columns ● Calculated Columns 104 P U B L I C © 2012 SAP AG. All rights reserved. SAP HANA Developer Guide Setting Up the Analytic Model
● Hierarchies Note: In the Semantics node, you can classify the columns as attributes and build calculated columns of attribute type. Note: For more information about the attributes and hierarchies mentioned above, see sections Attributes and Measures, and Hierarchies. You can choose to further fine-tune the behavior of the attributes of an attribute view by setting the properties as follows: ● Filters to restrict values that are selected when using the attribute view. ● Attributes can be defined as Hidden so that they can be used in processes but are not visible to end users. ● Attributes can be defined as key attributes and used when joining multiple tables. ● The Drill Down Enabled property can be used to indicate if an attribute is available for further drill down when consumed. Attribute views can later be joined to tables that contain measures within the definition of an analytic view or a calculation view to create virtual star schema on the SAP HANA data. 6.2.3 Creating Attribute Views Attribute views are used to define joins between tables, and to select a subset (or all) of the table's columns and rows. The rows selected can also be restricted by filters. One application of attribute views is to join multiple tables together when using star schemas, to create a single dimension table. The resultant dimension attribute view can then be joined to a fact table via an analytic view to provide meaning to its data. In this use case, the attribute view adds more columns and also hierarchies as further analysis criteria to the analytic view. In the star schema of the analytic view, the attribute view is shown as a single dimension table (although it might join multiple tables), that can be joined to a fact table. For example, attribute views can be used to join employees to organizational units which could then be joined to a sales transaction via an analytic view You have imported T009 and T009B tables for creating attribute view of type Time. Use this procedure to create a view that is used to model descriptive attribute data (that does not contain measures) using attributes. Tip: You need this view for creating a multidimensional view. 1. Set Parameter 1. In the Modeler perspective, expand the Content node of the required system. 2. Expand the package to which you want to save your information object. 3. In the context menu of Attribute Views node, choose New . 4. Enter a name and description for the view. 5. To create data foundation for the view, perform substeps of the required scenario given in the table below: Scenario Substeps Create a view with table attributes.
