SAP HANA – How to create an Attribute View

Today we are going to create one of the artifacts of HANA called Attribute View.

SAP HANA has three types of views

1.Attribute View

2.Analytic View and

3.Calculation View

What is an Attribute View ?

Attribute views are like Dimension( like SAP Business Warehouse).These are view on one more tables built using joins.(like we create Database views in ABAP).

These are reusable artifacts and can be used in other views like Analytic view.


In this section we use the EPM data model shipped with SAP HANA system to create an attribute view.We use business partner data spread across different tables.The business partner information is needed wide across the system and hence we will be creating a reusable attribute view.

  1. All the artifacts are created under Content folder under a custom package.H1.png
  2. Enter the attribute view name and description and click on Finish.
