Create Simple View From Different Sources in SAP HANA

 

Creation of a simple view from different sources

From R3 table : (ETL Based replication)

Create a Data Store for SAP HANA (Target)

Create Datastore for SAP R3 (source)Import any table into SAP R3 data store (Required table)

Create a project

Create a batch job

Create workflow

Create dataflow {(Create ABAP data flow (Provide source datastore

(SAPR3), ABAP program name, ABAP program file name, Job name, and ABAP dataflow name)}

In ABAP dataflow take our imported table prom our data store (R3 DST) take query transformation, take transport connection, in query transformation map all fields (if there is no primary key), data transport connection provides a name for transport connection file

In data files take Query transformation, connect Query transformation to ABAP dataflow map all fields whatever you want, map Query transformation, and to get a table

(take from HANA Datastore)

Right-click on the job and execute it.

SAP HANA Studio

After Successful execution goes to the HANA modeler (Studio)

Go to modeler quick launch

Click on SQL editor

Enter the Query

[Create Schema <schema name>]

Expand system catalog (We have created a target HANA table under system catalog in Data Services)

Select our table, right-click and select a new view

In the Right side will get a table

Drag columns to column pane

Provide View name and our newly created catalog and execute

Refresh our nerdy created catalog and expand it

Under the cataloger expand the view and we will get a newly created view.

Note:

If you want to export our view to the client system in the form of CSR we can edit by selecting view preview

We can display in 2 ways

1) Tables

2) C ports

Right-click a view

Information Compares

It is a web-based environment which allows business users to upload data into the SAP HANA database and create information views

URL: http://sysname.domain.com:8090/ic/

It  is used to create calculated views

It creates information views by using Excel files Attribute view Analytic view and Calculated view

Which is coming from HANA DB

In Information composer, we need to upload data from a client system in the form of .xls, .xlsx, and .csv Compose the data: In composing we can combine two different databases by using joins and unions
