In this tutorial, you will go through all the steps to import data from a MS Excel Spreadsheet, model a simple Calculation view and view the results in a pivot table using the HANA MDX connector from MS Excel. You will first create the basic setup within an XS Project.


DEPRECATED: SAP HANA XS Classic is deprecated as of SPS02. Please use XS Advanced, and learn about how to get started with the new mission Get Started with XS Advanced Development.


Step 1: Download and Install SAP HANA Client

First, you will need to download and install the SAP HANA Client to enable the MDX Connector. You can find it in the Marketplace, in the SAP Software Download Center:

Download SAP HANA Client from SAP Software Download Center

Follow the instructions from the installer to complete the installation.

Step 2: Create the XS Project and Core Data Services artifacts

In SAP HANA Studio, from the SAP HANA Development perspective, create an XS Project by selecting File->New->XS Project. If you do not see the XS Project option, go into Other and look for it under the Application Development menu inside SAP HANA.

Create XS project

Click on Next, choose a repository, add a name for a package and untick the Add project Folder as Subpackage.

Choose repository and name package

Click Next, add a name for a schema and for the Data Definition (.hdbdd) file

Add schema and DDL

You can now declare a context in a Core Data Services (CDS) artifact. This context will serve as a group for the two design-time entities (tables) that will hold the data you will import and the data types you will create.

Enter the following code into the .hdbdd file:

namespace mdx_parks;

@Schema : 'PARK'
context parks {

/**`Type` is to declare reusable field or structure declarations. **/

Type tyObjectID : String(8);
Type tyParkID : String(7);
Type LString : String(200);
Type MString : String(80);
Type SString : String(20);
Type TString : String(2);

/** An entity becomes a table **/

entity Park {

	key OBJECTID : tyObjectID;
	key ParkID : tyParkID;
	ParkName : MString;
	ParkType : SString;
	ParkStatus : SString;
	DevelopmentStatus: SString;
	ParkPlanningArea : SString;
	MgtPriorty : SString;
	MgtAgencyName : MString;
	MgtAgencyType : SString;
	Landowner : MString;
	OwnerType : SString;
	Acreage : Decimal(10,2);
	AcreSource : SString;
	Address : MString;
	CityMuni : SString;
	County :  SString;
	State : TString;
	StreetNum : String(6);
	StreetDirection : TString;
	StreetName : MString;
	StreetType : String(4);
	Zip : String(5);


/**	The following fields in the file have been lef out:
StatusCmnt, Comments, Classic**/

entity Amenities {
	key ID : String(32);
	key ParkID : tyParkID;
	park: Association[1] to Park on park.ParkID = ParkID;
	AmenityType : MString;
	CourtCount : Integer;
	DescriptionText : LargeString;
	HasSwingset : String(5);


/**Fields Park Name, FieldCount,FieldSurface, AgeGroup, Address, Latitude, Longitude, CreatedDate,UpdatedDate,FID
 not included **/


The structures defined for these three entities match those of the files we will use later, except for some fields that have been intentionally left out.

Right-click on the project, go down to Team and click on the Activate All button.

Activate the entire project
Step 3: Grant permissions to the newly created schema

From the Systems tab, open the Security folder and look for your user ID. Double-click on it to open your User Administration page.

System Tab

Click on the Object Privileges tab and the on the + sign to add the schema you need access to:

Open user

Select the schema you have just created:

Select schema

Note: You may need this done by a user with administration permissions.

Flag permissions

Flag permissions to Delete, execute, insert, select and Update your new schema.
Once finished, press F8 or click on the green arrow on the top right corner to deploy the changes.

You can now go into the Systems tab and look for the Schema and tables:

Flag permissions
Step 4: Import data into your tables

This example uses data from the Open Data City of Boise site. If you choose another dataset, you need to adapt the entities and types created in the previous step to match the structure of that dataset.

The datasets in this example are the Boise Parks Facilities Open Data and the Boise Parks and Reserves Open Data CSV files.

Go into File and then Import.

File -> Import on HANA Studio

In the SAP HANA Content folder, choose Data from Local File and then click on Next.

SAP HANA -> Content

Choose your target system (where your schema and tables are):

Choose target system

Click on Browse to select one of the two files you will import. This example starts with Boise_Parks_and_Reserves_Open_Data.csv, which contains the date for the table Park. You could also start with Boise_Parks_Amenities_Open_Data.csv, which contains the data for the table Amenities. once you select the file, click on Open.

Note: You could also use .xlsx or .xls file formats.

Choose File

Click on the Header Row Exists to indicate that the first row contains the names of the columns. Click on Select Table to search for the table to which you will import the file. This example uses the table Park.

Select table

Click on Next. If you are importing a file with a Header Row and the names of the rows match the names in the table, you can choose the Map By Name, like in this example. If you do not have a header row or the names do not match, you can choose to perform the mapping manually by dragging the fields from the source file on the left to the target table on the right.

Map by name

Perform the same import procedure with the Amenities table using the Boise_Parks_Amenities_Open_Data.csv file.

Right-click on the tables to Open Data Preview and see the files loaded. You can quickly explore the data in the Distinct Values and Analysis tabs:

Data Preview

Hint: If you click on the Show Log button on the top right corner of the data preview in SAP HANA Studio, you can see the SQL Query and the server processing time.

Step 5: Create a Calculation View

You will now create a Calculation View. A calculation view can perform complex calculations joining different tables, standard views and even other calculation views as sources.

From the Project Explorer tab in SAP HANA Studio, right click on the project, then on New and then look for the Calcuation View under SAP HANA / Database Development

New Calculation View

Enter the name for your calculation view and click on Finish.

New Calculation View Name

Add two projection nodes by dragging and dropping Projection nodes from the Nodes lateral bar. These nodes will be used to join the parks to their Amenities and add a filter later.

Drag and drop projection nodes

Hover on the nodes and a + sign will appear on the right.

Add table clicking on the plus sign

Click on it to select the one of tables (either Park or Amenities) to be projected. Repeat the same for the other table so you can select all of the fields for output. You can either click on the circle on the left of each individual field or right click on the top of the table node and select Add all to Output.

For the Amenities, leave out the DescriptionText field from the output as it is not supported by this type of view.

Add all fields to output

Drag and drop a Join node from the Nodes bar on the left. To connect the tables, drag and drop the circles on the top of each Projection node into the Join node.

Add Join

Click on the Join Node to connect the key fields by dragging the ParkID from the left into the ParkID field from the right:

Drag ParkID

Add all the fields to output (except for the ParkID field from amenities, to prevent it from being duplicate) and set the Join Type to Left Outer so that Parks that do not have any amenities are also included in the results.

Left outer

Finally, drag and drop the circle on the Join node into the Aggregation node. Add all the fields in the Aggregation to Output and click on the Semantics node.
Use the Auto Assign button to automatically set the type (measure or attribute) for each field.

Assign semantics and auto layout

The Auto Layout button at the bottom of the graphic model makes the diagram prettier.

Activate your view using the green arrow on the top:

Activate the View

And click on Raw Data to see your results:

Raw Data
Step 6: Connect to your instance using the MDX connector

Open a new spreadsheet in MS Excel. In the Data ribbon, choose From Data Connection Wizard in the Other Sources menu.

Data Connection Wizard in MS Excel

Choose Other/Advanced and click Next.

If you completed Step 1 successfully, you will see HANA MDX Provider at the bottom. Select it and click on Next.

MDX Provider

Enter the connection details to your SAP HANA database and test the connection before clicking on OK.

Connection details for hana

Hint: You can right-click on the system, and open Properties to see your IP or host name followed by port 3xx15, where xx is your instance number.

After the connection is established, choose the package (database to MS Excel) and the calculation view (also known as, Cube) and then click Finish.

Choose view

Review the Import Data options. Keep the Pivot Table and click on OK.

Excel Pivot

You can now use Excel to execute OLAP queries against SAP HANA and create Pivot Tables and Pivot Charts.
