Exercise 2: Creating Attribute ViewsExercise Duration: 20 Minutes

Exercise ObjectivesAfter completing this exercise, you will be able to: Create Standard and Derived Attribute Views Create Analytical Views Create and Use Calculated Attributes in Attribute Views

Business ExampleYou are at a customer site where SAP_HANA_DEMO schema is available. Information of the Business Partners is dispatched in several tables. The purpose will be to regroup Information of the Business Partners and to analyze Purchase Orders by Product and Partners.

So you have been asked to build Attribute Views and Analytic Views for HANA.This section takes you through the process to create the Attribute Views and Analytical Views to be used for reporting.

Task 1:Create your packages in Content folder. For ex. STUDENTXXFor HYD (use STUDENT01 -20)For Gurgaon (use STUDENT21 -30)For Mumbai (use STUDENT31 -35)For Bangalore (use STUDENT36 -50)

Close all open views prior to creating a new attribute view for Business Partners.1. Create an attribute view AT_HA300_UNIT3_BP_TRAINXX (xx being your student number), with description Business Partners. Use your package STUDENTXX. (If it does not exit, please create a new one.)Attribute Type: StandardPress Next.Add the following tables in the Data Foundation, from the SAP_HANA_DEMO schema, to define the view and click Finish when done:BusinessPartnerAddresses

Figure 70: Add tablesJoin tables with a Inner join and cardinality 1:1.

Figure 71: Creating joins

Add to Output (right click on the table on the Data Foundation tab) from BusinessPartner Table:PARTNERID Key AttributeEMAILADDRESS AttributePHONENUMBER Attribute

Add to Output from Addresses Table as AttributesADDRESSIDCOUNTRY

Figure 72: Add columns to output

In the Semantics view, define all columns as attributes, making PARTNERID a Key Attribute Figure 73: Define semantics

Activate.

View the logs. Dependent objects that are already active should not get reactivated.From the context menu of ATTRVIEW_STUDENTXX, view the results by selecting Data Preview.In the Data Preview, select the Raw Data tab to see the actual data.

There is also a provision to add CALCULATED COLUMNS to the Attribute view.

Right click on the Calculated Columns to create a new column. (We are adding a new Column MOD_PHONE1 to the view).

Enter the name of the column and description. Provide a valid expression for the calculated column.

Activate.

View the logs. Dependent objects that are already active should not get reactivated.From the context menu of ATTRVIEW_STUDENTXX, view the results by selecting Data Preview.In the Data Preview, select the Raw Data tab to see the actual data.

Close.

Task 2:Create an attribute view for Products.1. Create an attribute view AT_HA300_UNIT3_PD_TRAINXX (XX being your student number allocated), with description Products.Attribute type: Standard.Add PRODUCTS table in the Data Foundation tab.Finish. Figure 74: Add tablesDefine the following fields (add to Output doing a right click on the table in the Data Foundation tab):PRODUCTID Key Attribute.TYPECODE Attribute.CATEGORY Attribute.SUPPLIERID.PARTNERID Attribute.

In the Semantics view, define all columns as attributes, makingPRODUCTID a Key Attribute

Figure 76: Define semanticsSave and Activate.From the context menu of AT_HA300_UNIT3_TRAINXX, view the results by selecting Data Preview.In the Data Preview, select the Raw Data tab to see the actual data.Close.

Task 3:Create an Analytic View for Purchase Orders.1. Create an analytic view AN_HA300_UNIT3_PO_TRAINXX (xx being your student number allocated), with description Purchase Orders. .Press Next.Add the following tables in the Data Foundation tab:EPM.PO.HEADEREPM.PO.ITEM Figure 77: Add tablesAdd the following Attribute views from your Package, STUDENTXX:AT_HA300_UNIT3_BP_TRAINXX andAT_HA300_UNIT3_PD_TRAINXX Figure 78: Add Attribute ViewsChoose OK.

Figure 79: Set propertiesIn the DATA FOUNDATION, join the two tables.Table PO.HEADER is the left table.Join the field PURCHASRORDERID from PO.HEADER to the PURCHASEORDERID.PURCHASEORDERID field in PO.ITEM.For the join properties, select Referential join and a cardinality of 1:n for both joins in the properties of the join.From the table PO.HEADER, define the following fields as Attributes PURCHASEORDERIDPARTNERID.PARTNERIDFrom the table PO.ITEM, define the following fields as Attributes PURCHASEORDERITEMPRODUCTID.PRODUCTIDGROSSAMOUNTNETAMOUNT

In the logical view, join the data foundation to the Procduct view with the following fields.PRODUCTID to PRODUCTID_PRODUCTID (Product View).Use referential join and cardinality of n:1.Then, join the data foundation to the Business Partner view with the following fields.PARTNERID to PARTNERID_PARTNERID (Business Partner View).Use referential join and cardinality of n:1.

Figure 82: Define joins

In the Semantics screen, define the column PURCHASEORDERID & PURCHASEORDERITEM as an attribute, and the columns GROSSAMOUNT and NETAMOUNT as measures.

Figure 83: Define semanticsSave and Activate.View the Log. From the context menu of AN_HA300_UNIT3_PO_TRAINxx, select Data Preview to review the contents.Close.

Task 4:Create a derived attribute view from the Product view.1. Try to add the Attribute View, AT_HA300_UNIT3_PD_TRAINXX , to the analytic view AN_HA300_UNIT3_PO_TRAINXX again, by dragging theAttribute View from the Navigator to the Logical View of the Analytic View.What is the result? (Not possible).Note: To add another Attribute view to an existing Analytic View, just select the Attribute from the Navigator and drag it into the Logical view of the Analytic View. If you try to drag an AttributeView into an Analytic View that already exists in the Analytic View, it will not work.If your model requires that you have 2 identical Attribute Views in the sameAnalytical View, you will have to create a Derived Attribute with Aliases.Create a new Attribute View, AT_HA300_UNIT3_PD_DERIVED, derived from AT_HA300_UNIT3_PD_TRAINXX.Note: To create a Derived Attribute View, choose Subtype: Derived from within the New Information View screen. Figure 85: Create a derived attribute

Can you modify the derived attribute view?Save.Activate the Derived Attribute View, AT_HA300_UNIT3_PD_DERIVED.
