6 1. Introduction This document focuses on generating SAP NetWeaver Gateway services for SAP BW queries exposed via Easy Queries. Easy Query is one of the integrated services supported by SAP NetWeaver Gateway. SAP NetWeaver Gateway s SAP BW integration provides a generic tool allowing an administrator at customer side to easily expose existing SAP BW content as OData services. NOTE: Prior knowledge of the working of SAP NetWeaver Gateway is required to understand the information provided in this document. Now that you are here, we assume you are well aware of SAP NetWeaver Gateway. Read on to know more on one of the integrated services supported by Gateway, Easy Query! We will see how to generate SAP NetWeaver Gateway service for SAP BW queries exposed via Easy Queries. Gateway s SAP BW integration shall provide a generic tool allowing an administrator at customer side to easily expose existing SAP BW content as OData services. 2. Business Scenario With the advent of the smartphone and multi-touch tablet, entrepreneurs and customers have recognized the potential benefits of people centric applications for empowering employees with the right to instantly access data. People-centric applications very often include pieces of analytical information, which provides better understanding of the business context, increase process efficiency, and support decision-making. It is therefore important to make the analytical data and functions in our business systems available as consumption models accessible via OData. Analytic queries are the main tools for consuming analytical data. SAP NetWeaver Gateway and SAP Business Warehouse (BW) Integration enables the SAP BW content to be exposed as OData for SAP Analytic services for light weight mobile consumption. SAP NetWeaver Gateway: Provides an easy way of integrating SAP BW functionalities by using Multidimensional expressions (MDX) and Easy Query. Enables the adoption of existing analytical content in consumption scenarios based on OData. Provides a simple representation of analytical data sets. Provides support for simple interactions. 3. Prerequisites The Supported Release Information of SAP NetWeaver Gateway with Easy Query: GW SP05 BW 730 SP08 and above. BW 731 SP05 and above Note: SAP NetWeaver Gateway with EasyQuery is also supported in GW SP04 and BW 730 SP05, SP06, SP07. BW 731 SP00 to SP04, but with limited features.

7 4. Creating EasyQuery on BW The Query Design: BEx Query Designer is used to choose or define an EasyQuery. To define a query as EasyQuery proceed as follows: 1. Define an EasyQuery using BEx Query Designer. While defining choose one of the following options: EasyQuery Without Advanced Selection Options EasyQuery With Advanced Selection Options: Here Input parameters are provided by Characteristic Value Variable of processing type manual input / default value In simple words, User will be prompted to enter value for the Input Variable to fetch the Result. 2. Select By EasyQuery under Properties -> Extended tab, (refer the snapshot below for more details). More Details on EasyQuery on BW: Details on Configuring Easy Queries Details on Consuming Easy Queries Details on BEx Query designer

8 5. Generating OData Service for EasyQuery This section guides you to generate an OData service for an EasyQuery using the Service Builder application. To generate an OData services for an Easy Query proceed as follows: 1. Go to the transaction SEGW. Choose to create a new project. 2. Enter the details for the Project, Description, and Generation Strategy. In case the project needs to be transported the package should not be $TMP. 3. In the context menu of the Data Model (of the new project), select Redefine BW Query Service.. 4. Enter the details as explained below in the Wizard to Redefine BW Query service: Select Access Type as Controller for Easy Queries (SAP BW) Enter the RFC Destination (F4 is also available to select the RFC Destination) Enter the Query Name or Press F4 to select the EasyQuery from the defined BW System

Click to open the service document in the browser. The URL is as follows 7. Open the metadata by changing the above URL as below

12 7. Terminology When an EasyQuery is generated as an OData Service, the metadata of the OData Service will display OData specific terms. This section provides a list of EasyQuery terms and also OData specific terms for EasyQuery. Basic EasyQuery Terminologies Terms Query Query Characteristic : key, Text Characteristic members : Key, Text and Attribute Key Figures Characteristic Value Variables Description Access point for consuming logical data organized in a multi-dimensional cube structure. Query element used for creating perspectives on data via drill-down and slicing. Finite set of classifications representing the possible instances of a characteristic. A member has an ID, an associated text, and attributes. Facts for a combination of characteristic members. Facts are key figure values with a defined aggregation behavior. Example, summation, average, minimum, maximum, etc. Placeholders for values assigned by the consumer that may trigger extra logic before query execution, Example, Determines a certain perspective on the data cube by setting a filter for some characteristic. OData Specific terms for EasyQuery EasyQuery Terms OData Terms OData Terms (GW) Annotations Semantics Query with advanced Selection Query result Structures Query parameters Query Result <Query>Parameter s entity <Query>Result entity sap: semantics= "parameters sap: semantics= aggre gate Characteristic Dimension Property of a Result Entity sap: aggregation- Role="dimension" Key Figures Measure Property of a Result Entity sap: aggregation- Role="measure" Query Variables Parameter Property Property of the Parameter Entity Can be either sap: parameter= "mandatory sap: parameter= "optional Is Total Totaled Properties Totaled Properties sap: aggregationrole="totaledproperties-list"

13 RowID Entity Key Entity Key Here it is ID for each result entity

14 1. How to Create OData Service for Analytic Queries 8. Service Document 8.1 Service Document for a simple Query Let us analyze how a service document for a simple easy query is represented in OData (GW). In this case we shall consider a query which does not require input parameter to get the results. Below is the pictorial representation of the Service Document. The Service document for an EasyQuery without Input Parameter: Lists only the Query result Entity set Indicates that the Result Entity type represents the Query Result Structure Below is the OData representation of the above EasyQuery 8.2 Metadata for an EasyQuery with Advanced Selection Options Let us analyze how a service document looks in OData (GW) for an easy query which requires input for determining the Result. Below is the pictorial representation of the Service Document. The Service document for an EasyQuery with Input Parameter 1. Lists the query parameter entity set.

15 2. Indicates that the Parameter Entity type represents Query Parameters. 3. Identifies the properties of Parameter entity and creates a new entity for Value Help. Also lists the entity sets for Query Parameters 4. Lists the Query result Entity set. 5. Indicates that the Result Entity type represents Query Result Structure Below is the OData representation of an Easy Query

16 9. Metadata with Analytical Extension 9.1 Metadata for a simple EasyQuery Let us consider an easy query which does not have any advanced selection options. It just consists of four characteristics and two key figures. EasyQuery in Query Designer: OData representation of the above EasyQuery Metadata URI: In OData (GW) metadata shown above, apart from four characteristics and key figures you can see there is more information like ID -> Unique Identification of an Row in entity Totaled Properties -> List of properties on which result is totaled Formatted Property of the Key Figure-> Contains the formatted value of the key figure

17 9.2 Metadata for an EasyQuery with Advanced Selection Options Let us consider an easy query with advanced selection options. It just consists of three characteristics and three key figures. Also an advanced selection option Vendors which is a Characteristic Value Variable of processing type manual input / default value. EasyQuery in Query Designer: OData representation Of the above EasyQuery Metadata URI: <Host> :< Port>/sap/opu/odata/sap/BUSINESSPARTNERORDERS/$metadata

18 OData (GW) metadata shown above represents: Query result structures in a result entity. This entity has Dimension, key Figures and Formatted Key Figures. Query result structures also contains ID (Unique Identification of a Row in an entity) and Totaled Properties (List of properties on which result is totaled). Query Variables in a Parameters entity. This entity has Query Variable and Query Variable text. Parameters entity also contains Navigation Property Results which will enable for the navigation from parameters entity to Result entity. Below snapshots depicts the Navigation from Parameters to Result.

19 Value help for Query Variable is represented as a different entity. Below snapshot depicts the Association from Query Parameters Value Help entity.

20 10. Consuming the Service Now that we have metadata, we will analyze BW data in OData (GW) representation Interacting with a simple Query Here is a use case where the store Manager would like to analyze the sales order History (transactions) of an outlet. For easy understanding, below is the comparison between the Sales order history as seen in the SAP BW system and in OData (GW) format. Below is the Table and Chart representation of Sales Order history

21 Open the Ser vice Document of the OData (GW) gener ated ser vice. How to Create OData Service for Analytic Queries Now we will see how to analyze the same from OData (GW) generated service. To create a Query Operation URI follow the below mentioned steps: 1. Open the Service Document of the OData (GW) generated service as explained in section 6. Service Document for the EasyQuery in OData (GW) which has only Characteristics and Key Figures looks similar to the snapshot given below: 2. Create a Query URI for the Query Result entity. Add "href" attribute value to the URL i.e. <QueryName+Results>, forms the Query result Collection For example, Final URI for a Query Result entity looks like the link given below : <Host>:<Port>/sap/opu/odata/sap/ZCL_SALESORDERHISTORY_SRV/ SALESORDERHISTORYResults 3. Once the above URL is executed, all the non-aggregated values of the measures are returned in OData format. Below is the mapping of data in SAP BW System and the same data in OData format.

22 Now that we have results in OData format, let us see different cases of using the OData service: Case 1: Sales manager would like to fetch the Salesorder History for an Outlet (Fetch Nonaggregated Results on a Single Dimension ). OData Request: In the above URL, add the $select OData command specifing the properties representing measure (annotated as "sap: aggregation-role=measure") and the property representing a dimension (annotated as "sap: aggregation-role=dimension"). For example: YResults?$select=A4S3XRZGY594U6GMJ3SAB0BTQ4,A4S3XRZOMO7QJP35Z9MCNADSFW,A0V C_2STOR_T By executing the above URL, aggregated measure values of an outlet is returned in OData format which is shown below: Case 2: Sales manager would like to see the SalesOrderHistory of the Customers of an outlet (Fetch Aggregated Measure Values on more than one Dimension) OData Request: In the $select OData command specifing the properties representing measure (annotated as "sap: aggregation-role=measure") and more than property representing a dimension (annotated as "sap: aggregation-role=dimension"). For example:

23 <Host>:<Port>/sap/opu/odata/sap/ZCL_SALESORDERHISTORY_SRV/ SALESORDERHISTORYResults?$select=A4S3XRZGY594U6GMJ3SAB0BTQ4,A4S3XRZOMO7QJP 35Z9MCNADSFW,A0VC_2STOR_T,A0VC_2CUST By executing the above URL, the aggregated measure values i.e Salesorder of the Customers belonging to an outlet and also the Salesorder history of an outlet is returmed in OData format. Same is shown below : Case 3: Sales manager would like to see the PurchaseOrderHistory of a particular Customer of an outlet. (Fetch Aggregated Measure Values on a Dimension restricted to certain condition) OData Request: You could filter out the result set by using $filter OData Command. $filter OData command can be applied on those properties that are annotated "sap: aggregation-role=dimension". Note: $filter cannot be applied on those properties that are annotated as "sap: aggregation role=measure". $filter can be applied only on those propertiesfor which filterable enabled. For example:

24 <Host>:<Port>/sap/opu/odata/sap/ZCL_SALESORDERHISTORY_SRV/ SALESORDERHISTORYResults?$select=A4S3XRZGY594U6GMJ3SAB0BTQ4,A4S3XRZOMO7QJP 35Z9MCNADSFW,A0VC_2STOR_T,A0VC_2DPMT_T&$filter=A0VC_2CUST eq ' ' Tip: You could get the list of values for any dimension or dimension attribute by specifying them in $select OData command without any Measures. This gives you the list of members for the dimension. If you like to slice the aggregated values for a particular dimension, use ne operator with $filter OData command. In this usecase, the records belonging to Customer is retrieved first and then the aggregated value of each ProductCategory of an outlet is displayed. Same can be seen in the snapshot shown below.

25

26 Case 4: To fetch top N aggregated Values You could apply OData commands $top, $skip to your OData query request to fetch the top N aggregated value. OData Request : <Host>:<Port>/sap/opu/odata/sap/ZCL_SALESORDERHISTORY_SRV/ SALESORDERHISTORYResults?$select=A4S3XRZGY594U6GMJ3SAB0BTQ4,A4S3XRZOMO7QJP 35Z9MCNADSFW,A0VC_2STOR_T,A0VC_2DPMT_T&$filter=A0VC_2CUST eq ' '&$top=3&$skip=1 Note: OData Command $orderby is not supported. Case 5: Sum of aggregated Measure Values You could apply OData command $select on measure values and totaledproperties (annotated as 'sap-aggregation-role="totaled-properties-list"' in the Results Entity) OData Request: Results?$select=A4S3XRZGY594U6GMJ3SAB0BTQ4,A4S3XRZOMO7QJP35Z9MCNADSFW&Total edproperties 10.2 Interacting with a Query with Advanced Selection Options In this use case we have a business partner (referred as BP) who has ordered for a product with product ID and receives the Purchase Order details for the same. Now the BP likes to analyze the Purchase Order history of the products which was ordered. The below snapshot depicts the table and chart representation of the purchase order history details in SAP BW system.

27 Now we will see how to analyze the same from OData (GW) generated service. To create a Query Operation URI follow the below mentioned steps: Open the Ser vice Document of the OData (GW) gener ated ser vice. 1. Open the Service Document of the OData (GW) generated service as explained in section 6. Service Document for the EasyQuery in OData (GW) which has only Characteristics and Key Figures and Characteristic Value Variables looks similar to the snapshot given below: 2. Below is the step by step procedure of forming the Query URL. Search for Parameters in the service document and add the "href" attribute value to the URL. For example: href attribute value >/ <Host>:<Port>/sap/opu/odata/sap/BUSINESSPARTNERORDERS/ BUSINESSPARTNERORDERS Now add $select = <Query Variable> to the above URI. This will display List of Entries for the selected <Query Variable> Host>:<Port>/sap/opu/odata/sap/BUSINESSPARTNERORDERS/ BUSINESSPARTNERORDERS?$select=A0P_BP_SUPP From the response choose one entry and replace < href attribute value >?$select=< Query Variable> with value of "<link href="entitysetname('value') > For example: <Host>:<Port>/sap/opu/odata/sap/BUSINESSPARTNERORDERS/ BUSINESSPARTNERORDERS(' ') Adding "/Results" to the above link forms the query result Collection For example:

28 Note: = V1)/Results <Host>:<Port>/sap/opu/odata/sap/BUSINESSPARTNERORDERS/ BUSINESSPARTNERORDERS(' ')/Results URL always first identifies values for the parameters in the parameter entity set and then navigates to the query results for this parameterization. Example, service/query (p1 == v1)/results. Even if a query parameter is annotated with sap:parameter="optional", the Query Parameter should be part of the URL. 3. Once the above URL is executed, the results are aggregated based on the Input Variables and the aggregated results is displayed in OData format as shown below : Below is the mapping of data in SAP BW System and the same data in OData format

29 Now lets see some of the usecases for the above generated OData service. Case 1: To Fetch the list of Values for a Query Variable You could apply OData command $select on an any Query Parameres (annotated as sap:parameter="optional" or sap:parameter="mandatory") to fetch the list of values. OData Request: <Host>:<Port>/sap/opu/odata/sap/BUSINESSPARTNERORDERS/ BUSINESSPARTNERORDERS? $select=a0p_bp_supptext,a0p_bp_supp Note: At a time $select can be applied only on one Query Parameter and the associated text. Case 2: To fetch the list of Values for a dependent dimension (Query parameter) You could apply $select OData command on the QueryParameter for which you would like to fetch list of values and apply $filter on the dependant dimension. Now how do you identify if a Query parameter has a dependant diimension. Well you can identify this by checking if the Queryparameter has an annotation sap:superordinate="dependant Dimension" For example: <Property Name="P1" Type="Edm.String" Nullable="false" MaxLength="10" sap:parameter="optional" sap:super-ordinate="dependant dimension sap:filterable="false"/> OData Request: <Host>:<Port>/sap/opu/odata/sap/BUSINESSPARTNERORDERS/ BUSINESSPARTNERORDERS? $select=p1&$filter=p2 eq V1 Note: $filter can be applied only on those parameters which are filterable. 11.
