6 Creating and Running the Mapping

This chapter describes how to create and run the mapping.

This chapter includes the following sections.

6.1 Creating the Mapping

Now that the source and target data models are created, it is possible to create a mapping to integrate data from the T005T and T005U SAP tables to the WS_GEO_DS Oracle table.

To create the mapping, perform the following steps:

6.1.1 Create the Mapping

  1. Open Designer.

  2. In the Projects tree view, expand the SAP Demo Project.

  3. Expand the SDE_SAP_GeoDimension folder.

  4. Select the Mappings node.

  5. Right-click and select New Mapping.

  6. In the Mapping Definition tab, enter the mapping name: SDE_SAP_GeoDimension.W_GEO_DS.

  7. Save the mapping.

6.1.2 Define the Source and Target Datastores

To define the source and target datastores:

  • In the Models tree view, select the WS_GEO_DS datastore from the Oracle Target Model.

  • Drag this datastore into the Target Datastore area of the Logical diagram. (Right area of the Logical diagram)

  • In the Models tree view, select the T005T Country Names datastore from the SAP ERP Source model.

  • Drag this datastore into the Sources area of the Logical diagram.

  • Perform the same operation for the T005U Taxes: Region Key datastore from the SAP ERP Source model. The Sources area of the Logical diagram should look as shown below:

6.1.3 Define Joins between Sources

To create joins between the source datastores of a mapping:

  1. In the Sources area of the Logical diagram drag the SPRAS attribute from the T005T Country Name datastore onto the SPRAS attribute in the T005U Taxes: Region Key datastore.

  2. On the Create Lookup or Join popup, select Join and click OK. This defines the first join on the Language Key identifier, as shown below:

    Description of image042.jpg follows
    Description of the illustration image042.jpg

  3. Drag the LAND1 attribute from the T005T Country Name datastore onto the LAND1 attribute in the T005U Taxes: Region Key datastore. The join is extended with the new attributes. In the Properties panel, you can see the join clause: T005T.SPRAS=T005U.SPRAS AND T005T.LAND1=T005U.LAND1

  4. In the Properties panel, select Generate ANSI Syntax and Join Order options, and make sure that the Execute on Hint option is set to Source as shown below:

    Description of image044.jpg follows
    Description of the illustration image044.jpg

  5. Make sure that table number of T005U is smaller than that of T005T. In 1:n relationships the parent table has to be the first in a join.

6.1.4 Create the Mappings

To create the mappings of the target datastore:

  1. Select the LANGUAGE KEY attribute from the target datastore.

  2. Drag the SPRAS attribute from the T005T Country Names source datastore onto the LANGUAGE KEY attribute of the target datastore.

  3. Make sure that the Execution on Hint option is set to Source. The mapping should look as shown below:

    Description of image046.jpg follows
    Description of the illustration image046.jpg

  4. Repeat this operation to perform the following simple mappings:

  • W_GEO_DS.COUNTRY = T005T.LAND1

  • W_GEO_DS.COUNTY = T005T.LANDX

  • W_GEO_DS.STATE_PROV = T005U.BLAND

  • W_GEO_DS.NATIONALITY = T005T.NATIO

6.1.5 Define the Mapping Flow

To define the mapping flow:

  1. Select the Physical diagram. The Physical diagram looks as shown below;

    Description of image048.jpg follows
    Description of the illustration image048.jpg

  2. In the target group, select the access point for the source group that contains both the T005T and T005U datastores. This source group represents the source dataset made up of two joined SAP ERP datastores.

  3. In the Property panel, under Loading Knowledge Module, select LKM SAP ERP to Oracle (SQLLDR) or LKM SAP ERP to SQL from the Loading Knowledge Module drop-down list.

    1. If you are using FTP for the data transfer, please set the FTP_TRANSFER_METHOD option to FTP. If the FTP server is installed on your ODI agent machine, select NONE.

    2. Leave other options as they are.

  4. In the target group, select the target Oracle database, which is also used as the staging area for this mapping.

  5. In Property panel, under Integration Knowledge Module, select IKM Oracle Incremental Update from the Integration Knowledge Module drop-down list.

  6. Set the IKM options as follows:

    1. Select No for the FLOW_CONTROL option.

    2. Leave other options as they are.

  7. From the File menu, click Save and close your mapping.

6.2 Running the Mapping

This section contains the following topics.

6.2.1 Running the Mapping

To run the mapping:

  1. In the Projects tree view, expand the SAP Demo Project

  2. Expand the SDE_SAP_GeoDimension folder.

  3. Expand the Mappings node.

  4. Select the SDE_SAP_GeoDimension.W_GEO_DS mapping.

  5. Right-click and select Execute.

  6. In the Execution window that appears, click OK.

  7. Click OK in the Session Started window.

What happens when you run the mapping?

First, Oracle Data Integrator creates an ABAP program that does the following:

  • It performs the extraction of the data on the SAP engine. In this example, the extraction joins the two source tables and then returns the joined resultset in an extraction file.

  • It uploads the extraction file into a FTP data server. This FTP host is specified via the File Logical Schema called File Server for SAP ABAP. This Logical Schema is mapped to a Physical Schema and therefore a data server in the given context. This data server contains the connection information for the FTP host.

Then, the ABAP code is uploaded using the OdiSapAbapExecute tool. The ABAP program is pushed into the SAP Function group given in the SAP_FUNCTION_GROUP LKM option. This phase can be suppressed by setting the UPLOAD_ABAP_CODE LKM option to No.

The ABAP code is executed also by the OdiSapAbapExecute tool. At the end of the ABAP code execution, the extraction file is available in the FTP host.

The Oracle Data Integrator agent is able to download this extraction file from the FTP host, or directly access it, depending on the FTP_TRANSFER_METHOD specified in the IKM option.

Finally, when the agent accesses the extraction file, it uses SQL*Loader or a JDBC Connection to load this file into the Oracle/non-Oracle staging area. The rest of the integration process takes place within the Oracle/non-Oracle engine.

6.2.2 Review the Mapping Execution

To review the mapping execution:

  1. Connect to Operator.

  2. In the Operator, select the Session List tree view.

  3. Expand the All Executions node in this tree view.

  4. The latest session is the first entry of this list.

  5. Double click the SDE_SAP_GeoDimension.W_GEO_DS node to see the session details and the number of lines processed.

6.2.3 Review the Resulting Data

To review the resulting data:

  1. In the Designer, in the Models tree view, expand the Oracle Target Model.

  2. Select the W_GEO_DS datastore, right-click and select Data to view the data integrated into the target Oracle table.
