tELTSAPMap Standard properties

These properties are used to configure tELTSAPMap running in the Standard Job framework.

The Standard tELTSAPMap component belongs to the ELT family.

The component in this framework is available in all Talend products.

Basic settings

Property Type

Either Built-In or Repository.

  • Built-In: No property data stored centrally.

  • Repository: Select the repository file where the properties are stored.

Use an existing connection

Select this check box and from the list displayed select the relevant connection component to reuse the connection details you have already defined.

Information noteNote: When a Job contains the parent Job and the child Job, if you need to share an existing connection between the two levels, for example, to share the connection created by the parent Job with the child Job, you have to:

  1. In the parent level, register the database connection to be shared in the Basic settings view of the connection component which creates that very database connection.

  2. In the child level, use a dedicated connection component to read that registered database connection.

For an example about how to share a database connection across Job levels, see Talend Studio User Guide.

SAP Map Editor

The ELT Map editor allows you to define the output schema and build graphically the SQL statement to be executed. The column names of schema can be different from the column names in the SAP system.

Server Type

Select the type of the SAP server to be connected, either Application Server or Message Server.

Client

The SAP system client ID.

UserId and Password

The user connection ID and password.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

Language

The language of the SAP system.

Host name

The name or IP address of the host on which the SAP server is running.

System number

The SAP system number.

This property is available only when Application Server is selected from the Server Type drop-down list.

System ID

The SAP system ID.

This property is available only when Message Server is selected from the Server Type drop-down list.

Group Name

The SAP group name.

This property is available only when Message Server is selected from the Server Type drop-down list.

Batch size

Specify the maximum number of records that can be written in each file generated by the SAP system.
File protocol

Select either FTP or the secure alternative SFTP.

FTP host

Specify the IP address or the host name of the FTP server.

FTP port

Specify the listening port number of the FTP server.

FTP user and FTP password

Specify the user authentication data to access the FTP server.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

FTP directory

Specify the directory where the files generated by the SAP system will be saved.

Data filename prefix

Specify the prefix of the files generated by the SAP system.

Specify a shared destination

Select this check box and specify the shared destination in the Shared destination name field displayed. The shared destination allows the SAP components to use the shared destination on the Talend Runtime when they are executed as part of an ESB Route or ESB Data Service within the Talend Runtime container OSGi Environment.

Besides specifying the shared destination name in the component, you also need to setup the SAP DataSource for the Talend Runtime. What you need to do to define the SAP DataSource and how to configure it are described in the readme.txt provided in the Talend ESB package within the /add-ons/datasource/sap folder.

Note that if you use the component's own connection configuration, your SAP connection will be closed at the end of the component. To prevent this from happening, use a shared destination with its name specified.
RFC server url

Enter your RFC server URL in the field provided.

The Studio uses the RFC server as the streaming proxy to support high volume of data extraction without the need to store information on a third-party transfer protocol such as FTP or SFTP.

This field becomes visible when you select Use the RFC server in the Advanced settings view.
Package size

Specify the number of records for each package. By default, the value displays 10000.

In case you have a value higher than 10000, for example, 12000, the Studio creates two packages - one package that contains 10000 records and another package that contains 2000 records.

This field becomes visible when you select Use the RFC server in the Advanced settings view.

Connection id

Enter the ID of the connection established by the SAP RFC server, that is, the name of the SAP connection configuration file (the extension not included).

An SAP RFC server can establish multiple SAP connections based on the SAP connection configuration files. By default, the SAP connection configuration files are stored in $TSAPS_HOME/conf/named-connectiond, where $TSAPS_HOME is the directory where the Talend SAP RFC Server has been installed. If you cannot find the desired SAP connection configuration file in the default directory, check the directory specified by the named.connections parameter in the tsap-rfc-server.properties file.

This field is available when Use the RFC server is checked in Advanced settings view.

Information noteNote:
  • This field is available only when you have installed the R2021-08 Studio Monthly update or a later one delivered by Talend. For more information, check with your administrator.
  • The $TSAPS_HOME/conf/named-connectiond directory, the named.connections parameter, and SAP connection configuration files are effective only if you have applied Patch_20210820_TDI-45536_v1-7.3.1.

Number of threads to extract the data from SAP

Set the number of threads for data extraction. The default is 2.

This option is available when you select the Use the RFC server option in the Advanced settings view.

Information noteNote: This option is available only if you have installed the R2020-08 Studio Monthly update or a later one delivered by Talend. For more information, check with your administrator.

Kafka topic partition count

Set the Kafka topic partition count. The default is 2.

This option is available when you select the Use the RFC server option in the Advanced settings view.

Information noteNote: This option is available only if you have installed the R2020-08 Studio Monthly update or a later one delivered by Talend. For more information, check with your administrator.

Max time to wait for more data

Set the maximum time period (in seconds) for the client to wait for more data of a Kafka topic when an error occurs. If no data is received when the period expires, the stream will be cancelled. The default is 60.

This option is available when you select the Use the RFC server option in the Advanced settings view.

Information noteNote: This option is available only if you have installed the R2020-08 Studio Monthly update or a later one delivered by Talend. For more information, check with your administrator.

Advanced settings

Use the RFC server Select this check box if you wish to directly extract high volumes of data from an SAP application. When you select this option, the Connection configuration section displays the fields for the RFC server url and Package size. For more information, see the corresponding description of those fields in the Basic settings view.
Kafka Properties When you select the Use the RFC server option, the window displays the Kafka Properties table. Kafka, or Apache Kafka, is an open-source distributed streaming platform. For more information about Kafka, refer to https://kafka.apache.org/.

Enter your Kafka information in the fields provided.

Use space to replace the control characters in data

Select this option to replace special characters in data with spaces. Some characters in data (for example, \n) may affect data parsing because they are treated as control characters. This option prevents this by replacing the special characters with spaces.

This option is selected by default.

SAP Properties

If you need to use custom configuration for the SAP system being used, complete this table with the property or properties to be customized. For example,

  • to establish a Unicode connection between the SAP system and Talend Studio, you need to add the property jco.server.unicode and set its value to 1. Note that this property works if you are using SAP Java Connector 2.x and is unnecessary for SAP Java Connector 3.0 and higher versions.

  • to set up an SAP connection with Secure Network Communications (SNC), you need to add and set the following properties in this field.

    • jco.client.snc_mode
    • jco.client.snc_myname
    • jco.client.snc_lib=.../sapcrypto/sapcrypto.dll
    • jco.client.snc_partnername
    • jco.client.snc_qop
    Information noteNote: The values of the above properties vary with the system environment. Contact your SAP system administrator if you are not sure how to set the properties.

    For more information about setting the SNC parameters, see Configuring SNC: External Programs to AS ABAP Using RFC and Communication Paths that Support SNC.

This property is not visible when the Use an existing connection check box is selected.

SAP function extraction path

Select this option to specify a directory for the SAP function to generate files that hold the data extracted. You can enter the path to the directory in the text field to the right.

If this option is not selected, the files will be generated in the directory specified in the FTP directory field in the Basic settings view.

Because Talend Studio does not synchronize the directories specified by SAP function extraction path and FTP directory fields, make sure these two fields point to the same resource.

Information noteNote: This option is available only if you have installed the R2021-01 Studio Monthly update or a later one delivered by Talend. For more information, check with your administrator.
tStatCatcher Statistics

Select this check box to gather the Job processing metadata at the Job level as well as at each component level.

Global Variables

ERROR_MESSAGE

The error message generated by the component when an error occurs. This is an After variable and it returns a string.

Usage

Usage rule

The tELTSAPMap component is more commonly used along with the tELTSAPInput component. The name of the link from tELTSAPInput to tELTSAPMap should be same as the table name specified in the Default Table Name field of tELTSAPInput.

Support

tELTSAPMap should be used to interact with the ERP part of SAP, including S4/HANA.
