Component family

Business/SAP

 

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.

Note that when a Job contains the parent Job and the child Job, the list displayed presents only the connection components in the same Job level.

 

Server Type

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

 

Client

Specify the SAP system client ID.

 

UserId and Password

Specify 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

Specify the language of the SAP system.

 

Host name

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

 

System number

Enter the system number.

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

 

System ID

Enter the system ID.

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

 

Group Name

Enter the group name.

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

 

Schema and Edit Schema

A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. The schema is either Built-In or stored remotely in the Repository.

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

  • View schema: choose this option to view the schema only.

  • Change to built-in property: choose this option to change the schema to Built-in for local changes.

  • Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion. If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the [Repository Content] window.

 

Table

Enter the name of the table from which the data will be retrieved.

 

Filter

Enter the filter condition between double quotes. The component will read data based on this condition.

Note that the column value must be surrounded by single quotes and there must be a blank space before and after the equals sign (=) in the filter expression. For example, "MANDT = '800' AND WAERK = 'EUR' OR (FKART = 'F2' AND VBELN = '0090038989')".

 

Start row number

Specify the sequence number of the row from which data retrieval starts. The sequence number of the row in an SAP table starts from 0.

The default value for this field is -1, which means to read all rows in the specified table.

 

Max row number

Specify the maximum number of rows to retrieve data from.

The default value for this field is -1, which means to retrieve all rows that meet the filter condition.

 

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 tSAP* 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.

Warning

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.

Advanced settings

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,

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

 

Set max length for variable length type when api.use_z_talend_read_table parameter is true

When the length of any sstring and string type field is set to 0 in SAP data dictionary, you need to select this check box and in the Max length field displayed specify the maximum length of the data to be retrieved for the sstring and string type fields. Note that:

  • This check box works only when the value of the SAP connection property api.use_z_talend_read_table is set to true.

  • This maximum length will be applied to all fields of sstring and string type. To avoid loss of data, you need to be very careful when determining its value.

 

tStatCatcher Statistics

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

Connections

Outgoing links (from this component to another):

Row: Main, Iterate

Trigger: On Subjob Ok, On Subjob Error, Run if, On Component Ok, On Component Error

Incoming links (from one component to this one):

Trigger: On Subjob Ok, On Subjob Error, Run if, On Component Ok, On Component Error

For further information about connections, see Talend Studio User Guide.

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. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

Usage

This component is usually used as a start component in a Job and it always needs an output link.

Limitation/ Prerequisites

Specific jar and dll files provided by SAP must be added to your Studio and the workstation hosting your Studio. The exact procedure varies among platforms such as 32-bit or 64-bit Windows or Linux. For more information, see the article How to install the SAP Java Connector on Talend Help Center (https://help.talend.com) and the Centralizing SAP metadata section in Talend Studio User Guide.
