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.

When a Job contains a parent Job and a 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

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.

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. When you create a Spark
Job, avoid the reserved word line when naming the
fields.

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.

Enter your RFC server details 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.

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.

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 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.

Enter your Kafka information in the fields
provided.

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

When the length of any string 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.

SAP Properties

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

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. 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.
