Property Type

Select the way the connection details
will be set.

• Built-In: The connection details will be set
  locally for this component. You need to specify the values for all
  related connection properties manually.

• Repository: The connection details stored
  centrally in Repository > Metadata will be reused by this component. You need to click
  the […] button next to it and in the pop-up
  Repository Content dialog box, select the
  connection details to be reused, and all related connection
  properties will be automatically filled in.

Use an existing connection

Select this check box and from the Connection configuration drop-down list displayed, select the component
in which the relevant reused database connection is configured.

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.

• Built-In: You create and store the schema locally for this component
  only.

• Repository: You have already created the schema and stored it in the
  Repository. You can reuse it in various projects and Job designs.

• 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.

This
component offers the advantage of the dynamic schema feature. This allows you to
retrieve unknown columns from source files or to copy batches of columns from a source
without mapping each column individually. For further information about dynamic schemas,
see
Talend Studio

User Guide.

This
dynamic schema feature is designed for the purpose of retrieving unknown columns of a
table and is recommended to be used for this purpose only; it is not recommended for the
use of creating tables.

Name

Enter the name of the Data Store Object from which data will be retrieved.

Max row number

Specify the maximum number of rows to be retrieved. By default,
the value is set to -1, which means all rows will be
retrieved.

Filter Group

Specify the search condition(s) used to filter
data to be retrieved by clicking the [+] button to
add as many rows as needed, each row for a search condition, and set the
value of the following attributes for each condition.

• Column: enter the name of the schema column
  based on which retrieved data will be filtered.

• Sign: select either
  Include or Exclude
  from the drop-down list.

  • Include: the data that meets the
    condition will be retrieved.

  • Exclude: the data that doesn’t meet
    the condition will be retrieved.

• Operator: select from the drop-down list the
  data filter operator used to build the search condition.

• Value: specify the search value used to build
  the search condition.

• High value: specify another search value used
  to build the search condition for the between operator.

  When using a column of Date type to specify a filter, the date and
  time values in the Value and High
  Value columns should be in the format
  yyyyMMdd and
  HHMMSS, which might be different from the
  format defined in the schema editor.

The following wildcard characters can
be used when specifying the search value using pattern:

• *: match any number of characters.

• +: match a single character.

• #: be used to escape characters (e.g. *, #)
  and for exact case sensitive comparison.

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.

Use FTP-Batch Options

Select this check box when the size of data to be retrieved is larger than
the size specified in the Fetch size field. With this
check box selected, the SAP system will generate as many files as needed and
write the retrieved data into these files, and this component will then read
the files via an FTP connection to retrieve data and transfer the retrieved
data to the output component.

The following properties need to be specified when this checkbox is
selected:

• File Protocol: Select FTP or the secure
  alternative SFTP.

• Host: The IP address or host name of the FTP
  server.

• Port: The listening port number of the FTP
  server.

• User and Password: The
  user authentication data required to access the FTP server.

• Directory: The directory where the files
  generated by the SAP system will be saved.

• Data filename prefix: The prefix of the files
  generated by the SAP system.

Fetch size

Enter the fetch size (in KB) that specifies the amount of
resultset data sent during one single communication step with the SAP BW
database.

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.

ERROR_MESSAGE

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

Usage rule

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

Limitation

Currently only the fields of the DSO itself can be extracted.
The extraction of navigation attributes is not supported.
