Function

Validates the data processed through the Job into the connected server.

Purpose

Using a unique connection, this component commits a global transaction in one go instead of doing that on every row or every batch and thus provides gain in performance.

tSAPCommit Properties

Component family

Business/SAP

 

Basic settings

SAPConnection Component list

Select the tSAPConnection component in the list if more than one connection are planned for the current Job.

 

Release Connection

This check box is selected by default. It allows you to close the database connection once the commit is done. Clear this check box to continue to use the selected connection once the component has performed its task.

Warning

If you want to use a Row >Main connection to link tSAPCommit to your Job, your data will be committed row by row. In this case, do not select the Release connection check box or your connection will be closed before the end of your first row commit.

Advanced settings

tStatCatcher Statistics

Select this check box to collect log data at the 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.

Dynamic settings

Click the [+] button to add a row in the table and fill the Code field with a context variable to choose your SAP connection dynamically from multiple connections planned in your Job.

When a dynamic parameter is defined, the SAPConnection Component List box in the Basic settings view becomes unusable.

For examples on using dynamic parameters, see Scenario 3: Reading data from MySQL databases through context-based dynamic connections and Scenario: Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic settings and context variables, see Talend Studio User Guide.

Usage

This component is more commonly used with other tSAP* components, especially with the tSAPConnection and tSAPRollback components.

Limitation

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.
