In this scenario, an one-single-component Job uses the tSAPIDocInput component to keep listening to the creation of IDoc files in a given SAP R/3 system.

To replicate this scenario, you need to:

  1. Create an RFC Destination on the given SAP R/3 system.

  2. Configure tSAPIDocInput to listen to the invocation from this SAP R/3 system.

Creating an RFC Destination for the listener component tSAPIDocInput

Logon to a given SAP R/3 system and then proceed as follows to create the required RFC Destination:

  1. Execute the transaction SM59 to open the Display and maintain RFC destinations view.

  2. In this view, select the TCP/IP connections option and click Create.

    Then the RFC Destination view displays.

  3. In RFC destination field of this view, type in the name of this RFC Destination to be used. As this field is case-sensitive, it is recommended to use upper case characters. In this example, we name it as IDOC_TALEND.

  4. In the Connection type field, select the T type meaning to start an external program via TCP/IP.

  5. In the Description field, type in a short text to describe this RFC Destination being created. In this example, we enter simply TALEND IDOC LISTENER.

  6. In the Logon area, select the Current user check box and then click the Save button on the top toolbar.

    Then the RFC Destination IDOC_TALEND view is opened.

  7. In this view, click Registration to display the Program ID field and type in the program ID. This program ID must use the same name as this created RFC Destination, that is, IDOC_TALEND. Then again, click the save button on the top toolbar to validate this configuration.

  8. Still on the top toolbar, click the back button several times to go back to the SAP Easy Access view (SAP main screen) and execute the transaction SMGW to open the gateway monitor view.

  9. From the menu bar of the gateway monitor view, select Goto > Parameters > Display. Then an table like the following one displays, where you can find the gateway service of this given SAP R/3 system.

In this example, the gateway service to be used is sapgw00.

Now, the required RFC Destination has been created.

Configuring the listener component tSAPIDocInput

In the Integration perspective of your Studio, proceed as follows:.

  1. Drop the tSAPIDocInput component from the Palette onto the design workspace.

  2. Double-click this component to open its Component view.

  3. In the Client field, type in the client number of this given SAP R/3 system. In this scenario, it is 000..

  4. In the Userid and Password fields, type in the authentication information in the corresponding field.

  5. In the Language field, type in the language used by this given SAP R/3 system. In this example, it is EN.

  6. In the Host name field, type in the IP address of the hosting server of this given SAP R/3 system.

  7. In the System number field, type in the system number of this given SAP R/3 system.

  8. In the Gateway service field, type in the used gateway service name.

  9. In the Program ID field, type in the program ID you have defined when creating the required RFC Destination. In this example, it is IDOC_TALEND.

  10. In the XML-IDoc file output field, enter the path or browse to the location where you need to store the received SAP IDoc file.

Job execution

  1. Press CTRL+S to save your Job and press F6 to run it.

    From this console, you can read that the tSAPIDocInput component is listening to this given SAP R/3 system.

  2. Back to the created RFC Destination in this SAP R/3 system, click Test connection.

The test result indicates that the connection between this given SAP R/3 system and the listener component tSAPIDocInput component succeeds.

Now the tSAPIDocInput component is listening to your SAP R/3 system and wait for the invocation of the previously defined RFC Destination.
