This guide describes the steps required to make existing Internet Transaction Server services (ITS services) – the Internet Application Components (IACs) – executable after migrating them into an SAP Web Application Server 6.40 with integrated ITS.

This situation occurs when you have developed your own IACs, which were executed up to now with a standalone ITS and which are now required to run on the SAP Web Application Server with integrated ITS.

Caution Caution

Note that the integrated ITS does not support Flow Logic and WebRFC applications. These must still be executed with a standalone ITS.

End of the caution.

Prerequisites

  1. You have migrated your SAP system, in which up to now the used IACs were executed, to an SAP Web Application Server 6.40.

  2. To better understand this document, we recommend that you familiarize with transaction SICF for creating Internet Communication Framework services in the SAP system.

  3. You must decide whether you additionally want to use the templates for the integrated ITS on a standalone ITS. If yes, you must pay attention that the desired changes are compatible.

    Note Note

    To facilitate compatible development in HTMLBusiness for integrated and standalone ITS, you can use the ITS switch ~icf. This switch is set to 1 for Web AS with integrated ITS.

    Example for using the switch in an HTML template:

    if (~icf==1)

    <Code for integrated ITS>

    else

    <Code for standalone ITS>

    end

    End of the note.

Procedure

To make an IAC executable with the integrated ITS, perform the following steps:

  1. Copying Existing Templates

  2. Setting Up the ICF Service for the ITS Service (IAC)

    • Create the ICF service name

    • Create ICF/ITS handlers

    • Activating ICF Services

  3. Maintaining ITS Service Parameters

  4. Changing HTML Templates

    • Adapt the URL generation in the HTML templates

    • ICF Alias Concept

    • ICF session ID handling

  5. Publishing the ITS Service

Result

As a result of this procedure, you can now run your ITS service directly with the integrated ITS.
