Configuring HTTP Streaming for SAP ABAP Table Reader Mappings in PowerCenter

Generating and Installing the ABAP Program in Stream Mode

Generating and Installing the ABAP Program in Stream Mode

To configure HTTP streaming for an ABAP table reader mapping, you must generate and install the ABAP program in stream mode.
  1. Create an SAP ABAP table reader mapping.
  2. In PowerCenter Mapping Designer, click
    Mappings
    Generate and Install R/3 Code
    .
    The
    Generate and Install
    dialog box appears.
  3. Enter the following information to connect to the SAP system:
    Property
    Description
    Connect String
    Required. DEST entry defined in the sapnwrfc.ini file for a connection to a specific SAP application server or for a connection that uses SAP load balancing.
    User Name
    Required. SAP source system connection user name. Must be a user for which you have created a source system connection.
    Password
    Required. Password for the user name.
    Client
    Required. SAP client number.
    Language
    Optional. Language for the mapping. Must be compatible with the PowerCenter Client code page. If you leave this option blank, PowerCenter uses the default language of the SAP system.
  4. Click
    Connect
    .
    A list of mappings in the folder appears. If the mappings are versioned, the version number appears next to each version of the mapping.
  5. Select the ABAP mapping for which you want to install ABAP.
    Use the following guidelines when you select the mapping for which you want to install ABAP:
    • You can install ABAP for all versions of a mapping.
    • You can install ABAP for different versions of the same mapping.
    • You can install ABAP for all versions of multiple mappings.
  6. Select the program mode as
    Stream
    .
  7. Optionally, select
    Enable Override
    to override the default ABAP program name.
  8. Optionally, select
    Use Namespace
    to prefix a namespace you registered with SAP to the ABAP program name.
  9. In the
    Development Class
    box, enter the name of the development class where you want to install the program.
    The default development class is $TMP.
    The $TMP development class is temporary. You cannot transport ABAP programs from this class to another system.
    Install ABAP programs that use a namespace in a development class that is in the same namespace.
  10. Click
    Direct Installation
    .
  11. Enter the ABAP program name if you selected
    Enable Override
    .
    This step also generates the ABAP program.
