Procedure documentationEstablishing an HTTP Connection from the Application System to XML DAS

 

To enable communication between the application system, whose data you manage with SAP NetWeaver ILM, and the XML Data Archiving Service (XML DAS) , you need to establish an HTTP connection.

You need to activate this system-wide HTTP connection in each client of the application system from which you want to archive data using XML DAS. In this way, in addition to storing the archive files, you can also store references to the related documents that were stored with ArchiveLink.

You can also adjust the parameter values of the HTTP provider as required.

Procedure

1. Creating the HTTP Connection to XML DAS

  1. In the application system (AS ABAP), start transaction SM59.

  2. Choose Start of the navigation path Edit Next navigation step Create End of the navigation path.

  3. Enter the following general data:

    • RFC Destination: Name of the HTTP connection

    • Connection Type: G (HTTP connection to external server)

  4. Define the HTTP connection as follows:

  3. Under Cross-Archiving-Object Customizing, choose Technical Settings.

  4. Under HTTP Connection to XML DAS for WebDAV Store, enter the name of the HTTP connection.

Optional: Adjust parameter values of the HTTP provider
