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

 

To enable communication between the application system (AS ABAP), whose information you manage with SAP NetWeaver ILM, and 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. Trigger transaction SM59 in the application system (AS ABAP).

  2. Choose   Edit  Create  .

  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:

    To avoid timeouts when there is a high volume of data, adjust the corresponding parameters for the HTTP connection as required.

    End of the note.
2. Activate HTTP connection to XML DAS for each client
  1. Call transaction SARA in each client of the application system.

  2. Choose Customizing.

  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

    1. Choose   Dispatcher  Services  HTTP Provider  Properties  .

    2. Select the parameter MaxRequestContentLength and adjust the value in the lower part of your screen.

  3. To optimize the parameter values that influence data transfer when there is a high volume of data, proceed as follows:

    1. Choose   Server  Services  HTTP Provider  Properties  .

    2. Select the following parameters and adjust the values in the lower part of your screen.
