Technical Description and Configuration
Information
Purpose
In addition to installing a SAP NetWeaver portal drive or a SAP NetWeaver portal as WebDAV clients, you have to make a number of settings in the cProjects or cFolders system. This section contains information about the configuration of the WebDAV interface in the cProjects or cFolders system and the configuration of a WebDAV repository manager in the portal.
Prerequisites
You have to configure the following data in the cProjects or cFolders system:
· You have to specify a server and a port for the HTTP protocol in the Internet Communication Manager. For more information, see SAP Library under Administration of the Internet Communication Manager.
· You have to set up the HTTP communication with the SAP system as the server (transaction SICF Maintain Services). For more information, see SAP Library under Components of SAP Communication Technology → Communication Between ABAP and Non-ABAP Technologies → Internet Communication Framework → Internet Communication Framework → Administration: HTTP Communication Using the SAP System → Administration: HTTP Communication Using the SAP System as a Server.
¡ The standard system contains the host cpro in the HTTP service tree in the default_host → sap entry. Activate the host cpro (WebDAV Interface for cProject Suite).
In the cross-client settings, for example, the timeout for the session is specified as being ten minutes in the cFolders and cProjects system. This means that a session in the cFolders or cProjects system is deleted if it has not been used for more than ten minutes.
For more information, see SAP Library under Activating an SICF Service.
¡ You use an external alias to make the settings for a particular client. Choose External Aliases and create a new alias for the cpro node. You can change the timeout predefined in the cpro host from the standard system.
If you enter a high value, there will be a large number of active sessions in the standard system, some of which may no longer be in use and this puts an unnecessary strain on the system performance.
If you enter a low value, the data that was buffered in a session is very quickly lost. For example, the WebDAV interface programs then have to read data from the database more frequently and this is detrimental to the system performance.
For more information, see SAP Library under Creating an Alias and Logging on to an SAP Web Application Server.
Process Flow
Executing IMG Activities in cProjects and cFolders
You make the system settings either in Customizing for cProjects or for cFolders. Call Customizing in the SAP Reference IMG as follows:
· cProjects
Choose Collaboration Projects → Documents → Settings for the WebDAV Interface.
· cFolders
Choose Collaboration Folders → Settings for the WebDAV Interface.
Carry out the following activities:
· Edit External IDs for the WebDAV Entry Objects (optional)
Objects that can be used as entry objects for the WebDAV interface are assigned a unique number (external ID). This number is part of the URL required for communication with the WebDAV application. Note the information in the Implementation Guide (IMG).
· Make Settings for the WebDAV Interface (mandatory)
In this IMG activity, you set up the communication between a WebDAV application and a cProjects and/or cFolders repository. The following data is part of the settings:
¡ WebDAV URL (mandatory):
You enter the WebDAV URL that is valid for the cProjects and cFolders repository according to predefined conventions. For more information about the WebDAV URL, see Defining the WebDAV URL and the Implementation Guide (IMG).
¡ Refresh time in seconds (optional)
The refresh
time specifies the maximum amount of time that lapses before the buffered data
is read again from the database.
If you do not enter a value for the
refresh time, the buffered data is not read again on a regular basis, but only
if an error occurs.
¡ Index service (only for cProjects, optional):
This setting is only relevant if you use Knowledge Management in the SAP NetWeaver Portal as a WebDAV application.
In the
standard process, a user only sees those projects below the entry object of
the cProjects structure in which he or she is participating and for which the
project work has not yet been completed.
For indexing (search function), a user is required who has read authorization
for all the projects below the
entry node. You specify this user here. In the portal, you have to map the
user who carries out indexing to the user you entered for the index service in
the cProjects system.
¡ Indicator for activating the WebDAV interface for cProjects or cFolders (mandatory)
Implementing Enhancement Spots (BAdIs)
There is a BAdI for both cProjects and cFolders that you use to influence the selection of data (attributes of the objects) before transferring the data to the WebDAV application. These BAdIs provide methods that you use to perform the following actions:
· Delete attributes that the standard system transfers to an object
· Change values of an attribute
· Add more attributes
For more information about creating enhancement implementations, see the Implementation Guide (IMG).
Configuring WebDAV Applications
WebDAV Repository Manager in SAP Knowledge Management
In order to have a cProjects or cFolders repository as a data source in the portal, you have to configure a WebDAV repository manager in the portal.
For more information, see Configuration of a WebDAV Repository Manager.
Portal Drive
The portal drive is a desktop application that must be installed and configured on each computer on which you want to use it. The user must have administrator rights on the computer on which you want to install the portal drive. Once the portal drive has been installed, the user does not need any administrator rights to use the software.
For more information, see SAP Library under Introduction to Using SAP Software → Working with Tools and Functions → Working with Documents and Folders → Working with Folders in Windows (Portal Drive).
