Creating Namespaces for Properties 
The WebDAV log allows you to add properties to a document. In these properties, you can save any data. A property is identified by a name and a namespace. In the Dav namespace, WebDAV specifies a range of default properties. These include, for example, the name of the creator, date when last modified, and the date of creation.
Besides the WebDAV properties, you can define other properties. The following properties can be added to documents in SAP Customer Relationship Management (SAP CRM):
Contained_In
This field contains the portal link to the business object that contains the document
KeyWords
Contains character strings that are marked for the business object that contains the document
You can change the namespace of these properties. Here you enter the same values as those maintained in the SAP NetWeaver Portal. You will find the properties to be entered in the portal. To do this, log on to the SAP NetWeaver Portal as portal administrator and choose .
To change the namespace for CRM properties, proceed as follows:
On the SAP Easy Access screen, choose .
In the field Database table enter CRMC_PRT_CUSTOM.
Choose Display.
Choose .
Check whether a line begins with the value WEBDAV_CUSTOM_NAMESPACE. If not, add the value.
For the entry WEBDAV_CUSTOM_NAMESPACE, enter the namespace you want.
Save your entries.
