SAP Portal KM Configuration
Application Area – Portal
Overview
KM (knowledge management) is a part of SAP Enterprise Portal. It is used to store and manage unstructured information form various data sources such as file system, intranet and World Wide Web.
Suppose we got below simple requirement. We have some technical materials for ABAP and Java and want to use KM to manage these materials. Two folder will be created for ABAP and Java. These materials need to be displayed in the portal and only authorized user can access these documents.
Configuration Detail
1. Create KM folders and upload needed documents
We plan to store these documents utilizing file system. Two folder need to be created under folder documents. In the navigation bar, go to Content Administration – > KM Content. Choose folder documents. Create two sub folder Java and ABAP.

Upload necessary documents into corresponding folders. The final structure is something like below:

2. Create iView for each KM folder
Go to Content Administration -> Portal Content. Choose one portal content folder to create iViews. In the iView template selection page, choose KM Navigation iView.

In the iView edit screen, change the property ‘Path to Initially Displayed Folder’ to the folder we just created.

Create a iVIew for ABAP folder as well.
3. Create WorkSet
Create a WorkSet to accommodate two custom iViews: Java and ABAP. Open the workset in edit mode and assign the iViews to it.

You have two options here. Delta Link means all futher on iViews will directly affected to the iViews in the workset. Copy means a copy of existing iView will be assigned to the workset. Any further change on the original iView will not affect the iView in the workset.

In this example, two iViews ABAP and Java are assigned to a WorkSet named Technical Documents.
4. Create Role
Create a new role named docRole in the Portal Content Studio and assign the workset to it. Remember to choose Yes for property Entry Point. Only entry point can be displayed in the portal navigation bar directly.

5. Assign Role to end user
Go to User Administration -> Identity Management, enter your user id and click Go button. Assign the new created role to your user account.
