Create Knowledge Center Smart Service


A knowledge center is a second-level container in Appian Document Management (below Communities). All folders and files are stored in knowledge centers. By creating knowledge centers and granting access to other users, you can share files and collaborate on them, either within a process, or through a portal page.

The Create KC smart service node allows you to create a knowledge center and configure the User Permission Levels from a process.

Configuration Options

This section contains tab configuration details specific to this smart service. For more information about common configurations see the Process Node Properties page.

Data Tab

This tab displays all the Node Inputs and Node Outputs for the Service Node. You can add additional inputs and outputs, if needed. The default inputs are:

Input Type Required Multiple
Knowledge Center Name Text Yes No
Knowledge Center Description Text No No

If the node is run without being assigned to a user (or a group) you must specify values for each of the Node Inputs listed in the table above. You can either manually enter data into the text-field, or a value can be generated using the using the Expression Editor. When using the Expression Editor, you can reference and modify Process Variables, rules, constants, and other data. The expressions then specify your Node Input values.

If the node is assigned, the Node Input values are collected from a form.

To retain the ID of the KC for use elsewhere in the Process Model:

  1. Click the Outputs property sheet.
  2. Select The created knowledge center. The Result Properties are displayed.
  3. Create a Process Variable or select an existing PV (with a Knowledge Center data type) from the Target list.
