Create Knowledge Center Smart Service (17.4)

This page contains information related to an old version of the Create Knowledge Center Smart Service.

To take advantage of the latest features and improvements, we always recommend you use the latest version whenever possible. See the latest version's page for information about what's been changed.


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 its security 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.

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
Parent Community Collaboration Community No No
Knowledge Center Name Text Yes No
Knowledge Center Description Text No No
Security Level (Deprecated) Number Yes 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.
