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 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.

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.

Node inputs

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.

Node outputs

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.


The Create Knowledge Center smart service is available as an expression function that can be executed inside a saveInto on a Interface Component or as part of a Web API.


a!createKnowledgeCenter( name, description, onSuccess, onError )


Keyword Type Description





The description of the new Knowledge Center.


Any Type

A list of saves or an HTTP response to execute after the smart service executes successfully. Created with a!save() or a!httpResponse(). When configuring this input, the fv!knowledgecenter function variable (KnowledgeCenter) is available to specify the knowledge center that was created. For more information, see Function Variables.


Any Type

A list of saves or an HTTP response to execute when the smart service does not execute successfully. Created with a!save() or a!httpResponse().

Feature compatibility

The table below lists this smart service's compatibility with various features in Appian.
Feature Compatibility Note

Can be used with Appian Portals if it is connected using an integration and web API.

Offline Mobile Incompatible
Sync-Time Custom Record Fields Incompatible
Real-Time Custom Record Fields Incompatible

Custom record fields that evaluate in real time must be configured using one or more Custom Field functions.

Old versions

There are older versions of this smart service. You can identify older versions by looking at the name to see if there is a version suffix. If you are using an old version, be sure to refer to the corresponding documentation from the list below.

Old Versions Reason for Update

The securityLevel has been removed in the Appian 18.1 release. Knowledge center security is managed completely by normal object security.

To use the latest version of the smart service node:

  1. Drag in a new Create Knowledge Center Smart Service node from the palette, and place it on the same connector as the current node.
  2. Configure the new node with settings matching your current, older node.
  3. Delete the old Create Knowledge Center Smart Service node.

To learn more about how Appian handles this kind of versioning, see the Function and Component Versions page.
