Change Management System instance has configuration details necessary to connect to specific Change Management System. This is used to query Change Tickets, and optionally create Change Ticket or Incidents. This is used during project deployment executions. Each instance is defined with unique name and code, and in addition has underlying system specific properties for connection.

To create a Change Management instance, select the Change Management tab, and click the + button. To edit an existing instance, click on an Instance row from the list.

Click the Test  button to test the connection and verify that the url, port, username, and password are correct. Click the Save button to save the changes. Optionally click the Apply button to save the changes, but remain on the current screen until the Cancel button is clicked.

ServiceNow Properties

Property

Type

Description

ServiceNow URL

String

The URL for accessing ServiceNow.

ServiceNow User Name

String

A local ServiceNow service account user with a non-expiring password. 

ServiceNow Password

String

The password for the ServiceNow User Name above.

Note that encrypted properties are stored in Credential Store (Local or External) and can be configured using Edit button next to credential name drop down. Alternatively, you can reuse single credential for multiple properties also, in which case you should name that credential appropriately.

Required for the following Auth Types, BasicAuth and  OAuthResourceOwner

ServiceNow Auth Type

String

Authentication method for connecting to ServiceNow, BasicAuth,  OAuthResourceOwner, OAuthJWTAssertion.  Defaults to BasicAuth.  

ServiceNow Client ID

String

The auto-generated unique ID of the application. The instance uses the client ID when requesting an access token. 

Required for the following Auth Types, OAuthResourceOwner and OAuthJWTAssertion.

ServiceNow Client Secret

String

The shared secret string that both the instance and the client application use to authorize communications with one another. The instance uses the client secret when requesting an access token. (Encrypted).  

Required for the following Auth Types, OAuthResourceOwner and OAuthJWTAssertion.

ServiceNow Keystore Path

ServiceNow Refresh Token Lifespan

Long

The number of seconds that a refresh token is valid. The instance uses the lifespan value when requesting a refresh token. By default, refresh tokens expire in 100 days (8640000 seconds).

ServiceNow Request GET URL

String

The URL to get the change request details as json response. 

  • Default URL is /api/now/table/change_request?sysparm_query=number%3D{SN_CHANGE_NUMBER}

  • If needed, you can change and use your custom GET url for ServiceNow REST endpoint.  The URL should include {SN_CHANGE_NUMBER} string as the execution system will replace it with the actual change number during execution.

    • e.g. /api/xyz/mycompanty_servicenow_generic_api/readChangeRequest?number%3{SN_CHANGE_NUMBER}

  • If the response returned from this GET API contains an attribute called description it will be mapped to the description of the linked ticket, otherwise the description on the links tab will appear as empty.  Prior to 5.5.0.2, an error would occur if the description field was not present in the payload returned from this GET API.

ServiceNow Navigation Request URL

String

The URL to open ServiceNow and navigate to the Change ticket associated to the project workflow execution

ServiceNow Request POST URL

String

The URL to create a change request.

  • Default URL is /api/now/table/change_request

  • If needed, you can change and use your custom url to create a new change using the POST operation

    • if you want to use Service Catalog, then change the url to /api/now/table/sc_request

Approved Check Script

String

A Groovy expressions which determines whether a task for the change ticket is approved or not.  The expression must return a boolean, and has access to the following variables:

  • TICKET - an object with fields (JSON) contained in the change ticket, as returned by the ServiceNow REST API.  Fields are referenced as TICKET.<field name>.<sub-field name>

  • FD_ENVIRONMENT_CODE - The environment for a particular deployment request or associated pipeline stage.

Info

If the Approved Check Script is left blank, the default implementation is to return true if the "approval" field of the ticket is set to "approved".

Simple Example which is used by default
Code Block
languagegroovy
TICKET.approval == 'approved'
Example that checks myfield value specific to target environment
Code Block
languagegroovy
(TICKET.myfield == 'UATApproved' && FD_ENVIRONMENT_CODE='UAT') || (TICKET.myfield == 'PRODApproved' && FD_ENVIRONMENT_CODE='PROD')
Tip

If you want to see values that can be used, enable FINEST log level for flexagon.fd.model.integration.cms.CMSScript using Admin Operations.

Following example is to check if current date time is between start_date and end_date defined on Ticket. Let's assume format for the date string returned and TimeZone as GMT.

Check if now is between start_date and end_date defined on ticket
Code Block
languagegroovy
import java.util.Date;
import java.util.TimeZone;
import flexagon.ff.common.core.utils.FlexDateTimeUtils;

if(TICKET.approval == 'approved' && TICKET.start_date != null && TICKET.end_date != null)
{
    Date start = FlexDateTimeUtils.stringToDate(TICKET.start_date, "yyyy-MM-dd HH:mm:ss", TimeZone.getTimeZone("GMT"));
    Date end = FlexDateTimeUtils.stringToDate(TICKET.end_date, "yyyy-MM-dd HH:mm:ss", TimeZone.getTimeZone("GMT"));
    Date now = new Date();
    if(now.after(start) && now.before(end))
    {
      return true;
    }
}
return false;

Rejected Check Script

String

A Groovy expressions which determines whether a task for a change ticket is rejected or not.  The expression must return a boolean, and as has access to the following variables:

  • TICKET - an object with fields (JSON) contained in the change ticket, as returned by the ServiceNow REST API.  Fields are referenced as TICKET.<field name>.<sub-field name>

  • FD_ENVIRONMENT_CODE - The environment for a particular deployment request or associated pipeline stage.

Info

If the Rejected Check Script is left blank, the default implementation is to return true if the "approval" field of the ticket is set to "rejected".

Simple Example which is used by default
Code Block
languagegroovy
TICKET.approval == 'rejected'
Example that checks myfield value specific to target environment
Code Block
languagegroovy
(TICKET.myfield == 'UATRejected' && FD_ENVIRONMENT_CODE='UAT') || (TICKET.myfield == 'PRODRejected' && FD_ENVIRONMENT_CODE='PROD')

Additional Info Script

String

A Groovy expression which determines additional information to add to an external approval when it is approved or rejected.  The expression must return a Map<String, String> and have an entry with the key of "notes" for the value to get added to external approval as a task note. Script has access to the following variables:

  • TICKET - an object with fields (JSON) contained in the change ticket, as returned by the ServiceNow REST API.  Fields are referenced as TICKET.<field name>.<sub-field name>

  • FD_ENVIRONMENT_CODE - The environment for a particular deployment request or associated pipeline stage.
