Process designer elements


Process designer uses a combination of the default Business Process Model and Notation (BPMN) elements and BMC extended elements. For example, the Process designer uses Service Task element in BPMN to create Record, User Message, Expression, and Association elements. These elements are available in the palette of the Process designer UI. You can drag and drop the desired element on the canvas to design your process.

Note

Application business analysts can customize the objects developed in their own applications and that are marked customizable by the developers, but cannot customize the objects developed in com.bmc.arsys. For example, objects in core BMC applications like Foundation, Approval, and Assignment cannot be customized.

Some of the standard BPMN elements that BMC has used are described in the following table:

Element CategoryElement NameSymbolDescription
EventsStart Indicates where a process or sub-process starts.
EndIndicates the end of a process or sub-process.
Timer Interrupts a wait step and let the process make a decision about how to proceed after the wait step times out.
Error BoundaryCaptures errors and exceptions within a process and identifies the path that should be executed after the Business error or exception is captured. 
Error EndDisplays the business errors that occurs in a process.
Activities



Call ActivityCalls another process. It is for application integration and component reuse.
ConnectorIntegrates an application with third party systems.
User TaskRepresents user performing a task. The Task is represented by a record. The task is considered as complete if the completion criteria is satisfied.
Receive TaskRepresents a wait step in the process that waits for the arrival of a message.
Sub-Process

Describes a detailed sequence.

Service TaskModels a Service Task, which invokes a Java service method that is exposed as an Action Type through @Action annotation.
Web Request

Integrates an application with a RESTful web service in a codeless way.
GatewaysParallel

Models concurrency in a process. It forks into multiple paths of execution or joins multiple incoming paths of an execution.

Exclusive Models a decision in the process, and the conditions on exit paths.
Sequence FlowSequence FlowSequence element connects two elements in a process flow.
AnnotationsText Annotation    Provides additional information for the reader of the process diagram.

Service Tasks provided by BMC are described in the following table:

Element CategoryElement NameSymbolDescription
AssignmentSuggest AssigneeAutomates the task assignment by using machine learning.
CognitiveSuggest CategoryAutomates the manual task of data categorization by using machine learning.
PINVerify Pin

Verifies if the PIN value provided by a user matches the PIN value set for that user.

Records






Create RecordCreates a record instance for a specified record definition.
Delete RecordDeletes a record instance for a specified record definition.
Get RecordRetrieves a record instance for a specified record definition.
Get Records by QueryRetrieves a set of record instances based on a specified query.
 Get Security Label

Retrieves a security label for a specified record definition.

Remove Security Label

Deletes a security label for a specified record definition.

To identify if the security label is updated, see Identifying updates to the security label.

Update RecordUpdates a record instance for a specified record definition.
Set Security Label

Restricts access of a user, group, or a role to a record.

To identify if the security label is updated, see Identifying updates to the security label.

User Message

Send MessageSends a notification about the status of a particular activity.
Send Message by TemplateYou can use the existing templates to send notifications.
Show AlertUsed to display an error, warning, note.
Associations

Associate Child RecordsUsed to associate a child record instance with its parent record instance.
Associate Records Used to associate the two record instances with the relevant ids.
Disassociate Records

Removes the association between the two records.
Disassociate All Records

Removes the association between all the records.
DocumentCreate Document

Accesses individual attributes within the document schema
ExpressionsCompute ValueUsed in the workflow to calculate a value by performing an arithmetic operation.
Data StreamingPublish Event

Stores the application event data that is used to derive usage metrics for the application.

Example of using Process designer elements

Consider a purchase process as an example. The purchase process involves a manager review to initiate a procurement process. If the item is available, it is shipped to the customer and a notification is sent to the customer. If the item is not available, the order is canceled and the customer is informed about the cancellation.

A purchase process is shown in the following flowchart:

The purchase process can be designed in Process designer using elements available in the palette of the Process designer UI. The following image illustrates the purchase process designed using Process designer:

The following table describes the various elements used in the purchase process:

No.Element TypeDescription
1Start EventDenotes the starting of a process
2User TaskManager review requires a human intervention. Hence, a user task element is used here.
3Sub ProcessAfter the manager review is complete, and the completion criteria is fulfilled, a procurement process is triggered. Since procurement is a larger process in itself, a Call Activity element is used here.
4Exclusive GatewayDepending on the availability of the item, the process progresses further. For a decision to be taken and further direct the process to an appropriate activity, an exclusive gateway is used.
5Parallel GatewayIf the item is available, the shipment activity has to be triggered and also the customer has to be informed about the shipment. Both these activities must happen concurrently, so a parallel gateway is used.
5aUser MessageThe customer has to be notified about the shipment date, a User Message Service Task is used.
5bUser TaskShipping an item needs human intervention. Hence, a user task element is used.
6Parallel GatewayThe end result of shipping an item and informing the customer should converge for the process to end. The parallel gateway is used is join the two paths of execution.
7User MessageIf the item is not available the customer has to be informed about non availability. A user message element is used to trigger this notification.
8Update RecordIf the item is not available the order has to be canceled. Update record element is used process the cancellation activity by setting the Status field of the record to Cancel.
9Delete RecordAfter the order has been canceled, it must be deleted. A delete record element is used to delete the order.
10End EventDenotes the completion of a process.
