Parallel Gateway

Overview

A parallel gateway is a control structure used to create parallel branches and merge parallel paths in business processes. It ensures that all branch paths execute in parallel rather than sequentially. Parallel gateways are typically used to represent parallel tasks or activities in a workflow.

Data Table

Data table structure is as follows:

Field	Type	Description
user	User Selection	Leave Applicant
leaveType	List Selection	Leave type, options include: Annual Leave, Sick Leave, Personal Leave, Compensatory Time Off
startDate	Date	Leave start time
endDate	Date	Leave end time
reason	Multi-line Text	Leave reason
durations	Function	Number of leave days. Configuration content: DATE(endDate) - DATE(startDate) + 1

durations configuration content:

DATE(endDate) - DATE(startDate) + 1

Workflow Configuration

The first parallel gateway distributes tasks to both Department Head and HRD simultaneously after supervisor approval. The second parallel gateway waits for both Department Head Approval and HRD Approval to be completed before the workflow ends.

Global Settings

Add startup form for initiator to fill in application information.

Supervisor Approval Node

Configure handler as supervisor role

Loop Collection Configuration:

Completion Condition Configuration:

Operation Settings

// Permission Expression
${task.endTime != null || task.assignee != user.id}

Department Head Node

Loop Collection Configuration:

Completion Condition Configuration:

Operation Settings

// Permission Expression
${task.endTime != null || task.assignee != user.id}

HRD Approval Node

// Permission Expression
${task.endTime != null || task.assignee != user.id}

Parallel Gateway

Gateway functionality is determined by gateway type, no configuration needed. Reference Documentation
