Tasks

Rename the diagram into "Request management" by clicking in the blank space around the pool

Rename the pool into "Leave request management"

Rename the lane into "Manager"

Rename the start event into "New leave request"

Since the submission of a new leave request happens at pool level (process instantiation), no need for a Submit request task ; just rename the default human task into "Validate request"

Add a terminate end event that you can rename "Happy end"

Go to the Development > Business Data Model > Manage menu option

Add a business object named LeaveRequest (with an upper case "L"), with 4 attributes:

Click Finish

In the Execution pane > Contract tab, click on Add from data…​ to generate the contract inputs from the business variable

Choose the Business variable option, and then the leaveRequest variable

Click Next

Unselect requesterName and status as the process doesn’t need this information from the form to instantiate
The default values of business data attributes mapped to contract inputs are automatically set thanks to a script generated along with the contract inputs themselves.

Click Finish, carefully read the warnings, and press OK and OK.

In the Execution pane > Contract tab, a complex contract input is created, mapped to the selected attributes of the leaveRequest business variable, as shown here:

Go back to the Data pane, Pool variables tab, Business variables table

Click on leaveRequest and on the Edit…​ button

Close to the Default value field, click on the pencil icon

In the script, add: leaveRequestVar.status = "submitted", and

def initiator = BonitaUsers.getProcessInstanceInitiator(apiAccessor,processInstanceId);
leaveRequestVar.requesterName = "$initiator.firstName $initiator.lastName"

def leaveRequestVar = new com.company.model.LeaveRequest()
leaveRequestVar.startDate = leaveRequestInput.startDate
leaveRequestVar.endDate = leaveRequestInput.endDate
leaveRequestVar.status = "submitted"
def initiator = BonitaUsers.getProcessInstanceInitiator(apiAccessor,processInstanceId);
leaveRequestVar.requesterName = "$initiator.firstName $initiator.lastName"
return leaveRequestVar

Click OK, and OK.
