today's date to be populated as the default value

You could use a Bound List with one entry (today's date):

Hello,

If you want to default the parameter to today's date, and also be able to manually change the parameter, you'll want to use a dashboard extender rule. This rule allows you to set parameters on dashboard load.

Create a new Dashboard Extender rule and find where it says Case Is = DashboardExtenderFunctionType.LoadDashboard. Below that replace "TestFunction" with your function name, change this loadDashboardTaskResult.ChangeCustomSubstVarsInDashboard to True, and add in the logic you would like to get today's date like below. YourParamName also needs to be replaced with the name of your dashboard parameter.

		Public Function Main(ByVal si As SessionInfo, ByVal globals As BRGlobals, ByVal api As Object, ByVal args As DashboardExtenderArgs) As Object
			Try
				Select Case args.FunctionType
					
					Case Is = DashboardExtenderFunctionType.LoadDashboard
						If args.FunctionName.XFEqualsIgnoreCase("YourFunctionName") Then 'Replace Name
							
							'Implement Load Dashboard logic here.
							
							If args.LoadDashboardTaskInfo.Reason = LoadDashboardReasonType.Initialize And args.LoadDashboardTaskInfo.Action =  LoadDashboardActionType.BeforeFirstGetParameters Then

								Dim loadDashboardTaskResult As New XFLoadDashboardTaskResult()
								loadDashboardTaskResult.ChangeCustomSubstVarsInDashboard = True 'Make sure it is set to True
								loadDashboardTaskResult.ModifiedCustomSubstVars = Nothing
								
								Dim TodaysDate As String = System.DateTime.Now.ToString 'Example logic, might need some formatting changes
								
								loadDashboardTaskResult.ModifiedCustomSubstVars.Add("YourParamName", TodaysDate) 'Update with your parameter

								
								Return loadDashboardTaskResult
								End If
						End If

Place your business rule in the highlighted area below

Place the rule on the main dashboard pane that is being ran.

Hi,

In the input parameter default value you can write a XFBR String function to call Dashboard XFBR rule and within that rule you can write a function to return the current date using VB.Net or C# functions.

This can solve the issue.
