PXProcessing SetError not showing in UI Grid

Question

This my process screen: as you can see it throws errors but it doesnt indicate the error mark on the grid. After clicking the process button, it just unchecks the checkbox in my records

i want the grid to be like this(with the red 'x' mark):

this is my graph :

public PXCancel<PayrollFilter> Cancel;

    public PXSetup<PayrollSetup> PayrollSetup;

    public PXFilter<PayrollFilter> Filter;

    [PXFilterable]
    public PXFilteredProcessingJoin<PayrollEmployeeProcess, PayrollFilter,
                                InnerJoin<EPEmployee,
                                    On<PayrollEmployee.employeeID, Equal<EPEmployee.bAccountID>>,
                                InnerJoin<Branch,
                                     On<EPEmployee.parentBAccountID, Equal<Branch.bAccountID>>>>,
                                Where<PayrollEmployee.payPeriodID, Equal<Current<PayrollFilter.payPeriodID>>,
                                And<Branch.branchID, Equal<Current<AccessInfo.branchID>>>>> EmployeePayrollProcess;



    #region Constructor
    public PayrollProcess()
    {
        PayrollSetup setup = PayrollSetup.Current;

        EmployeePayrollProcess.SetSelected<PayrollEmployeeProcess.selected>();

        EmployeePayrollProcess.SetProcessDelegate(delegate (List<PayrollEmployeeProcess> employees)
        {
            if (Filter.Current == null) return;

            var payPeriod = Filter.Current.PayPeriodID ?? 0;
            var payrollPeriod = Filter.Current.PayrollPeriodID ?? 0;

            if (payPeriod == 0 || payrollPeriod == 0) return;

            PXLongOperation.StartOperation(this, delegate ()
            {
                bool errorOccured = false;
                foreach (PayrollEmployeeProcess employee in employees)
                {

                    PayrollRegisterEntry graph = PXGraph.CreateInstance<PayrollRegisterEntry>();
                    try
                    {

                        graph.ProcessPayroll(employee, payPeriod, payrollPeriod);
                        PXProcessing<PayrollEmployeeProcess>.SetInfo("Employee processed");

                    }
                    catch (Exception ex)
                    {
                        errorOccured = true;
                        //employees.IndexOf(employee), 
                        PXProcessing<PayrollEmployeeProcess>.SetError(ex);
                    }
                    finally
                    {
                        graph.Clear();
                    }
                }
                if (errorOccured) throw new PXException("At least one employee was not processed.");
            });

        });
        // EmployeePayrollProcess.
    }`

can anyone can help me? I'm using Acumatica 6

Throwing an exception in Acumatica sets the error in the header. To set a Row or Field level error you need to set/raise it. There's a few ways to set/raise errors, what they have in common is that they don't use the 'throw' keyword.

For a processing screen with a filter, use the following syntax to raise the error:

PXFilteredProcessing<GridDetailDAC, GridFilterDAC>.SetError(rowIndex, new PXSetPropertyException("Error Message", PXErrorLevel.RowError));

Processing screen without filter:

PXProcessing.SetError(rowIndex, new PXException("Error Message"));
