How to Programmatically Open/Close Financial Period

Hi Team

We have a requirement where on payment save we have to programmatically open the financial periods, if closed. I have tried to Implement logic in ARPaymentEntry graph on Save but it is not working as expected, can you help please to achieve this.

public delegate void PersistDelegate();
        [PXOverride]
        public void Persist(PersistDelegate del)
        {
            if (Base.Document.Current != null/* && Base.IsImport == true*/)
            {

                FinPeriodStatusProcess finPeriodStatusProcess = PXGraph.CreateInstance<FinPeriodStatusProcess>();
                finPeriodStatusProcess.Filter.Current.Action = FinPeriodStatusProcessParameters.action.Open;
                finPeriodStatusProcess.Filter.Current.FromYear = "2024";
                finPeriodStatusProcess.Filter.Current.ToYear = "2024";

                string month = "202404";
                string year = "2024";
                FinPeriod masterFinPeriod = PXSelect<FinPeriod, Where<FinPeriod.finPeriodID, Equal<Required<FinPeriod.finPeriodID>>,
                                                  And<FinPeriod.finYear, Equal<Required<FinPeriod.finYear>>>>>.Select(Base, month, year);
                finPeriodStatusProcess.FinPeriods.Current = masterFinPeriod;

                masterFinPeriod.Selected = true;
               // masterFinPeriod.Closed = true;
                masterFinPeriod.Status = "Open";
                finPeriodStatusProcess.FinPeriods.Update(masterFinPeriod);

                finPeriodStatusProcess.Actions["Process"].Press();
            }
            del();
        }

Thank you In Advance.
