How To find issue Cancel Invoice

Hi @Rajginoya ,

Below Code includes a check to ensure that the Customer ID is not empty before invoking the Persist method:

public delegate void PersistDelegate();
[PXOverride]
public void Persist(Action del)
{
    if (Base.Document.Cache.GetStatus((object)Base.Document.Current) == PXEntryStatus.Inserted)
    {
        if (Base.Document.Current != null)
        {
            ARTran objARTran = Base.Transactions.Select().FirstTableItems.ToList().FirstOrDefault();
            if (objARTran != null)
            {
                SOOrder objSOOrder = SOOrder.PK.Find(Base, objARTran.SOOrderType, objARTran.SOOrderNbr);
                if (objSOOrder != null)
                {
                    SOOrderExt soOrderExt = objSOOrder.GetExtension<SOOrderExt>();
                    ARInvoiceExt invoiceExt = Base.Document.Current.GetExtension<ARInvoiceExt>();

                    // Check if Customer ID is not empty before copying data
                    if (!string.IsNullOrEmpty(objSOOrder.CustomerID))
                    {
                        invoiceExt.UsrCommentQuote = soOrderExt.UsrCommentQuote;
                        invoiceExt.UsrIntComment = soOrderExt.UsrIntComment;
                        invoiceExt.UsrPOComment = soOrderExt.UsrPOComment;
                    }
                    else
                    {
                        // Handle the case where Customer ID is empty, e.g., throw an exception or log an error.
                        // You may need to decide how to handle this situation based on your business logic.
                    }
                }
            }
        }
    }
    del();
}

I would try doing it in a RowPersisting event handler

        public virtual void _(Events.RowPersisting<ARInvoice> e, PXRowPersisting del)
        {
            ARInvoice invoice = (ARInvoice)e.Row;
            if (invoice != null && e.Cache.GetStatus(invoice) == PXEntryStatus.Inserted)
            {
                ARTran objARTran = Base.Transactions.Select().TopFirst;
                if (objARTran != null)
                {
                    SOOrder objSOOrder = SOOrder.PK.Find(Base, objARTran.SOOrderType, objARTran.SOOrderNbr);
                    if (objSOOrder != null)
                    {
                        SOOrderExt soOrderExt = objSOOrder.GetExtension<SOOrderExt>();
                        ARInvoiceExt invoiceExt = invoice.GetExtension<ARInvoiceExt>();
                        //should update current object as its persisting
                        invoiceExt.UsrCommentQuote = soOrderExt.UsrCommentQuote;
                        invoiceExt.UsrIntComment = soOrderExt.UsrIntComment;
                        invoiceExt.UsrPOComment = soOrderExt.UsrPOComment;
                    }
                }
            }

            del?.Invoke(e.Cache, e.Args);
        }
