Static Pop Notes Vendors

If I am understanding you correctly you basically want the popup note to copy over to the document note instead of just displaying the one time popup?

That would require customization.

In the RowSelected(FieldSelecting may also work) event you could retrieve and set the warning. You can use the PXNoteAttribute.GetPopupNote method to get the note and then PXUIFieldAttribute.SetWarning method to set the note as a warning on the ASPX control. 

I would be careful that you don’t have any other warnings that need to be displayed on that field as the row selected(or field selecting events) will run frequently and possibly override other warnings. 

    public sealed class SOOrderExt : PXCacheExtension<SOOrder>
    {
        public static bool IsActive() => true;

        [PXBool]
        public bool? PopupShown { get; set; }
        public abstract class popupShown : BqlBool.Field<popupShown> { }
    }

    public class SOOrderEntryExt: PXGraphExtension<SOOrderEntry>
    {
        public static bool IsActive() => true;

        private string GetCustomerPopupNote(int customerID)
        {
            return PXNoteAttribute.GetPopupNote(Base.Caches[typeof(Customer).Name], Customer.PK.Find(Base, customerID));
        }

        private void SetPopupNoteWarning(string popupNote)
        {
            PXUIFieldAttribute.SetWarning<SOOrder.customerID>(Base.Document.Cache, Base.Document.Current, popupNote);
        }

        public void _(Events.FieldSelecting<SOOrder, SOOrder.customerID> e)
        {
            if(e.Row?.CustomerID is int customerID)
            {
                var orderExt = e.Row.GetExtension<SOOrderExt>();

                if (orderExt.PopupShown != true)
                {
                    orderExt.PopupShown = true;

                    var popupNote = GetCustomerPopupNote(customerID);

                    if (!string.IsNullOrEmpty(popupNote))
                    {
                        SetPopupNoteWarning(popupNote);
                    }
                }
            }   
        }
    }

Here’s a quick code sample. This is for Sales Orders and customer popup notes but could be adapted for vendors and Bills.

I created a cache extension SOOrderExt with a virtual field that just tracks whether or not the popup has been shown. In the SOOrderEntry graph I used the FieldSelecting event handler to show the popup if the CustomerID was not null and the virtual PopupShown field was not true(it will default to null when a record is loaded into the cache). I then am setting the PopupShown field to true to prevent the rest of the code from running again.

To get the Customer’s popup note I am using the GetPopupNote method and passing the Customer cache as well as the customer record(retrieved by the PK(Primary Key).Find method. And then to set the warning I’m using the PXUIFieldAttribute.SetWarning method and passing in the customer’s popup note.
