Hi @mrthanhkhoi 

You can try copying the note when you save the invoice:

// Extension of SOInvoiceEntry
// Example copying Description

protected void _(Events.RowPersisting<ARInvoice> e)
{
   var query = new SelectFrom<SOOrder>
      InnerJoin<SOInvoice>.On<SOInvoice.sOorderType.IsEqual<SOOrder.oderType>.
      And<SOInvoice.sOOrderNbr.IsEqual<SOOrder.orderNbr>>>
      Where<Use<SOInvoice.refNbr>.AsString.IsEqual<@P.AsString>>.
      View(Base);

   SOOrder so = query.Select(e.Row.RefNbr).TopFirst;

   so.OrderDesc = e.Row.DocDesc;

   Base.Cachesetypeof(SOOrder)].Update(so);
   if(Base.Cachesetypeof(SOOrder)].Updated.Cast<SOOrder>().Count() > 0)
   {
      Base.Cachesetypeof(SOOrder)].Persist(PXDBOperation.Update);                    
   }   
}

Hi @Leonardo Justiniano ,

Thank you very much for your answer.

I am a newbie for Acumatica so I don’t have much knowledge about this, I have a concern that why don’t we use event FieldUpdate? It should be more efficient than an event on Row (e.g: RowPersisting)

Regards,

Khoi

Hi @mrthanhkhoi 

FieldUpdated event is triggered when, indeed, a field value has changed. It is not a matter of efficiency. In my example I am saying that the description will be copied “only” when the invoice is saved. This way I  guarantee that I will have the last value specified by the user copied over.

I suggest you engage in the training courses provided by Acumatica where all these details are explained with really good examples and exercises
