Or is there way to customize PX.Objects.EP.NotificationGenerator?
Which is the graph which is used to perist CRSMEmail in NotificationGenerator.PersistMessages()

Hi @priekenberg40 

Not sure if it possible to override generic CreateNotificationProvider, but at least we can override SendNotification which calls CreateNotificationProvider.

public class ARInvoiceEntry_NotificationExt : PXGraphExtension<ARInvoiceEntry_ActivityDetailsExt, ARInvoiceEntry>
{
    >PXOverride]
    public virtual void SendNotification(string sourceType, string notifications, int? branchID, IDictionary<string, string> parameters, bool massProcess = false, IList<Guid?> attachments = null,
        Action<string, string, int?, IDictionary<string, string>, bool, IList<Guid?>> baseMethod = null)
    {
        baseMethod(sourceType, notifications, branchID, parameters, massProcess, attachments);
    }
}

Invoice PDF is created based on a report. So if you need to change some details inside PDF you would better change the report.

Thanks @taras, there is realy no good place to hook in custom code for manipulation the created invoice pdf (E-Invoice/ZUGFeRD).
I’ll do it this way for the time beeing:
 

    public class ARInvoiceEntry_NotificationExt : PXGraphExtension<ARInvoiceEntry_ActivityDetailsExt, ARInvoiceEntry>
    {
         PXOverride]
        public virtual void SendNotification(string sourceType, string notifications, int? branchID, IDictionary<string, string> parameters, bool massProcess = false, IList<Guid?> attachments = null,
            Action<string, string, int?, IDictionary<string, string>, bool, IList<Guid?>> baseMethod = null)
        {
            var activityExt = Base.GetExtension<ARInvoiceEntry_ActivityDetailsExt>();
            var sender = activityExt.CreateNotificationProvider<ARInvoice>(sourceType, notifications, branchID, parameters, attachments);

            var inv = Base.Cacheshtypeof(ARInvoice)]?.Current;
            if (inv != null)
            {
                List<FileInfo> _attachments = (List<FileInfo>) sender.GetType().BaseType 
                    .GetField("_newAttachments", BindingFlags.NonPublic | BindingFlags.Instance)
                    .GetValue(sender);
                foreach (FileInfo attm in _attachments)
                {
                   // manipulate pdf here
                }
            }
            if (!sender.Send().Any())
                throw new PXException(PX.Objects.CR.Messages.EmailNotificationError);
        }
    }

The problem is, that i have to bypass the overridden method completely and copy the code it contains to my method. Would be great if the non generic CreateNotificationProvider would have been called in SendNotification<TTemplateEntityType>. Then we could override it, but today it is not used at all.

@priekenberg40 I can see this line inside CreateNotificationProvider() 

var mainDocRecipient = GetPrimaryRecipientFromContext(NotificationUtility, sourceType, bAccount, source);

I hope override this method will help to omit copying

@taras, yes, but i do not get access to the generated report/attachment there.
