Running report from the OnModify trigger

bab · 2006-08-09

I have a problem, when running a report from the OnModify trigger of a table.
The situation is: when a record changes i need to send a notyfication e-mail. The attachment is a html file generated by a report.
When I run a report (SAVEASHTML) from the OnModify trigger, it seems, that the report runs the OnModify trigger of the table, and falls is recursion.
I tried it on several tables/reports.
Has anybody met this problem?

Nobody met this problem?
Other things: SQL2005, and NAV400 without any SP.

Hi bab

I just tried to save a report as htlm from the OnModify trigger and my computer locked up. It took my 5-10 minutes to kill Navision.

I don't know what is happening and I won't repeat the test

I guess we can conclude that we shouldn’t try to save reports as html from the OnModify trigger. Have you tried to solve the issue differently?

You could just send a email from the OnModify trigger and then link to the report or include the required information in the body of the email.

Regards

Yes, I think I will send a simple e-mail, but the reason was, why I tried to do this way, because if I send a report by mail, the SalesPerson doesn't need to login to navision.
Anybody else can solve this problem?

Create a function on sales line called skipsendingreport. In the function set a global variable DONNOTSENDREPORT to true.
Before running the modify(true) statement call the function.
In onmodify trigger run the report only if DONNOTSENDREPORT is set to false.

I tried it several times, it does not work.
My last try was:
ReportSended: Boolean (Global scope)
OnModifyRecord trigger of the form (SourceTable: T5050 (Contact)):
run the report if the ReportSended is FALSE, and set it TRUE.
And what i thought is impossible: it falls in recursion too. It seems, that the report runs this trigger too, and the "IF NOT ReportSended THEN" takes no effect... :?:

create a field then on the line and modify it to true once you've sent the email. Only send the email if field is checked false.

Maybe it works, but this is only a half solution: When will this field became FALSE?

hmm in your report you can do a modify without the true paramater.

I will try it, and post the result here.
thx

Finally it works :!:
Added a new Field in the T5050 (Contact) Notification Sent - Boolean
Created a report (Contact - Card), in the OnAfterGetRecord trigger:

"Notification Sent" := FALSE;
MODIFY;

Added a new function - NotifyByMail to the T5050:

Contact.RESET;
Contact.SETRANGE("No.", "No.");
FileName := ENVIRON('TEMP') + '\' + DELCHR(USERID, '=', ' ') + '.html';
IF FILE.EXISTS(FileName) THEN
  FILE.ERASE(FileName);
ContactCard.SETTABLEVIEW(Contact);
"Notification Sent" := TRUE;
ContactCard.SAVEASHTML(FileName);
SMTPMail.NewMessage('noreply@xx.xx', STRSUBSTNO(Text80000, USERID, "No."));
SMTPMail.SetWorkMode;
SMTPMail.SetHost(CompanyInfo."SMTP Server");
SMTPMail.AddLine(Text80001);
SMTPMail.SetToAdress(SalesRecSetup."Notify Email on Contact Change");
SMTPMail.AddAttachment(FileName);
SMTPMail.Send;
FILE.ERASE(FileName);

In the OnModify trigger of the table:

IF NOT "Notification Sent" THEN
  NotifyByMail;

Thanks all!
