write a value from a report in a table-filed

Hello everyone ,

i have a problem.
I have designed a report, simmilar to the "Order Confirmation".
It´s the same design, only without prices (it´s a report for our production line).

Now I want to count up the amount of reports generated
(like the "No. Printed" on the form "posted sales shipment".
so i created a field in the tabel "Sales Header" with name "printed" (Integer)
After this i go to my customzed report in th "Copy Loop" section and added in the OnPostDataItem trigger this code:

"Sales Header".FIND;
"Sales Header".printed := "Sales Header".printed +1;
"Sales Header".VALIDATE(printed);

but nothing happes, when i start the report.
Tha value in the field "printed" on table "Sales Header" is still 0.

what´s my mistake ?


greetings,

Jan
