After-Report trigger

Hi all,

In after report trigger i gave the message as
srw.message(100,'the file '|| :desname ||' created successfully).

If i run the report in the report builder it gives me the message after the report is run.

But if i call the same report from the form with the run_product.the report runs correctly but this time i do not get the message.Why???What i am doing wrong.I am not able to find out.PLs help if any body knows the solution.

I am writing the report o/p to the file and it is creating successfully in both the case.

Thanks in advance
pras
