Hi - 

  I have this piece of code in a method which I call in a forms print button click method. This button prints out 2 reports on the screen. 

My question is how can I disable the Dialogue box that pops up everytime I run COA report. I need to disable this parameter Pop up. 

I have tried controller.parmshowDialogue(false); It doesnt work in my case because Im calling the report directly from Menuitem and not using the controller. 

Can any one please assist me with this problem. 

Thanks
