Problem in refreshing parameter value

Former Member — Thu, 20 Mar 2008 08:01:15 GMT

Hi Friends,

I am executing a report and entering some data like 10 in the parameter field. executing it. output displayed. Now I am pressing back button and it is returning back to selection screen. Here 10 is by default in parameter field. I think some memory involvement is there to store this 10. Requirement is that when i press back button and the control return to the selection screen, parameter value should be blank.

Hi,

Use Event AT-SELECTION-SCREEN OUTPUT.

In this event initialize your parameter field.

Hope this helps.
