Problem in refreshing parameter value

[Former Member]

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.

reward if helpful.

Hi Eric,

I checked in the debugging mode when i am pressing the back button, control is going to initialization event here parameter value is 00.After this selection screen is getting displayed and here parameter value is 10.Some memory involvement will be there for storing this parameter value.
