Set undefined value to variable

Hi all,

I have multiple variables in my qvw and I want to set a trigger which will set undefined value to all variable on opening the document.

Is there a way out to do so.

Thanks in anticipation.

Unfortunately you cannot do it unless you specify all the variables and set every one to your specified value.

You can do it in the script.

Hope it helps

Hi Neha,

If I understand the requirement in correct manner, U want to set all the varibles to predefined values.

If so, try to use the onopening from Document triggers.

variables are holding the last given values.
