Research timer, which might help you periodically perform EXECUTE_QUERY in the demand block.

I don't think so (at least, I can't remember such a trigger).

However: how do you call the "demand" form? Suppose it is a WHEN-BUTTON-PRESSED trigger. Try with

-- call the "demand" form and enter a new record
call_form('demand_form');

-- the "demand" form has been closed and you're now back in the dashboard form. So - execute query and see what happens!
execute_query;

Yes, the When-Window-Activated (WWA) trigger executes. Therefore, you could simply execute the Execute_Query() built-in each time your WWA trigger fires.

If you want it to fire only when a new record has been added, then you could assign a value to a Global Variable in your DEMAND form and then look at this value in your WWA and only call the Execute_Query() built-in when it is a certain value. Make sure you reset the Global Variable after you call the Execute_Query() built-in. For example:

/* Sample When-Window-Activated trigger */
/* Code is untested...                  */
BEGIN
   IF ( NAME_IN('GLOBAL.DEMAND_INSERTED') = 'Y' ) THEN 
      :GLOBAL.DEMAND_INSERTED := 'N';
      Go_Block('YOUR DEMAND BLOCK');
      Execute_Query;
   END IF;
END;

Hope this helps,
