There is no functionality in Qlikview to use the one object data in to another object but Qlikview would allow you copy the expression from one chart to another chart. You should have arrived at this 333.754 with help of some expression.
You can use the same expression in to another char and you can do the calculation.
But to get this 333.754, you need to use "Total" Modifier in you exprssion or Aggr() function.
For Example, Your expression to get 33.754 is = Sum(Gross) in Object 1.
Now to use this 333.754 in other chart, you need to tweak your expression like Sum(Total<ID> Gross).
Hope this helps you.
Thank you for your reply. The code you suggested is working only if you want to sum
something depending on a simple sum or count. However if you would like to calculate
something covering multiple dimensions this won't work.
What I would like to do is to mutiply Price*Amount for every ID and the total sum of this
as shown in the table (which is 333.754). Any thoughts on how to do this?
