I am trying to do an expression to calculate the max of ( sum (Value) / sum (quantity) ) by supplier. This is not a problem when no selection has been made on supplier.
However, I want the max ( sum (Value) / sum (quantity) ) still to show the max value across all suppliers, even when a selection is made on a supplier
For example, in the below, the max ( sum (Value) / sum (quantity) ) is 350, from supplier JKL. If I selected DEF for example, I would still want the figure to show 350 (not 200)
Supplier ( sum (Value) / sum (quantity) )
I've tried various expressions but can't seem to get the max value to remain the same when I select a supplier.
Any help much appreciated!
