Position in Expressin (Pivot)

[#1]

Hi at all,

my problem is a simple i think, so someone may help me...

I have a pivot table and in the last row i have an aggr() expression to get a total sum of Working hours.

The thing i want to know is how to place a value to another cell, ( the last cell as you can see on the picture), because QV places my sum arbitary.

Thanks for help...
