Calculations and Values Display in webi report?

Hi,

I have two queries

1. I have created a webi report as below

But in Average and Max columns the values are coming two times.

i have used the calculations for Average and Max. Average = Average(Net Value) in (Org, Dist Channel), Max = Max(Net Value) in (Org, Dist Channel).

I need to show a report like below

How can i achieve this? is this possible to show Average, Max values without duplicates.

2. I need to remove Date and Net Value from the table because customer doesn't want to see these fields in a report. but if i remove this it is coming like below

for getting the correct results do i need to place Net value in Table?

Please help me
