Absence Quota Deduction

Hi,

What I need to do is when I enter absence I don't want to deduct the off days of the quota.

for example if I have enter an absence from 25.05.2016 to 28.05.2016 it deduct 4 days of the quota.

But I want to deduct only 2 days because 27&28 are off days (Not working days).

This is what I did in the counting rule

When I enter absence from 25.05.2016 to 28.05.2016 as the following it deduct 4 days (Quota Days). and I want to deduct 2 days since Friday and Saturday are day off
