Set Expression

[upaliwije]

Hi Fiiends

I have the follwing pivit table in my QV doc.

My expression for the per claim cost is as follows

SUM({<LOSS_YEAR={"2013","2017"},PRL_PTY_CODE={'INP'},CLA_CODE={'SS'}>}$(vPaid))/COUNT(DISTINCT{<LOSS_YEAR={"2013","2017"},PRL_PTY_CODE={'INP'},CLA_CODE={'SS'}>} CLAIM_NO)

My requirement is to add another column to show the Per Claim Cost Increase % from 2013 to 2017 and show it in pivot table

The screen shot of new format shown below. Kindly advise how to fullfil my requirement.
