How to add additional columns in RX-only: Applied Receipts Register R12?

Hi,

I have requirement in R12 to add the following additional columns in RX-only: Applied Receipts Register report.

Batch Total

Batch Amount Applied

Batch Amount Unapplied

Batch Amount Unidentified

Original Receipt Amount

Unapplied Receipt Amount

Invoice Amount

Unapplied Invoice Amount

I could not able to find some of the above column in the standard displayed columns in the designer attribute set.

How can we add the new columns to attribute set?

Appreciate your help on this.
