AR_ADJUSTMENTS Reversal question

A transaction has an Adjustment and that Adjustment is reversed. How to link this reversal to the adjustments in AR_ADJUSTMENTS_ALL table? To simplify this with an example : 
Transaction Number 1234 had an Adjustment # 234 for $10 and then there was a reversal to the Adjustment # 234, how do I relate this Adjustment Reversal to the Original Adjustment in AR_ADJUSTMENT_ALL

Any help will be appreciated.

Thanks,
