Define Payment Predictor

Dear Group.

I am in process of implementing (enabling Payment Predictor in Peoplesoft 8.9) and i need some help in doing.

Currently we do have lock box process running but business users go in after the lockbox is processed they apply the payment mannully. We are trying to impleament the payment predictor to reduce the mannuel effort.

most of Our items have (symbol like '-' and '/' and 'space') it is very diffcult in doing matching the item to reference which recevie the lockbox as most part customer's ignore these symbols when they send the payments.

so i am requesting if any one have any good way of setting up the payment predictor. Looking for step by step document.
