Summary

customer overpayments and under payments needs to be settled to full amount

Hi experts,

 

I am searching for configuration document to set up exception rule adjustment activities.

 

Because customer requirement is, there is a common problem customers do not pay the exact amount at the point of settling the invoices. It can be an slightly over payment or an underpayment. However the receivable must be settled with the slight difference.

 

To cater this requirement I have the general understanding that Exception Rules will do the needful. But I am not fully aware of the configuration steps and how it is used in the receipt creation window. Also how to reconcile these through automatic reconciliation process.
