Hi All,

We have migrated from 11i to R12, there are duly accounted migrated prepayment .When we are applying this existing prepayments to standard invoices and try to do accounting for standard invoice after application, the accounting is neither happening from workbench as well as create accounting program.

However if we create new prepayments and apply the same to standard invoice, standard invoice is duly accounted.

Could you please help us on this.
