A Revenue Cloud Customer has posted a cash payment that was created on Account A...

In Salesforce Revenue Cloud, if a cash payment has been posted to the wrong account by mistake, the appropriate steps to correct this would be to first unallocate the payment if it has been allocated. This means that the payment is no longerlinked to any particular invoice or order1. Once the payment has been unallocated, a refund should be created for the incorrect payment1. After the refund has been processed, a new payment can then be created for the correct account (Account B in this case)1. This ensures that the payment is correctly associated with the right account and invoice1. References
