Issue
Support has confirmed that in Payments Basis GST the Calculation appears to be flawed in receipt/refund allocation results.
When a reversal is done, a new payment line should be created in the period that it is reversed in. This leaves a visible trail as well as showing in the GST return correctly as a positive in the original payment period and a negative in the reversal payment period.
Workaround
Manual reconciliation and journaling.
Resolution
