When Conditional GST is turned on and when a customer invoice or credit note is posted, Conditional GST will be posted (instead of actual GST Payables). In the case of invoice, Conditional GST will be credited. However, with the credit note, Conditional GST will be debited (as the customer balance is credited). As per the functionality of Conditional GST, when the invoice gets settled with the payment, the amount from Conditional GST will be moved to the GST Payables account. The standard reimbursement functionality only picks up the 'Credit' transactions and leaves the debit transactions at the time of settling the credit note. This is leaving the balance on Conditional GST and every time users will have to do a manual journal to move the balances from Conditional GST to GST Payables account.

The improvement requested as part of this Idea is that Conditional GST should also be reversed when the reimbursement functionality is run on the credit notes.
