Sometimes the "Delete" icon is engaged, which makes it impossible to delete the "Credit & Refund".
This is the case when the period in which the transaction to be reversed is in a closed bank reconciliation. It is not necessary for the transaction to be selected as part of the period's revenue in the bank reconciliation to prevent the transaction from being reversed. It is sufficient that the bank reconciliation for the period in question is completed and closed to prevent the transaction from being reversed.
This is also the case when the period in which the transaction to be reversed falls is subject to a tax rebate in the software.
Result:
If only the bank reconciliation is done for the period in question, reopen it will make the "Delete" icon available again;
If the tax remittance is made for the period in question, it will not be possible to make the "Delete" icon available again. The "Credit & Refund" will have to be countered by the opposite transaction, i.e. a "Purchase & Payment", which will be taken into account in the next tax remittance.
