When you want to use the future date payment function first check if your bank support this payment type.
You can see if this is enable in the account.

If supported you can change your direct bank account setting to use future date payment based on due date or payment discount date.
When you make single payments based on due date or payment discount date you can export with a future execution date.

This is also possible if you are using bulk payments. The only difference is that the dates in the payment run are identical. When 1 date is off you will be prompted and all execution dates will be changed to the export date(execution date)
So alway check your telebanking proposal on bulk payments. If there are multiple dates please allign first before processing the proposal into the payment file.
