I need help please

I noticed that when I do not do POS CLOSE VOUCHER for a day … I cannot make POS CLOSE VOUCHER for that day.

Example: On 26-08-2021 I could not do POS CLOSE VOUCHER and next day (27-08-2021) when I try to do POS CLOSE VOUCHER I select the date 26-08-2021 (as in the picture) Period Start Date + Period End Date They have not changed and so I find Total Collected Amount is (ZERO) because there is no Cashier Closing yet for 27-08-2021 day

… How can I do a POS CLOSE VOUCHER for previous days since I cannot do a POS CLOSE VOUCHER for all branches in one day?? Thanks to all
