Selectively deletes or modifies sales transactions in Samba 4

Hello,
I am in Canada, and by law we are not allowed to selectively deletes or modifies sales transactions in point-of-sale systems. I am not sure if Samba 4 can do that, if yes so I can not use it, that’s the problem with Tax, Revenue office.

No you can not delete or modify transactions once work period is closed.

Work period, you mean the end of the day?

I mean work period in Sambapos.
