Xstore 18 Self Checkout

Hi,

is it possible to use self checkout register mode with till accountability?

I've been able to use it in register accountability, just by login and press start. With register accontability I've tried the following scenarios without success:

without any till issued in the store.

with a till issued to the user that logs in.

with a till attached via regular mode and then login in SCO mode.

All scenarios raise an error related to till, either no till attached or that user does not have any till. My expectation is that when on SCO mode there would be no need to have tills.
