Bank Statement Balance check and float values are used for what functionality?

Summary:

Hi,

We are migrating bank statements / balances for the banks and we would like to check what are the impacts of the balance check, available amount and floating amount in Cash management?

To be able to 0 out the balance check, we are not inputting Opening booked, just the statement line as credit, and then Closing book as 1000. to 0 out the balance check.

But the Available amount is with 1000, do we need to add float days and what will be the impact if we have no float days added on bank statement? Is it okay if we don't add the float days and amount?
