Difference between SD incompletion log status groups 00 and 01

Status group 00: no columns checked.

When assigned to a field that is incomplete in the sales order, the orders goes on incomplete log, but all subsequent documents such as delivery and invoice can be created.

Status group  01: only "General" column checked

Same - When assigned to a field that is incomplete in the sales order, the orders goes on incomplete log, but all subsequent documents such as delivery and invoice can be created.

For a field at item level in sales order, system should give a warning if it is incomplete, but no subsequent documents should be blocked.  Which one of the two should be used? 00 or 01?  And what's the difference?  Based on my testing, they both behave similarly.

Thanks.
