Range entries on specification item S.50.06 are checked first. The size range From 1 and To 1 is required. If you do not specify values for the range in these fields, all idents are closed out for this line item. Size ranges 2 through 5 are optional.
The size range check for this sizes is dependent on the setting of the ‘In n Char’ (n=2..5) check boxes in the spec header description tab page. By default, these sizes (if used) are assumed to be numeric, thus numeric sorting is used to check whether the input value is in the defined size range. If the ‘In n Char’ check box is set for a specific size, alphanumeric sorting is used.
This logic is the same for size ranges 3 through 5.
