Destack parameter to describe how incomplete books are dealt with
This destacking parameter sets whether partially complete books (part books) are allocated to the overflow station. A part book is a book that has a book height (number of parts) less than the maximum book height for that material.. (In the diagram above the measuring rod indicates the maximum book height - in this case 6 boards. The part book is only 4 boards or 4 parts high).
Y - send part books to overflow station
N - do not send part books to overflow station
If a book of boards is less than the maximum book height all the books of parts produced by cutting those boards are part books even if some of the books are for the same part type. That is, each part book is transferred directly to the station and the part books are not combined to make full books.
