From the manual
Enter a code that determines whether a work order can be changed at a
particular status. The lock applies to records in both the F4801 table and
the F4802 table. Values are:
Blank: Do not lock the work order.
1: Lock the work order.
2: Lock the work order with a completion date.
3: Do not lock the work order with a completion date.
4: Lock the work order, the parts list, and the routings.
5: Lock the work order, the parts list, and the routings with a completion
date.
6: Lock the order type and the work order type only.
Hope it helps.
