Restriction at this moment :
For a formula line of bulk item in packed batch order you are having a LOTID value which can point to only one batch order header for the bulk item

Suggestion :
Having the possibility where multiple LOTID values related to multiple formula lines for bulk item can be stored in some sort of a list under the grouped batch order header for the bulk item
This will be very usefull in order to reschedule using synchronisation function one packed batch order. In this case, all other packed batch orders and the bulk batch order can be resheduled correctly.
