Currently, upon manually changing the Route number on versions 10.0.42 and 10.0.43 against 2 different Planned orders with the same Item number then grouping these 2 Planned orders, a new Planned order will be created, however, the manual Route number change is overlooked by the system and the old Route number get assigned to the newly created Planned order. If we proceed further to Firm this Planned order, a Production order will be created against the wrong Route number. The users wish to have the system assign the correct Route number to the Grouped Planned orders.
