Hi Kalyan, You will be hitting movement 321, you can do output trigger for movement type 321 with label settings, only thing you need to do give output about (a) and (b).. system can get quantity from 321 material document too ..why you want to control manually .. i think then label will be misleading..It also seems you have WM in place that is reason you asking for destination bin ID. that involved WM
You can trigger output from material document but I think you have enhance MSEG table and MIGO custom screen to mention your specified quantity so that when you re-print system pick that.. But still think that misleading information
