Stock Removal using Pick Point

Hi all,

I have configure Storage Type 100 with SU managed and a pick point ST 001.

Once the TO is generated from delivery, the TO information will be from source ST100 to destination ST916.

So I would like to know, how to identify the SU is arrived pick point? If there any status or information can help me to know the status of TO.

Since i need to identify,

1.SU still in the Source Storage Type (TO open)

2.Worker starts transfer to SU to pick point with liftfork

3.SU arrived Pick point

4.Picker picked the material from pick point (TO picked)

5.Picker transferred the material to GI area (TO transferred and completed)

I dun know how to let user know the status of 2 and 3

Thanks in advance.
