Hello A.N Reddy,
There is a confusion here. Are you talking about WM or EWM.
If it is WM, then, I would suggest you to enable, Manual Storage Bin Input for respective WM Movement Type in WM Movement Configuration. That will request you to enter Storage Bin Manually during TO Creation.
If it is EWM, For your process type, Make Search Seq field as Blank and keep your Putaway Rule as " No Putaway Rule ". This will request to you to enter the storage bin Manually during Warehouse Task Creation Process.
In EWM Outbound Process, you have to empty your search criteria in your Pick Rule.
Regards,
Sathish
