Currently, marking information is not displayed in Marking form after generating picking list.
However users often check marking information after picking/delivery.

It is possible to check the marking information with following operation but it's time consuming for end users.
1. Select Sales order lines to check marking information.
2. Select Transaction from Inventory pull-down menu.
3. Click Transaction details.
4. Check Reference lot field in General tab.

Please add to display marked transaction information in Marking form so that end users easily check marking information.
