pick slip number when running shipment request
I understand we don't generate any picks or pick slip number when running shipment request.
But do we have any equivalent? I mean if you have the order 12345 and you have 2 partial releases running 2 shipment request I would like to know if there is a unique id somewhere to identify this release number for particular order.
So similar to the concept of pick slip number when running pick wave.
If possible let me know field name and in which table is stored. I was looking in wsh_delivery_details table but could not really find this...
Thanks in advance
