TO for Deliveries Groups

Hello Masters

I hope everything is going fine

I have a doubt I would like to Group Deliveries in TXN VL10E, in order to create L Groups to do the picking in WM by group in txn LT43. This is for a new WM implementation.

I can create the groups in VG01 but when I try in TXN LT43 to create my TO's I dont have any TO created. Please somebody can explain me the TXN LT43 and if I need to do some customizing to use this TXN in my WN

Thanks in advance for your help

Kind Regards

Albert
