Hello Mihailo,
I'm a functional guy, but I think I got what you said. My point now is, where I can insert this serial number when I'm doing the transfer bin to bin. Technically a transfer bin to bin doesn't not generate a TR/TO, for example, transaction LT10.
My last try was creating a 309 in MB1B, but the system is trying to create a TO, but the TR is not created. I think 309 is not allowed for TR creation.
Thanks
Antonio
