I come across a very tricky problem. Vendors send ASN to us by EDI, here they also input vendor batch in the ASN, now in our system, I can see the inbound delivery generated, and the vendor batch is right there, eveything looks no problem. But the problem is, when we use the inbound to do GR by MIGO, I can see the vendor batch column is empty, it doesn't take into here, why? Do I need do something like customization to realize it?
You need to use an exit exit_sapleinr_002 to adopt the vendor batch from the Inbound delivery, see 73713 - User exit: adoption of batch no. from shipping notification,
this old note implemented the the exit, so it should be there in your system, you only need to add your coding
