Batch does not get created automatically

Hi,

I've activated and maintained internal number assignment in batch number assignment. I've also set that for mvt 101 and 561 batches should be created automatically (C Automatic / no manual creation). Now during GR for a 561 in MIGO, the batches number is not created automatically, unless I hit the check button. When I click on the classification button, the system says that I need to enter a batch but system does not create one.

When I use tcode MSC1N, the system does create a number upfront.

Any ideas?
