Hi Mevin,
I am facing the same problem with EWM-triggered kit to stock deliveries. Can you please share your settings for deliveries and movement types in ECC?
For Inbound I have set up in "Determine Delivery Type for Manufacturing-Related Inbound Deliveries" del.type DIG for KTS and in "Define Item Categories for Deliveries" movement type 521 for DIGN - this works fine.
But for outbound deliveries I have the same problem you mentioned.
Best regards
