I have a problem with delivery note.
In sales order I have two item lines
Item 10 Normal sales order material item catecory TAN
I have split this line in scheduled lines tap.
Item 20 I have material (not batch managed) item catecory TAW
When I create delivery (VL01N) note item 10 works fine and I can make several delivery notes.
But item 20 allows me to do only one delivery note.
If I try to create another one system gives an error "Outbound delivery is on backorder (check shipping deadline)"
If I split this material system gives a same error.
