I have assigned the Item category determination in VOV4 for each sales doc type
OR - NORM - TANN-TAN.
now, when i create a sales order, i get an error, 'item category is not defined '
I went back to VOV4 and removed the TANN(higher level Item Category).
Now I re-checked the order and the error disappeared.
My Issue is resolved, but I am not sure why does the Higher level item category should be removed for the item category determination? Where as the Item Category determination rule says it is a combination of order type,item category grouphigher level item categoryitem usage+default item category.
Can anyone explain this please?
