Hi Jinoy,
Did you pick the components and bring move them to a KIT WC? Also is this KTS scenario initiated from ERP or EWM? I believe in both cases you should have both an ID and ODO, you then need to pick the ODO to a KIT WC there you can post and consume stock...
I might be off but I am testing the same scenario (KTS initiated from ERP) and i am able to consume the stock and create the Kit Header.
Hope this helps.
