Why the Bundle item not getting published by RTAM when a flag ship-independently checked.
We don't publish anything for ship independent bundles. Ship independent bundles rely on the user to look at the components to determine inventory. This is true for all promising APIs as well . Current behavior of RTAM is expected.
RTAM will publish bundle item inventory when ship together flag is checked.
Both the flags Ship Together and ship-independently is used for promising also not only for shipping.
