When you release a wave using Wave Release (4.15.8), the system automatically creates release groups—a collection of orders within a wave if you set options in Wave Planning Control. You can then assign those release groups to shipping lanes by carrier.

If you do not create release groups automatically, you can manually create and activate them using Wave Release Groups Creation (4.15.9). Use Wave Release Groups Activation (4.15.10) to only activate the release groups.

See here.

The frames that display for both programs are similar to Wave Release (4.15.8); however, there is no Order Priority field in Wave Release Groups Creation and Wave Release Groups Activation.

For field descriptions, see here.

You must select the release groups individually and launch them.
