In this activity, you can use customer exit
V53W0001 (function module EXIT_SAPMV53W_001) to sort the
delivieries according to your specific requirements.
Before the wave picks are sorted, the deliveries are sorted according to date,
time and delivery priority. In accordance with this sort sequence, the
deliveries are assigned to a wave pick. In this way, it is ensured that
primarily deliveries with high priority are assigned to wave picks.
Execute this activity if you wish to have a customer-specific sort sequence.
In this case, the deliveries - which are already sorted by delivery priority -
are sorted again according to the user exit.
