Difference between LZ & OR order types.

Hi Gurus,

Please clear my doubt,We can create order for a particular line item and give scheduled in the schedules tab of the Sales order OR.and can do delivery on the respective dates.

The same functionality can be performed in LZ.We can crete schedules in scheduling agreement also.

Can any one please say me the reason behind using 2 different order types OR & LZ.Where both performing same work

Any difference there between 2 order types.

Thanks,
