The order sequence in which the tier groups are listed on the Tier Groups list page is important when you have data overlap across tier groups. Data overlap across tier groups can occur when the tier group segment coverages have overlapping or common pairs.

For best practice, avoid tier group data overlap when possible by carefully designing segment criteria per tier group. When a SKU must belong to more than one tier group for some reason, then the most important tier group should be ordered higher in the list than the other lower priority tier groups.

When executing the Tier Group OTF process, data overlap across tier groups does not matter and Tier Group ordering does not matter. Tier Group sequencing only applies when using tier groups in pricing policies.
