Once setup is complete, the next step is one people often forget. I did :-). I had to dig back to training manuals I created back in 2012. You need to navigate to Retail > Periodic > 'Process delivery modes' and run this job (Figure 3). It explodes out the delivery modes for the stores which you can verify by going to the retail channel you want the delivery mode on and click on the 'Modes of delivery' under the setup form (Figure 4). Finally, you'll need to push the delivery modes to the store via the appropriate distribution group. Default data has this as the 1120 job (Figure 5). Once run, you can verify the data processed to the stores by clicking on the 'history' button, clicking 'Process status messages', and verifying the status messages for the channels (also Figure 5 for Houston channel).
Hope this helps someone out!
