I have a model of a distribution center. Boxes (pallets) come in, are placed in staging racking, transported to pushback racking, then transported again to staging racking on the other end of the distribution center. I am having an issue where the Pushback racking accepts inputs into the racking but it not providing any outputs. This is occurring for Pushback Rack 1-5 and Rack 5. The other racks are behaving like I anticipated. I have tried using transport and not using transport with the same results. Any help would be greatly appreciated!
