Replenishment Workbench Results Issue

We have gone through and set up all the parameters related to Replenishment manual moves at the both the Part Bin and Part Warehouse levels as well as setting the Company Config parameters as well.
The parts were are testing have zero on hand, but we are not getting any results showing in the replenishment workbench. I’m not sure what I am missing as I should be seeing results in this workbench.
