When the Order is created in AX, the Location on the Sales Order Line has a Location of 'SALES'. (It pulled from the Retail default location on the Warehouse that is linked to the HOUSTON) This is not correct as if you attempted to Release to Warehouse using standard WHS Processing to create Sales picking work, the Work would not get created specifically because you'd encounter the following error message:
"You can't create a load line for this order line because it contains inventory dimensions that are invalid. You cannot reference inventory dimensions that are located below the location dimension in the Reservation Hierarchy. Remove the invalid dimensions from the order line."
