New warehouse but when shipping / issuing / receiving inventory it is still defaulting to the Main Warehouse

I created a new warehouse (ASH) to move special parts out of our MAIN WH and added the BIN names into ASH. I set the primary WH and BINs for these parts to be primary (DMT) and they show as primary, but the users are reporting that “when shipping / issuing / receiving inventory it is still defaulting to the Main Warehouse”. I feel like there is a setting that I missed in my DMT work. To date, via DMT, I have run the PlantPlant with these columns Company, PartNum, Plant, PrimWhse and the Part Warehouse with these Company, PartNum, WarehouseCode, DefaultWhse, Plant, PrimBinNum. I have searched this site, and others with not much luck. Maybe I’m not using the right phrases?? Any help is appreciated, thank you, WWC.

AFAIK, this is in the Site Config UI
