Count the number of items in a warehouse

[peterMza]

Hello,

I need to count the number of items in a warehouse. I already have the query to retrieve the items, but I'm not sure how to use $count to perform the count

URL : 

https://<my sever>:50000/b1s/v1/$crossjoin(Items,Items/ItemWarehouseInfoCollection)?$expand=Items($select=ItemCode,ItemName)&$filter=Items/ItemCode eq Items/ItemWarehouseInfoCollection/ItemCode and Items/ItemWarehouseInfoCollection/WarehouseCode eq '1'

Thanks!.
