InventDimId is a mandatory field for some tables. If you don't use it, you can left it blank: Ssss.InventDimId = InventDim::inventDimIdBlank();

While select InventSum   Join InventDim   where inventSum.InventDimId            == InventDim.InventDimId &&             inventSum. inventLocationID == InventDim. inventLocationID    Group By inventLocationID {       write logic here for }
