Yes, use explicit join syntax, viz

Select mc.MCatID, mi.MItemID, mc.MCatName, mi.MItemCode,
mi.MItemName, mi.Price, mi.Sales
From MCat mc
JOIN MItem mi
ON mc.MCatID = mi.MCatID
Order by mc.MCatName, mi.MItemCode

and set MItem as the KeyRelation

Then put an update statement for MItem in the EditSQL property of the dataset.

You can only update one side of a joined dataset.
