Can't get the SUM function to work with my query - sql

Question

I'm trying to SUM some warehouse stock values, grouped by zones, but can't get it to work.
The following query returns all materials on stock. Same material is placed on more locations, in more zones. So material AAA can be located on two locations in zone 111, and three locations in zone 222
SELECT Zones.Label,
Materials.Material,
Shelves.Label as ShelfLabel,
Items.StockQty
FROM Zones INNER JOIN
(dbo.LangTexts(null) AS Texts INNER JOIN (WarehouseStatus INNER JOIN
(Shelves INNER JOIN (Positions INNER JOIN
(Materials INNER JOIN Items
ON Materials.Material = Items.Material)
ON Positions.ID = Items.Owner)
ON Shelves.ID = Positions.Owner)
ON WarehouseStatus.Status = Items.Status)
ON Texts.TextID = WarehouseStatus.Text)
ON Zones.ID = Shelves.Owner
WHERE Zones.Label IS NOT NULL
ORDER BY Materials.Material, Zones.Label
Output:
output screenshot
As I have tried to markup in the screenshot, I need the total StockQty grouped by zone (label column)
I'm trying to achieve that by modifying the query like this.
SELECT Zones.Label,
Materials.Material,
Shelves.Label as ShelfLabel,
SUM(Items.StockQty)
FROM Zones INNER JOIN
(dbo.LangTexts(null) AS Texts INNER JOIN (WarehouseStatus INNER JOIN
(Shelves INNER JOIN (Positions INNER JOIN
(Materials INNER JOIN Items
ON Materials.Material = Items.Material)
ON Positions.ID = Items.Owner)
ON Shelves.ID = Positions.Owner)
ON WarehouseStatus.Status = Items.Status)
ON Texts.TextID = WarehouseStatus.Text)
ON Zones.ID = Shelves.Owner
WHERE Zones.Label IS NOT NULL
GROUP BY Zones.Label
ORDER BY Materials.Material, Zones.Label
But it keeps returning the following error.
Msg 8120, Level 16, State 1, Line 6
Column 'Materials.Material' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
I have been dealing with such error before, but don't understand exactly what I'm doing wrong. Sometimes I succeed by changing the query back and forth, but this time I really stuck.
Hope that someone is possible to guide me.
Thank's in advance.
As the column Shelves.Label actually not bring any value in this matter, I ended up with the following query based on #Md.SumanKabir's answer.
SELECT Zones.Label,
Materials.Material,
SUM(Items.StockQty)
FROM Zones INNER JOIN
(dbo.LangTexts(null) AS Texts INNER JOIN (WarehouseStatus INNER JOIN
(Shelves INNER JOIN (Positions INNER JOIN
(Materials INNER JOIN Items
ON Materials.Material = Items.Material)
ON Positions.ID = Items.Owner)
ON Shelves.ID = Positions.Owner)
ON WarehouseStatus.Status = Items.Status)
ON Texts.TextID = WarehouseStatus.Text)
ON Zones.ID = Shelves.Owner
WHERE Zones.Label IS NOT NULL
GROUP BY Zones.Label, Materials.Material
ORDER BY Materials.Material, Zones.Label

Answer 1

The correct query would be :
SELECT Zones.Label,
Materials.Material,
Shelves.Label as ShelfLabel,
SUM(Items.StockQty)
FROM Zones INNER JOIN
(dbo.LangTexts(null) AS Texts INNER JOIN (WarehouseStatus INNER JOIN
(Shelves INNER JOIN (Positions INNER JOIN
(Materials INNER JOIN Items
ON Materials.Material = Items.Material)
ON Positions.ID = Items.Owner)
ON Shelves.ID = Positions.Owner)
ON WarehouseStatus.Status = Items.Status)
ON Texts.TextID = WarehouseStatus.Text)
ON Zones.ID = Shelves.Owner
WHERE Zones.Label IS NOT NULL
GROUP BY Zones.Label, Materials.Material, Shelves.Label
ORDER BY Materials.Material, Zones.Label
You need to use the columns in GROUP BY which are not used in any aggregate functions like SUM
You can get more information on how to use GROUP BY Here

Answer 2

The problem here is that your grouping does not match your select. You select 3 columns Zones.Label, Materials.Material and Shelves.Label, but you group only by Zones.Label. Therefore, it does not know what to do with the 2 other columns.
Either you have to aggregate them like you did with the sum or you have to add them to the grouping.
