Calculating sales, returns, and breakdowns from SQL Server tables

I have 4 tables, namely products, SalesLog, Breakages, SalesReturn.

Product table

CREATE TABLE [dbo].[Products](
[ProductId] [int] IDENTITY(1,1) NOT NULL,
[pName] [nvarchar](30) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[pSize] [int] NULL,
[pPrice] [decimal](10, 2) NULL,
[pPackQty] [int] NULL,
[pGroup] [int] NULL,
[pCode] [int] NULL,
[OpenStock] [int] NULL,
[CloseStock] [int] NULL,
[YrlyOpenStock] [int] NULL,
CONSTRAINT [PK_Products] PRIMARY KEY CLUSTERED 
(
[ProductId] ASC
)WITH (PAD_INDEX  = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

SalesLog table

CREATE TABLE [dbo].[SalesLog](
[SalesID] [int] IDENTITY(1,1) NOT NULL,
[MemoNo] [int] NULL,
[ProductCode] [int] NULL,
[Quantity] [int] NULL,
[Price] [decimal](10, 2) NULL,
[pGroup] [int] NULL,
[pName] [nvarchar](30) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[pSize] [int] NULL,
[BillDate] [nchar](10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
CONSTRAINT [PK_SalesLog] PRIMARY KEY CLUSTERED 
(
[SalesID] ASC
)WITH (PAD_INDEX  = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

SalesReturn Table

CREATE TABLE [dbo].[SalesReturn](
[srID] [int] IDENTITY(1,1) NOT NULL,
[ProductCode] [int] NULL,
[Quantity] [int] NULL,
[pGroup] [int] NULL,
[MemoNo] [int] NULL,
[SalesmanID] [int] NULL,
[Price] [decimal](10, 2) NULL,
[JobShift] [int] NULL,
[BillDate] [nchar](10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[AddedOn] [datetime] NULL,
 CONSTRAINT [PK_SalesReturn] PRIMARY KEY CLUSTERED 
(
[srID] ASC
)WITH (PAD_INDEX  = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

Partition table

CREATE TABLE [dbo].[Breakages](
[breakId] [int] IDENTITY(1,1) NOT NULL,
[MemoNo] [int] NULL,
[SalesmanID] [int] NULL,
[ProductCode] [int] NULL,
[pName] [nvarchar](30) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[Quantity] [int] NULL,
[Price] [decimal](10, 2) NULL,
[pGroup] [int] NULL,
[JobShift] [int] NULL,
[BillDate] [nchar](10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[AddedOn] [datetime] NULL,
CONSTRAINT [PK_Breakages_1] PRIMARY KEY CLUSTERED 
(
[breakId] ASC
)WITH (PAD_INDEX  = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

I need to create a single report to show SalesLOg, SalesReturn and Breakages of a specific date (according to the BillDate column SalesLog, Breakages and SalesReturn) in the following template.

Output required

Code      ItemName     Price     SalesQty     BreakagesQty    SalesReturnQty
 1           A          $10         50              2               2
 1           A          $12         150             1               10
 15          X          $5          56              0               2
 20          Z          $8          121             0               0

Reduced read output column

as you can see that Product "A" was listed twice due to a change in the price of this product. for this I wrote a query:

SELECT     SalesLog.pName, SalesLog.ProductCode, MIN(ItemGroup.gName) AS GroupName, 
           SalesLog.Price, SUM    (SalesLog.Quantity) AS SalesQty, 
           SUM(SalesLog.Quantity * SalesLog.Price) AS SalesValue, 
     ISNULL ((SELECT     SUM(Quantity) AS Expr1 FROM Breakages
        WHERE (ProductCode = SalesLog.ProductCode) AND (Price = SalesLog.Price) AND 
          (BillDate = '07/01/2010') AND (pGroup <> 15) AND (pGroup <> 16)), 0) AS BreakQty, 
     ISNULL ((SELECT     SUM(Quantity * Price) AS Expr1
 FROM         Breakages
        WHERE     (ProductCode = SalesLog.ProductCode) AND (Price = SalesLog.Price) AND 
          (BillDate = '07/01/2010') AND (pGroup <> 15) AND (pGroup <> 16)), 0) AS BreakValue, 
     ISNULL ((SELECT     SUM(Quantity) AS Expr1
 FROM         SalesReturn
       WHERE     (ProductCode = SalesLog.ProductCode) AND (Price = SalesLog.Price) AND 
          (BillDate = '07/01/2010') AND (pGroup <> 15) AND (pGroup <> 16)), 0) AS ReturnQty, 
     ISNULL ((SELECT     SUM(Quantity * Price) AS Expr1
 FROM         SalesReturn
       WHERE     (ProductCode = SalesLog.ProductCode) AND (Price = SalesLog.Price) AND 
          (BillDate = '07/01/2010') AND (pGroup <> 15) AND (pGroup <> 16)), 0) AS ReturnValue, 
     ISNULL ((SELECT     SUM(Quantity) AS Expr1
 FROM         SalesLog
       WHERE     (ProductCode = Products.pCode)), 0) AS CummSales
 FROM         SalesLog 
          INNER JOIN
              ItemGroup ON ItemGroup.gCode = SalesLog.pGroup AND SalesLog.pGroup = ItemGroup.gCode 
          INNER JOIN
              Products ON Products.pCode = SalesLog.ProductCode
       WHERE  (SalesLog.BillDate = '07/01/2010') AND (SalesLog.pGroup <> 15) AND 
              (SalesLog.pGroup <> 16)
GROUP BY SalesLog.pName, SalesLog.ProductCode, SalesLog.Price, Products.pCode, Products.pPrice
ORDER BY SalesLog.ProductCode, SalesLog.pName
