This looks like homework so I will not give you a complete solution. Furthermore I will assume you are on SQL server.

1) Create a stored procedure[^], easy.

2) Use UNION ALL[^] to concatenate two outputs of the same structure.
Hint: How do you subtract qauntities in tbl3?

3) Use SUM[^] aggregate function to add the quantities.
Hint: What do you need to put in GROUP BY[^] clause?

4) Insert the results into a temporary table using SELECT INTO[^]. Temporary table name starts with a hash symbol (#).
Hint: How do you make the table visible outside your stored procedure?

Cheers

SQL

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

ALTER Procedure [dbo].[sp_rpt_StockSummary]

AS
Begin

SELECT P.ID, P.ProductName,P.ProductCode,COALESCE(cash.CashQuantity,0) + COALESCE(credit.CreditQuantity,0)- COALESCE(Oreturn.ReturnQuantity,0) as TQty

from dbo.Inv_ProductName P
	 

LEFT JOIN (select SUM(Quantity) as CashQuantity, ProductID from Inv_PurchaseCashDetails GROUP BY ProductID ) cash ON P.ID = cash.ProductID
LEFT JOIN (select SUM(Quantity) as CreditQuantity, ProductID from Inv_PurchaseCreditDetails GROUP BY ProductID) credit ON P.ID = credit.ProductID
LEFT JOIN (select SUM(Quantity) as ReturnQuantity, ProductID from Inv_PurchaseReturnDetails GROUP BY ProductID) Oreturn ON P.ID = Oreturn.ProductID

End
