Question

I have data below

CREATE TABLE #tbl_item (IT_ID INT,IT_Name varchar(50))
CREATE TABLE #Importer (IM_ID INT,IM_Name varchar(50))
CREATE TABLE #tbl_GRNM (GRN_ID INT,IM_ID int)
CREATE TABLE #tbl_GRND (GRN_DID INT,GRN_ID int,IT_ID int,GRN_QTY int)
CREATE TABLE #tbl_Dispatch_Master (D_ID INT,IM_ID int)
Create Table #tbl_Dispatch_Detail (DID_ID int,D_ID int,IT_ID int ,D_QTY int)

INSERT INTO #tbl_item VALUES(1001, 'A')
INSERT INTO #tbl_item VALUES(1002, 'B')
INSERT INTO #tbl_item VALUES(1003, 'C')

INSERT INTO #Importer VALUES(101, 'Akhter')
INSERT INTO #Importer VALUES(102, 'Babar')

INSERT INTO #tbl_GRNM VALUES(201, 101)
INSERT INTO #tbl_GRND VALUES(1, 201,1001,5)
INSERT INTO #tbl_GRND VALUES(2, 201,1002,4)

INSERT INTO #tbl_GRNM VALUES(202, 102)
INSERT INTO #tbl_GRND VALUES(3, 202,1002,6)
INSERT INTO #tbl_GRND VALUES(4, 202,1003,4)
INSERT INTO #tbl_GRND VALUES(5, 202,1001,2)

INSERT INTO #tbl_GRNM VALUES(203, 101)

INSERT INTO #tbl_GRND VALUES(6, 203,1001,3)
INSERT INTO #tbl_GRND VALUES(7, 203,1002,2)

INSERT INTO #tbl_Dispatch_Master VALUES(301, 101)
