Dear All,

I need the output mentioned below

Table 1

ID 	Req NO		Req Qty

123	R123		10
123	R123		5
123	R124		20

Table 2

ID	Issue No	Issue Qty

123	R123		5
123	R123		5
123	R124		10


Output Should be

ID 	Req No 		Req Qty		Issue Qty
123	R123		15		10
123	R124		20		10

What I have tried:

SELECT DISTINCT tb_Structure_FMR.PC_Mark_ID, tb_Structure_FMR.FMR_RequestNo,tb_Structure_FMR.FMR_Request_Date,
SUM(CAST(tb_Structure_FMR.FMR_Request_Qty AS FLOAT)),
SUM(CAST(tb_Structure_MaterialIssuance.FMI_IssuedQty AS FLOAT)) FROM tb_Structure_FMR INNER JOIN
tb_Structure_MaterialIssuance ON tb_Structure_FMR.PC_Mark_ID = tb_Structure_MaterialIssuance.PC_Mark_ID
GROUP BY tb_Structure_FMR.PC_Mark_ID,tb_Structure_FMR.FMR_RequestNo,tb_Structure_FMR.FMR_Request_Date

You need to GROUP them first, then JOIN them:

SQL

SELECT t1.ID, t1.ReqNo, t1.TRQ, t2.TIQ
  FROM (SELECT ID, ReqNo, SUM(ReqQty) AS TRQ 
          FROM Table1 
        GROUP BY ID, ReqNo) t1
  JOIN (SELECT ID, IssueNo, SUM(IssueQty) AS TIQ 
          FROM Table2 
        GROUP BY ID, IssueNo) t2
    ON t1.ID = t2.ID AND t1.ReqNo = t2.IssueNo
