What is the relationship between OPOR, OPDN and OIGE Table ?

Question

Dear Experts,
We want to develop one report as per project wise Item Consumtion.
We want data from Purchase Order, Goods Receipt PO and Issue for Production.
The purpose of this report is to find out that what item should create PO
and based on that PO what the GRN should be taken
and based on that GRN this particular item should used for that project
which mentioned in GRN at the time of Item selection.
We develop an Query for that but this query are not as per standard process to get data.
select
OPOR.CardCode as VendorCode, OPOR.CardName as VendorName,
POR1.ItemCode as POItemCode, POR1.Dscription as POItemDesc,
OPOR.DocNum as PONo, OPOR.DocDate as PODate, OPOR.DocDueDate as PODueDate,
POR1.Project, POR1.OpenQty as PendingQty, POR1.Quantity as POQty,
PDN1.Quantity as GRNQty, IGE1.Quantity as IssueQty,
((POR1.PriceBefDi-(POR1.PriceBefDi*POR1.DiscPrcnt/100))*POR1.Quantity) as 'POPrice'
from OPOR
inner join POR1 on
POR1.DocEntry=OPOR.DocEntry
LEFT JOIN PDN1 ON
POR1.DocEntry= PDN1.BaseEntry AND
POR1.LineNum=PDN1.BaseLine
Inner JOIN OPDN ON
PDN1.DocEntry = OPDN.DocEntry
Left join IGE1 on
IGE1.ItemCode=PDN1.ItemCode and
IGE1.Project=PDN1.Project
WHERE 
POR1.Project='{?Project}'
Can anybody tell me that how i can create standard query as per SAP Standards.
Thanks & Regards,

Hi,
Try this query for production order issued serial number.
SELECT T0.[DocNum] as Prod#, T0.[CardCode] as CustCode,T0.[OriginNum] as SO#,T0.[Project] as JobNo, T0.[ItemCode], T1.[ItemCode], T1.[IssuedQty], T3.[IntrSerial],T0.[Comments] as Remark
FROM OWOR T0  INNER JOIN WOR1 T1 ON T0.DocEntry = T1.DocEntry left join  SRI1 T2 on  T2.[BsDocEntry] = t0.docentry and T1.[LineNum] = T2.[BsDocLine] inner join  OSRI T3 ON T2.SysSerial = T3.SysSerial and t3.itemcode = t2.itemcode
WHERE T2.[BsDocType]  = '202' and  T0.[Project]  = [%0] and  T2.[BaseType] = '60' and T0.[Status] IN ('r','l')
GROUP BY T0.[DocNum], T0.[ItemCode], T1.[ItemCode], T1.[IssuedQty], T3.[IntrSerial],T0.[Project],T0.[CardCode],T0.[OriginNum],T0.[Comments] order by T0.[DocNum]
