Add delivery info to query in SAP Crystal Reports

问题

Below is a query linking Purchase Orders to Sales Orders. My understanding is that in order to include delivery doc # to this report, I need to add one more table - ODLN (so there would be an additional field titled "Delivery Doc#" aka [ODLN.DocNum]). My problem is I'm not sure how to join ODLN in the below query without messing anything up.

ODLN.DocNum pretty much verifies that the PO did get placed at the time of the SO submission.

SELECT DISTINCT
       o.CardName AS 'Customer Name'
       ,(isnull(c1.Street,'') + ', ' + isnull(c1.Block,'') + ', ' + isnull(c1.City,'') + ', ' + isnull(c1.[State],'') + ' ' + isnull(c1.ZipCode,'')) AS 'Customer Address'
       ,cpr.[Name] AS 'Customer Contact'
       ,cpr.Tel1 AS 'Customer Phone'
       ,cpr.E_MailL AS 'Customer Email'
       ,o.DocNum AS 'Sales Order #'
       ,p.DocNum AS 'PO # to Barracuda'
       ,l.ItemCode AS 'SKU'
       ,l.Dscription AS 'Desc'
       ,l.Quantity AS 'Qty'
       ,l.Price
       ,s.SlpName AS 'Sales Rep'
FROM 
       ORDR o
       INNER JOIN RDR1 l ON o.DocEntry = l.DocEntry
       LEFT JOIN POR1 p1 ON l.DocEntry = p1.BaseEntry AND l.LineNum = p1.BaseLine
       LEFT JOIN OPOR p ON p1.DocEntry = p.DocEntry
       INNER JOIN OCRD c ON o.CardCode = c.CardCode
       INNER JOIN CRD1 c1 ON c.CardCode = c1.CardCode AND c.BillToDef = c1.[Address]
       LEFT JOIN OCPR cpr ON c.CntctPrsn = cpr.[Name] AND c.CardCode = cpr.CardCode
       INNER JOIN OITM itm ON l.ItemCode = itm.ItemCode
       INNER JOIN OITB i ON itm.ItmsGrpCod = i.itmsGrpCod
       INNER JOIN OSLP s ON o.SlpCode = s.SlpCode
WHERE
       o.Canceled = 'N'
       AND c1.AdresType = 'B'
       AND i.ItmsGrpCod = 109
       AND o.DocDate BETWEEN '6/01/2014 00:00:00.000' AND '9/30/2014 00:00:00.000'
ORDER BY
       o.DocNum

From comments, it is clear that you aren't sure what fields to use to join the ODLN to your current query.

I would follow the money.

If I recall correctly, ODLN.TransId joins to OJDT.TransId, and OJDT.BaseRef joins to OPOR.DocNum.

What is unclear from your question is if you only want those POs that have a Delivery Doc, only those that don't, or all POs (ordered, or not, by those that have Delivery Docs). Once we know that, we can tell you whether to use left or inner, how to handle Null, etc. But frankly, when it comes to SAP, that part is trivial.
