Forum Post: Relation between purchline,VENDINVOICETRANS VENDPACKINGSLIPTRANS

I am not able to determine the relationship between these tables. I am getting duplicates. please help if i can join VENDINVOICETRANS and VENDPACKINGSLIPTRANS . That would be great as well. FROM dbo.PURCHLINE pl LEFT OUTER JOIN dbo.VENDINVOICETRANS vt on pl.PURCHID = vt.ORIGPURCHID AND pl.ITEMID = vt.ITEMID AND pl.INVENTDIMID = vt.INVENTDIMID LEFT OUTER JOIN dbo.VENDPACKINGSLIPTRANS vp AND pl.PURCHID = vp.ORIGPURCHID AND pl.ITEMID = vp.ITEMID AND pl.INVENTDIMID = vp.INVENTDIMID
