Crystal Reports 2020 - GROUP BY-CodePudding

How do I use Group BY to display only one record in CR? I have narrowed down the records I want to use, but because of joining the LEFT JOIN tables in CR, it duplicates the records. I only need to display one and I don't know how to use CR Grouping. THIS my record selection: {TraElem.TrE_TypTwr} in [1, 2, 3] OR ({TraElem.TrE_TypTwr} = 4 AND {Atrybuty.Atr_Wartosc} LIKE 'Tak' AND {Atrybuty.Atr_atkid} = 15) W MSSQL :

join cdn.twrkarty on TrE_TwrTyp=Twr_GIDTyp and TrE_TwrNumer=Twr_GIDNumer
 JOIN CDN.atrybuty on Atr_ObiTyp=Twr_GIDTyp AND Atr_ObiNumer=Twr_GIDNumer
WHERE (TrE_GIDTyp=2037 AND TrE_GIDNumer=38012)
        AND
        (
                TrE_TypTwr in (1, 2, 3)
                OR
                (
                        TrE_TypTwr=4
                        AND
                        (
                                SELECT Atr_Wartosc FROM CDN.Atrybuty WHERE Atr_ObiTyp=Twr_GIDTyp AND Atr_ObiNumer=Twr_GIDNumer AND Atr_AtkId=15
                        ) like 'Tak'
                )
        )
