Not able to store newly inserted identity value into temp table using OUTPUT Clause

I tried this way to store all newly inserted identity type value by OUTPUT clause.

CREATE TABLE #tmptblSectionLineItemTemplate
(
    ID INT Identity
)


BEGIN --INSERTNG/UPDATING Unique Section into tblSectionLineItemTemplate
    MERGE INTO tblSectionLineItemTemplate Trg
    USING 
    (
        SELECT TOP 100 PERCENT s.SectionID AS SectionID, l.ID AS LineItemID
        FROM (SELECT DISTINCT Section,LineItem FROM #TmpTenQKData) a RIGHT OUTER JOIN TblLineItemTemplate l ON a.LineItem = l.LineItem 
        RIGHT OUTER JOIN tblSectionTemplate s ON a.Section = s.Section
        WHERE s.TickerID=@TickerID AND l.TickerID=@TickerID 
        ORDER BY s.OrderID,l.ID

    ) AS Src 
    ON ISNULL(Trg.SectionID,0) = Src.SectionID AND ISNULL(Trg.LineItemID,0) = Src.LineItemID

    WHEN NOT MATCHED THEN 
        INSERT 
        (
            SectionID,
            LineItemID,
            Active,
            InsertDate,
            UserID
        )
        VALUES 
        (
            Src.SectionID, 
            Src.LineItemID, 
            'A', 
            GETDATE(), 
            @UserID
        )
        OUTPUT inserted.SectionDetl_Id  INTO #tmptblSectionLineItemTemplate(ID);
END 

SELECT * FROM #tmptblSectionLineItemTemplate

When i execute the above code then i am getting this error. Cannot insert explicit value for identity column in table 'tblSectionLineItemTemplate' when IDENTITY_INSERT is set to OFF.

Please tell me where i made the mistake. How can i store all newly inserted identity value of target table tblSectionLineItemTemplate into temp table?

Thanks
