and following my stored procedure

alter proc [dbo].[CountDownlineNode]
(
 @memberid nvarchar(50)
)
as
begin
;with cte as (
        select
              Member_Name,  Member_ID, Upline_ID, Placement_Leg,
                null lnode,
                null rnode
        from Table_DownLineList where Member_ID =@memberid     
        union all
        select
                t.Member_Name, t.Member_ID, t.Upline_ID, t.Placement_Leg,
                ISNULL(cte.lnode, CASE WHEN t.Placement_Leg = 'Left' THEN 1 ELSE 0 END) lnode,
                ISNULL(cte.rnode, CASE WHEN t.Placement_Leg  = 'Right' THEN 1 ELSE 0 END) rnode
        from Table_DownLineList t
        inner join cte
                on  cte.Member_ID=t.Upline_ID
)
select
        @memberid Member_ID,
        SUM(lnode) LeftNodes,
        SUM(rnode) RightNodes
        from cte   OPTION( MAXRECURSION 100)
end
GO

when we execute my stored procedure as:

exec CountDownlineNode 'LDS'

and I have found the following error:

Msg 530, Level 16, State 1, Procedure readDownlinedetails, Line 9
The statement terminated. The maximum recursion 100 has been exhausted before statement completion.

when I run your code above with no changes, I get:

Member_ID                                            LeftNodes  RightNodes
-------------------------------------------------- ----------- -----------
LDS                                                          6           1
Warning: Null value is eliminated by an aggregate or other SET operation.

(1 row(s) affected)

to get more iterations in the CTE, change:

OPTION( MAXRECURSION 100)

to

OPTION( MAXRECURSION 0)
