Hi Cetin
You may already be aware of this, but just in case...
Note that the shape provider pulls over all records from the child select, unless you use a parameter. In other words, if you have a main select as "select * from customers where ID_Customer = ..." with an append "select * from orders", all orders for all customers will be pulled over the wire.
This is "by design", ref. KB article Q196968 - PRB: SHAPE Provider Pulls Down All Records in Child Table
