Thanks for the reply.

This is the pseudocode:

1- The client request the data from a object inside MTS
somtething like MyData:=MyServer.MyObject.GetData(Filter,Order);
2- In the client, change is done for the user
3- The client request a update to the same object..
Like it:
MyServer.MyObject.SendData(MyData)

Inside the server, i loop for the changed records (i use updatebatch), update each one, and return ok or not ok to the client. The rs is passed by ref...

The problem is that in the 1- step, MTS clear the source property...

In VB happend it?
