Hi Kim,
 
Thanks for the reply.
 
I have resolved the issue this morning. But its a very descriptive as well as useful reply from ur side.
That will be very useful for us to optimize the code as well as improve performance. I will try this thing in my code and check it eventhough i have solved it.
 
Thanks again.

Well, you'll get this error if the entity you're trying to add already has its .EntityManager property set and the entity is in a non-detached state.  How did the entity come into existence?  Did you query for it, restore it from an entity set, or create it?   If you do want to add the entity to this EntityManager, first call entity.RemoveFromManager to detach it from its current EntityManager.  Once added, the entity's state will be Added, and when SaveChanges is called it will be inserted to the database.  If you don't want this behavior, then look at using mgr.ImportEntities to "move" entities between Entity Managers.

Hi,
 
I m getting the following error while adding entity to entitymanager
 
"This Entity already belongs to another EntityManager"
 
Following is the code snippet where i get the error

DataSet.AddEntity(mmp);

- DataSet is EntityManager

Can u please guide me what can be the error. AS i m not adding this entity to anywhere in the application thenalso getting the error.
 
Thanks in advance.
