Transporting Table Contents

When i try to add table contents to a transport I m doing the following

1. Going to SE10, double clicking on the Development correction task in the transport to which I want to add the Table contents

2. Putting object name TVARVC Object type TABU, Program ID is R3TR.

3. Then I click on Object with keys button and enter the key field value in TVARVC table that i want to include. But i get the following error.

"Request/task TD1K912931 (MYUSERID) is assigned to a different client"

What m i doing wrong?

Will give points for the right answer. Thanks for reading.
