This business name has already been used by the target table <table name> in the repository and has been renamed to <table name>. You must save your changes before renaming this table.
You changed the value for the business name in a target definition. You then attempted to enter the old business name in another target definition. This is not allowed. For example, you changed the business name in the target T1 from B1 to B2. You then entered the business name B1 to another target definition, T2.
Save the changes in the repository after entering the new business name for the target definition. Then you can use the old business name for another target definition.
