This business name has already been used by the source table <database name>:<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 source definition. You then attempted to enter the old business name in another source definition. This is not allowed. For example, you changed the business name in the source S1 from B1 to B2. You then entered the business name B1 to another source definition, S2.
Save the changes in the repository after entering the new business name for the source definition. Then you can use the old business name for another source definition.
