For IMS sources, you cannot select a code page in the connection properties.

If a mapping includes multi-group source with more than two tables that have duplicate column names, the mapping fails.

If a mapping includes multi-group source that has more than one transformation for the same connection or data map, the mapping fails.

Mappings are not populating all of the target columns and duplicate column names end with a number.

If a mapping includes source objects that have special characters in their names, the associated mapping task will fail because it cannot import the source metadata. Special characters include s #, $, @, %, *, !, and ~.

Workaround: Ensure that none of the mapped source objects have names with any special character. Rename the objects if necessary.
