What causes this issue?

The table key &V1& is unique and &V2& is not unique. However, the
components of &V1& are a subset of &V2&, which means that &V1& is more
selective than &V2&.
INCLUDE INCL_MIGRATION_SCENARIO
Check whether both keys are really needed or if one of the keys can be
removed.
The message is also issued if &V2& is a generic primary key whose
uniqueness is unknown. In this case, the worst case scenario is assumed

secondary key is a subset of the primary key at the same time, the
primary key must be unique. Check the definition of the primary key and
define it as unique if appropriate.
