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

INCLUDE INCL_MIGRATION_SCENARIO
Check whether both keys are really needed or if one of the keys can be

The message is also issued if &V2& is a generic primary key whose

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.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
