What causes this issue?

The complete key consists of the individual keys defined in the data

relationship type <ls>Leading</>.
The key length of an entity type with <DS:DE.USMD_USAGE_TYPE>storage and
use type</> <ls>1</> exceeds the maximum length of the enqueue key. This
causes the system to lock more values than need be.
The complete key must not exceed the following length:
111 characters for entities with an edition
117 characters for entities without an edition

the related entity types so that the complete key has a maximum length
of 111 characters (or 117 characters for entities without an edition).
