Diagnosis
The complete key consists of the individual keys defined in the datamodel for relationships. These individual keys belong to entities thatare (directly or indirectly) linked through relationships with therelationship type Leading.
The key length of an entity type with storage anduse type 1 exceeds the maximum length of the enqueue key. Thiscauses 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

Procedure
Check whether you want to use the data model despite of the higher levelof locking. If applicable, modify the settings for the data element andthe related entity types so that the complete key has a maximum lengthof 111 characters (or 117 characters for entities without an edition).
