How To Fix CRM_EVENT001 - Structures for the old/new values transferred do not correspond

CRM_EVENT001 - Overview

• Message type: E = Error

• Message class: CRM_EVENT - Message Class for Event Handler in CRM Transaction

• Message number: 001

• Message text: Structures for the old/new values transferred do not correspond

What causes this issue?

The Event Handler accepts and processes the events that are triggered
by the programs running during the processing of a CRM transaction. Two
fields belong to the event attributes. The fields can contain different
data and their statuses often mirror each other both before and after a
change. The structures for both of these old/new fields must be
identical, otherwise runtime errors will occur in the subsequent
programs.
In this case, the event &V2& was triggered for the object &V1&
(attribute &V3&). The old/new values transferred to the Event Handler
at this point have a different structure.
