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

SAP Error Message - Details

• 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.

• What is the cause and solution for SAP error message CRM_EVENT001 - Structures for the old/new values transferred do not correspond ?

  The SAP error message CRM_EVENT001 indicates that there is a mismatch between the structures of the old and new values being transferred in a CRM (Customer Relationship Management) context. This error typically occurs during data updates or changes when the system expects certain fields or structures to match but finds discrepancies.
  Cause:
  
  Data Structure Mismatch: The most common cause is that the data structure of the old values does not match the structure of the new values. This can happen if there have been changes in the data model or if the data being processed is not formatted correctly.
  Custom Enhancements: If there are custom enhancements or modifications in the CRM system, they might lead to inconsistencies in the expected data structures.

  Check Data Structures: Review the data structures for both the old and new values. Ensure that they match in terms of field names, types, and lengths.
