How To Fix USMD2349 - Change of data model may lead to corrupt change request data

SAP Error Message - Details

• Message type: E = Error

• Message class: USMD2 - Master Data: UI Modeling

• Message number: 349

• Message text: Change of data model may lead to corrupt change request data

What causes this issue?

You have changed the data model of the change request type.

System Response

If there are no change requests of this change request type in the MDG
system landscape the data model can be changed without negative impact.
If the new data model is compatible (e.g. a copy of the former data
model with the same entity types) with the former data model, the change
request data of existing change requests remain consistent.
If the data model of this change request type has been changed and the
new data model is not compatible with the former data model, and change
requests of this change request type already exist in the MDG system
landscape, all of these change requests are corrupt.
The object list as well as inactive data of such a change request do not
match the assigned entities anymore. It is not possible to delete such a
change request. Change request data and the object list from finalized
change requests are also corrupt.

How to fix this error?

You can ignore this message if the data model is compatible with the
former data model or if no change request has yet been created of that
change request type in the MDG system landscape yet.
Do not make any other changes to the data model of that change request
type.
