SAP Error Message - Details

• Message type: E = Error

• Message class: ARS_CMP_ATC - API Release: Compatibility Checks – ATC Messages

• Message number: 040

• Message text: Object was changed incompatibly regarding configuration content (C3).

What causes this issue?

Incompatible changes were detected in a development object which was
released as stable persistence for configuration content (compatibility
contract C3).

System Response

Each released API is checked for incompatible changes between releases
depending on the assigned compatibility contract. Those checks comprise
of <ZK>basic checks </>(e.g. detection of deleted elements) and
<ZK>domain-specific checks </>(e.g. detection of annotation changes in
CDS views) by different application components.

How to fix this error?

Read the details of the check message, describing an incompatible change
in a development object which was released as API.
<ZH>Note</>: If the checked development object is a package, the check
messages refer to objects which were formerly contained in this package
but were deleted although they have been released as APIs.
Undo this incompatible change by restoring the affected part of the API
in the way it was previously shipped to the customer.
Example
A field was removed from a released database table. As a result,
customer-specific configuration content which was created and exported
before the incompatible change can no longer be imported consistently.
<ZK>Check message</>: Component <FieldName> must not be removed.
<ZK>Remedy</>: Add this field to the database table again, using the
same data type as before.
