Hi,
I don't know what happened but one model in my environment suddenly can't be modified anymore. It does get below error message:
Necessary data are missing
Creating a new version or publishing this version (if not already published) is not possible. Some essential data required for editing this version has been deleted from the environment. If the model has already been published, it can still be used. Please also see attached screenshot.
Has someone ever seen this error and what could it be?
