I have an issue checking-out files in FileNet P8. It is possible for me to perform a checkout over documents with class "Document". Nevertheless, for any document from another class, the systems keeps telling me that the operation is not permitted.
On which level can I change this? Is it a basic document class property or is it over the Object Store parameters?
It is defined on class level if specific class is versionable. You should check if versioning is enabled for the class you work with:
