Due to Windows OS limitations on the number of characters in a file path, Model repository objects with long path and file names fail when you try to check them in. The Perforce error message reads "Submit aborted" and says the file path exceeds the internal length limit.
To work around this problem, limit the length of directory names in the path to the Perforce depot, and limit the length of project, folder, and object names in the Model repository. Shorter names in all instances help limit the total number of characters in the object path name.
Alternatively, you can install Informatica or the Perforce instance on non-Windows hosts that do not have this limitation.
