What do we do when we get an error message that says, “The file you are attempting to save is NOT compatible with the Central File…”
This error is followed by:
Usually, one gets this error is the Central file was ‘saved over’ with another file. It does not sound plausible. But it happens!
The best course of action would be STOP working on the local file and create a new local file. Most probably, the one would lose the work since the last Save to Central.
Trying to copy from the old local and paste into the new local can work if the new edits are copy/paste friendly. Changes in schedules can be copied using scripts.
