Not using any shift files in the model but when the model is simulated the following errors are received.
A space is in one of the shift file boxes on an activity, resource or in the default file location boxes under Simulation / Options.
Check all your activity and resource Shift tabs for a space in the Shift File box. Also check the Simulation / Options / File tab. The default activity or shift options could have a space in the File Name box.
