I would like to know what the difference is between the following sentences:
- A PM (project manager) can only track so many items
- Only PM can track so many items
Is the first sentence grammatically correct ?

The first sentence using "can only" is expressing a limitation of the PM. It says that the PM has an upper limit to the number of items he can track.
The second sentence using "Only a PM can" is expressing a unique capability of the PM. It says that nobody else except a PM is capable of tracking so many items.
