Thank you for kind reply sir,

I will try your 1st point suggestion.

In the small field proton simulation, I am using the same geometry parameters of both Geant4 10.02.p02 and Geant4 10.04.p02 versions. But the new version Geant4 10.04 the fluence result showing error (like ripple) in dose entrance. 
I didnít change any parameters in G4EmStandardPhysics_option4. 
In the attachment file, I mentioned the Energy, phantom size, field size, detector size, and resolution. I have the same problem for other Energies and other fields.

G4EmStandardPhysics_option3 also showing the same error for a small field.

I attached PDF file for both Geant4 versions & options results.
