Do keep in mind that merely having a Schengen visa in your possession does not confer you with an automatic right to enter the Schengen Area.
You might be asked to produce additional documents at the external border. Documents might be required justifying the purpose of stay and conditions attached to your stay; as well as for proving that either you have sufficient means of subsistence with you or are able to arrange the same lawfully. The means of subsistence should cover your intended stay as well as return to home country or to a third state into which there is a certainty of your being admitted.
Travel insurance policy: A document which proves that you have travel health insurance coverage for the whole of the Schengen zone, with a minimum coverage of EUR 30,000 in the event of any medical emergency, such as illnesses, injuries and even repatriation in the event of death.
Proof of sufficient funds: Evidence that you have enough money to financially support yourself during your stay in the Schengen area.
