Recommendation refers to an action which is advisory in nature rather than one having any binding effect. 

Recommendation is a legal instrument that encourages those to whom it is addressed to act in a particular way without being binding on them. A Recommendation enables the Commission
(or the Council) to establish non-binding rules for the Member States or, in certain cases, Union citizens.
