Transaction Log Details of an Entity using MDS API

Hi Team,

Does Transaction Log Details of an Entity available in SQL 2012 ?

If yes,guide me in achieving it using MDS API.

Another question For particular Member of the entity how to set the User ID in searchCriteria,

I tried like this way:

TransactionSearchCriteria sc  = new TransactionSearchCriteria();
sc.ModelId = new Identifier{ Name = mymodelname};
sc.EntityId = new Identifier{ Name = myentiytname};
sc.UserId = new Identifier{Name = myusername};
sc.VersionId = new Identifier {Name = myversion};

transactionrequestobj.TransactionCriteria = sc;
transactionresponseobj = ServiceProxy.TransactionGet(transacreqobj);
