Dynamics CRM : Retrieve multiple appointments for a systemuser

Question

I'm a trying to get all the appointments for a systemuser with a RetrieveMultiple method and a query expression. Example :

WhoAmIRequest userRequest = new WhoAmIRequest();
WhoAmIResponse userResponse = (WhoAmIResponse)_serviceProxy.Execute(userRequest);

QueryExpression qe = new QueryExpression();
qe.EntityName = "systemuser";

...
slos.RetrieveMultiple(qe);

Can I retrieve all the appointments of a systemuser (owner, organizer, required attendee, optional attendee) from a systemuser entity ?

Or do I have to retrieve all the appointments of the CRM and add conditions to know if the user is owner, organizer, required or optional attendee ?

Finally, I'm using SOAP Logger, is it the best way to generate SOAP request ?

Answer 1

With this Expression, I don't receive any appointments now :

QueryExpression qe = new QueryExpression
{
    EntityName = "appointment",
    ColumnSet = new ColumnSet("activityid", "subject", "scheduledstart", "scheduledend", "location", "description"),
    Criteria = new FilterExpression
    {
        FilterOperator = LogicalOperator.And,
        Conditions = 
        {
            new ConditionExpression("scheduledend", ConditionOperator.GreaterThan, startTime),
            new ConditionExpression("scheduledstart", ConditionOperator.LessThan, endTime)
         }
     },
     LinkEntities = 
     {
         new LinkEntity
         {
             LinkFromEntityName = "activitypointer",
             LinkFromAttributeName = "activityid",
             LinkToEntityName = "activityparty",
             LinkToAttributeName = "activityid",
             LinkCriteria = new FilterExpression
             {
                 FilterOperator = LogicalOperator.And,
                 Conditions = 
                 {
                     new ConditionExpression("participationtypemask", ConditionOperator.In, new int[] { 5, 6, 7, 9 }),
                     new ConditionExpression("partyid", ConditionOperator.Equal, userResponse.UserId)

                 }
             }
         },
         new LinkEntity
         {
             EntityAlias = "requiredattendees",
             Columns = new ColumnSet(false),
             JoinOperator = JoinOperator.Inner,
             LinkFromEntityName = "activitypointer",
             LinkFromAttributeName = "activityid",
             LinkToEntityName = "activityparty",
             LinkToAttributeName = "activityid",
             LinkCriteria = new FilterExpression
             {
                 Conditions = 
                 {
                     new ConditionExpression("participationtypemask", ConditionOperator.Equal, 5)

                 }
             },
             LinkEntities =
             {
                 new LinkEntity
                 {
                     EntityAlias = "contact",
                     Columns = new ColumnSet("fullname"),
                     JoinOperator = JoinOperator.Inner,
                     LinkFromEntityName = "activityparty",
                     LinkFromAttributeName = "activityid",
                     LinkToEntityName = "contact",
                     LinkToAttributeName = "contactid"
                 },
             }
         }
     }
 };

 qe.Distinct = true;

 slos.RetrieveMultiple(qe);

Answer 2

You'll need to use the relationship entity activitypointer between appointment and systemuser. As you'll see in my examples, this makes things a little complicated.

There are at least 2 possible ways to build your desired query:

1) As you already figured, you can filter appointments by systemuserid:

var qe = new QueryExpression
{
    EntityName = "appointment",
    ColumnSet = new ColumnSet("subject"),
    LinkEntities =
    {
        new LinkEntity
        {
            EntityAlias = "ap",
            JoinOperator = JoinOperator.Inner,
            Columns = new ColumnSet(false),
            LinkFromEntityName = "appointment",
            LinkFromAttributeName = "activityid",
            LinkToEntityName = "activityparty",
            LinkToAttributeName = "activityid",
            LinkCriteria = new FilterExpression
            {
                Conditions =
                {
                    new ConditionExpression("partyid", ConditionOperator.Equal, userid),
                },
            },
        },
    },
};

2) You can query the systemuser by systemuserid and add the appointments as a linked entity (like a JOIN in a sql query):

var qe2 = new QueryExpression
{
    EntityName = "systemuser",
    ColumnSet = new ColumnSet(false),
    LinkEntities =
    {
        new LinkEntity
        {
            EntityAlias = "ap",
            Columns = new ColumnSet(false),
            JoinOperator = JoinOperator.Inner,
            LinkFromEntityName = "systemuser",
            LinkFromAttributeName = "systemuserid",
            LinkToEntityName = "activityparty",
            LinkToAttributeName = "partyid",
            LinkEntities =
            {
                new LinkEntity
                {
                    EntityAlias = "a",
                    Columns = new ColumnSet("subject"),
                    JoinOperator = JoinOperator.Inner,
                    LinkFromEntityName = "activityparty",
                    LinkFromAttributeName = "activityid",
                    LinkToEntityName = "appointment",
                    LinkToAttributeName = "activityid",
                },
            },
        },
    },
    Criteria = new FilterExpression
    {
        Conditions =
        {
            new ConditionExpression("systemuserid", ConditionOperator.Equal, userid),
        },
    },
};

Concerning the filter for the participation role, you'll have to add a condition on the participationtypemask on the activitypointer:

// user is Organizer, Owner, required or optional Attendee
ConditionExpression("participationtypemask", ConditionOperator.In, new int[] { 5, 6, 7, 9 }),
