Posted on by Victor Onyebuchi 410

Hello,

   I am trying to get the current logged in user or create a user and assign it to the look up field using client services in a windows form. But it come up with the error -"An Error Occurred". My code can be seen below:

            //creating a user
            SystemUser systemUser = new SystemUser();
            systemUser.FirstName = "Victor";
            systemUser.LastName = "*******";
            Guid systemID = (Guid)Service().Create(systemUser);

             systemUser = (SystemUser)Service().Retrieve(systemUser.LogicalName, systemID, new Microsoft.Xrm.Sdk.Query.ColumnSet("fullname"));
        
            //this field is a lookup field to User. Assigned to the user created above
            clinic.new_ClinicCoordinator = new CrmEntityReference (systemUser.LogicalName, systemID);

Thanks in advance people.

    Hi,

    Is this user already part of the Office 365 ?? because in case crm online users are synchronised from office 365 as soon as it is added and licence is configured. If not then you need to add this user to office 365 first, something like this: stackoverflow.com/.../create-user-accounts-in-office-365-using-c-net-code-dynamically

    Or you can use the powershell like this: community.dynamics.com/.../104204

    Hope it will help !!

    Hi Victor,

    As mentioned above, you cannot create user for CRM online directly using CRM SDK. You need to create users in O365 and assign licence. Once the license is assign you user will be created in your CRM organization.

    Alternatively, you could use the below code for existing users-

    For currently logged in user use WhoAmIRequest message-

    =========================

    var userId = ((WhoAmIResponse)service.Execute(new WhoAmIRequest())).UserId;

    var userRef = new EntityReference("systemuser", userId);

    =========================

    To retrieve a different user by username

    =============================

    QueryExpression userQuery = new QueryExpression

                   {

                       EntityName = "systemuser",

                       ColumnSet = new ColumnSet("systemuserid"),

                       Criteria = { Conditions = { new ConditionExpression("domainname", ConditionOperator.Equal, "username@testorg.onmicrosoft.com") } }

                   };

                   var userResults = service.RetrieveMultiple(userQuery);

                   var retrievedUser = userResults.Entities.FirstOrDefault();

                   var userRef = retrievedUser.ToEntityReference();

    =============================

    Once you get the user reference, you can then set the user referenc directly to your other code. E.g.

    clinic.new_ClinicCoordinator = userRef ;

    Hope this helps.
