How to retrieve entity logical name using guid

(0) ShareShare
ReportReport
Posted on by Itz_Me_Ram 155

I have relationship like 

Account --> Appointment = 1:N

Distribution Office --> Appointment = 1:N

Appointment --> App Doc = 1:N

You can create an appointment either from Account or Distribution office. After appointment is created, an App doc is created. I need to display the contacts associated with either account or distribution office on App doc entity form.

I did an API call by passing the lookup attribute and got the regardingobjectid_value of the appointment (see below). Now i want to know the logical name of this regardingobjectid_value so that i will know if it created from account or distribution office.

var appid = window.parent.Xrm.Page.getAttribute("new_origmeeting").getValue()[0].id.toString();

req.open("GET", window.parent.Xrm.Page.context.getClientUrl() + "/api/data/v8.2/appointments(" + appid + ")?$select=_regardingobjectid_value", false);

How do i get the entity logical name by using regardingobjectid_value in javascript ??

    You will get logical name of Regarding Object Id in result set.

    Complete sample code will be

    var req = new XMLHttpRequest();

    req.open("GET", Xrm.Page.context.getClientUrl() + "/api/data/v8.1/appointments(3C81E020-A4CE-E511-80B9-005056B11FF6)?$select=_regardingobjectid_value", true);

    req.setRequestHeader("OData-MaxVersion", "4.0");

    req.setRequestHeader("OData-Version", "4.0");

    req.setRequestHeader("Accept", "application/json");

    req.setRequestHeader("Content-Type", "application/json; charset=utf-8");

    req.setRequestHeader("Prefer", "odata.include-annotations=\"*\"");

    req.onreadystatechange = function() {

       if (this.readyState === 4) {

           req.onreadystatechange = null;

           if (this.status === 200) {

               var result = JSON.parse(this.response);

               var _regardingobjectid_value = result["_regardingobjectid_value"];

               var _regardingobjectid_value_formatted = result["_regardingobjectid_value@OData.Community.Display.V1.FormattedValue"];

               var _regardingobjectid_value_lookuplogicalname = result["_regardingobjectid_value@Microsoft.Dynamics.CRM.lookuplogicalname"];

           } else {

               Xrm.Utility.alertDialog(this.statusText);

           }

       }

    };

    req.send();

    Make required changes in code, and highlighted line will give you logical name of regardingobjectid lookup.

    You need to add a request header to include that information to your request:

    setRequestHeader("Prefer", "odata.include-annotations=*")

    Then you will be able to get the response using

    _regardingobjectid_value@OData.Community.Display.V1.FormattedValue

    See the following blog article for inogic, which describes this in further detail:

    www.inogic.com/.../querying-data-in-microsoft-dynamics-crm-2016-using-web-api

    Hope this helps.

    Already tried that but it is returning undefined..This works fine when i create an appointment from contact entity but the issue is only with account entity.

    function RetriveAppointmentContact() {

               var req = new XMLHttpRequest();

               var appid = window.parent.Xrm.Page.getAttribute("new_origmeeting").getValue()[0].id.toString();

               appid = appid.replace('{', '');

               appid = appid.replace('}', '');

               req.open("GET", window.parent.Xrm.Page.context.getClientUrl() + "/api/data/v8.2/appointments(" + appid + ")?$select=_regardingobjectid_value", false);

               req.setRequestHeader("OData-MaxVersion", "4.0");

               req.setRequestHeader("OData-Version", "4.0");

               req.setRequestHeader("Accept", "application/json");

               req.setRequestHeader("Content-Type", "application/json; charset=utf-8");

               req.setRequestHeader("Prefer", "odata.include-annotations=\"*\"");

               req.onreadystatechange = function() {

                   if (this.readyState === 4) {

                       req.onreadystatechange = null;

                       if (this.status === 200) {

                           var result = JSON.parse(this.response);

                           var _regardingobjectid_value = result["_regardingobjectid_value"];

                           var _regardingobjectid_value_formatted = result["_regardingobjectid_value@OData.Community.Display.V1.FormattedValue"];

                           var _regardingobjectid_value_lookuplogicalname = result["_regardingobjectid_value@Microsoft.Dynamics.CRM.lookuplogicalname"];

                           GetAccount(_regardingobjectid_value);

                       } else {

                           Xrm.Utility.alertDialog(this.statusText);

                       }

                   }

               };

               req.send();

           }

    Appointment created via contact :

    {"@odata.context":"test.crm.dynamics.com/.../v8.2$metadata#appointments(_regardingobjectid_value)/$entity","@odata.etag":"W/\"598155\"","_regardingobjectid_value@OData.Community.Display.V1.FormattedValue":"Eli manning","_regardingobjectid_value@Microsoft.Dynamics.CRM.associatednavigationproperty":"regardingobjectid_contact_appointment","_regardingobjectid_value@Microsoft.Dynamics.CRM.lookuplogicalname":"contact","_regardingobjectid_value":"ee142714-61c5-e711-a950-000d3a34a108","activityid":"9c89632f-61c5-e711-a950-000d3a34a108"}
