Salesforce Interview Questions

Groups are set of Users. They contain individual users, other groups, the users in the particular role, the users in a particular role plus all of the users below that role in the hierarchy. There are two types of groups. 1. Public Group             |--> Only Administrator can create public groups, they can be used by everyone in the Organization. 2. Personal Group        |--> Each user can create groups for their personal use. Public Groups: Public Groups are set of users and they are used in a  Sharing Rule Giving Access to Folders Email alerts Public groups made up of any combination of  Users Roles Roles and Subordinates Public Groups When the Public Groups are made up of roles or roles and subordinates, when a User is added or removed from the role, the public group membership is updated. Queues: Queues allow groups of users to manage a shared workload more effectively. A queue is a location where records can be routed to a wait processing b

* Report types allow us to build a frame work in the report builder from which users can create and customize Reports. * A reoprt type define the set of records and fields available to a report based on the relationships between a primary object and its related objects. * Salesforce provides a large range of pre-defined standard report types. 1. Account&contact --> Contains information about accounts and contacts. 2. Opportunities 3. Customer support (Report types regarding cases and solutions) 4. Lead 5. Campaigns 6. Activities 7. Administrative Report types 8. Price Books, Products and Asset report types * Custom Report Types  In addition to the standard report types, we can also create custom report types. Custom report types extend the types of reports from which all users in organization can create or update custom reports.   

A DashBoard shows the data from source reports(Summary reports, Matrix reports) as visual components, which can be charts, gauges, tables, or visualforce pages. * Each dashboard can have up to 20 components * Administrators control access to dashboards by stroing them in folders with certain visibility settings. * Dashboards folders can be public, hidden or restricted to groups, roles. If we have access to a folder, we can view its dashboards.

public class TasKcreation {     public TasKcreation(){         String Userid=UserInfo.getUserId();         Contact c=new Contact(lastname='asasaa111');         insert c;         Task newTask = new Task(Description = 'Survey Transaction',                                         Priority = 'Normal',                                          Status = 'Inbound Email',                                          Subject = 'Other',                                          IsReminderSet = true,                                          ReminderDateTime = System.now()+1,                                          WhoId = c.id,                                         OwnerId=Userid);                              insert newTask;     } }

Scenario:  Using Trigger share a record when record insert or update In trigger Call the Apex class  public class ShareRule4 {     public Static void afterInsert(List<Case> c){         List<CaseShare> cShare=new List<CaseShare>();         User u=[select Id from User where alias='aaxis'];         for(Case cs:c){             if(cs.Status=='New'){                 CaseShare cshr=new CaseShare();                 cshr.CaseAccessLevel='read';                 cshr.CaseId=cs.id;                 cshr.UserOrGroupId=u.id;                 cshr.RowCause='manual';                 cShare.add(cshr);             }         }         insert cShare;     } } trigger ShareRule4 on Case (after insert, after update) {     ShareRule4 s=new ShareRule4();     ShareRule4.afterInsert(trigger.new); }

Scenario:   Whenever a new record is create or update, that record is shared to particular user trigger ShareRule2 on Account (after insert, after update) {     List<AccountShare> accShare=new List<AccountShare>();     user u=[select id from User where alias='aaxis'];     for(Account a:trigger.new){         if(a.Active__c=='yes'){         AccountShare accShr=new AccountShare();         accShr.AccountAccessLevel='read';         accShr.AccountId=a.id;         accShr.ContactAccessLevel='read';         accShr.CaseAccessLevel='read';         accShr.OpportunityAccessLevel='read';         accShr.RowCause='manual';         accShr.UserOrGroupId=u.id;         accShare.add(accShr);          }          }     insert accShare; } 

Scenario:  Share the Opportunity record whose is closed won with a user trigger SharingRules on Opportunity (after update, after insert) {     list<OpportunityShare> opshare=new list<OpportunityShare>();     user u=[select id from user where alias='aaxis'];     //List<opportunity> lop=[select id from Opportunity where ]     for(opportunity op:trigger.new){         if(op.stagename=='Closed Won'){             OpportunityShare opshr=new OpportunityShare();             opshr.OpportunityId=op.id;             opshr.OpportunityAccessLevel= 'read';             opshr.UserOrGroupId=u.id;             opshr.RowCause='manual';             opshare.add(opshr);         }     }

Controller: A visualforce controller is a set of instructions that specify what happens when a user interacts with the components specified  in associated visualforce markup, such as when a user clicks a button or link. Controller also provide access to the data that should be displayed in a page, and can modify component behavior StandardController: A standardcontroller consist of the same functionality and logic that is used for a standard salesforce page. for eample , if you use the standar account controller, clicking a save button in a visualforce page results in the same behaviour as clicking save on a Standard Account detail page. <apex:page standardController="Account" > Custom Controller: A custom Controller is a class written in Apex that implements all of a page's logic. If we use a custom controller, we can define new navigation elements or behaviour, but we must also reimplement any functionality that was already provided in a standard

public class FutureClass {     @future     public static void callme(ID myId){         GroupMember gmr=new GroupMember();         gmr.GroupId=myId;         gmr.UserOrGroupId=userInfo.getUserId();         insert gmr;     } } public class FutureExample {     public void show(){         Account ac=new Account(Name='FutureClassEx2');         insert ac;         Group newGroup=new Group();         newGroup.Name=ac.name;         newGroup.DoesIncludeBosses=false;         insert newGroup;         FutureClass.callme(newGroup.Id);     } }

1. These are asynchronous jobs. 2. To implement the operation of queueable, we have to implement the interface of Queueable. 3. Any class that implements Queueable Interface has to define execute method. 4. The job that need to be implemented has to be designed with in execute method. 5. If you want to schedule the jobs we have to use System.enqueueJob. Ex:  public class QueueExample implements Queueable{     public void execute(QueueableContext context){        Account a=new Account(Name='AccName', Phone =' 12345');             insert a;     } } in Debug  System.enqueueJob(new QueueExample()); QueueExample queEx=new QueueExample(); system.enqueuejob(queEx);

What is madatory while creating User, Role or Profile? A: It's profile. 5. Who can run reports? A: User with permission "Run Report" and access to report folder can only run the report. 6.
