Why I am not able to find list of Person Account fields in Field Level Security (FLS) settings when navigated to fields on Account Object.

Field Level Security (FLS) of Person Account fields ar controlled by Contact Fields. So, if you want to setup FLS of Person Account Fields navigate to fields of Contact and it will be reflected on Person Account

How do you import Converted Lead into Salesforce from Legacy System

How do you import Converted Lead into Salesforce from Legacy System

Fields we need for importing converted leads are “ISCONVERTED” , “CONVERTEDCONTACTID” , “CONVERTEDOPPORTUNITYID” and “CONVERTEDACCOUNTID“.

Step 1 : As above fields are not editable, we have to contact Salesforce Support to enable Audit fields. Enabling Audit fields means we can edit few Readonly fields like created date and above lead fields.

Step 2 : Import Account, Contact and Opportunity from Legacy system to Salesforce.

Step 3 : If you imported account, contact and opportunity in Step 2, Salesforce automatically generates Unique ID. We need that unique Id to insert Converted Lead. So Export Account, Contact and Opportunity, which is inserted in Step 2 from legacy System.

Step 4 : Create CSV File with All lead information with ISCONVERTED=TRUE and CONVERTEDCONTACTID, CONVERTEDOPPORTUNITYID, CONVERTEDACCOUNTID. CONVERTEDCONTACTID, CONVERTEDOPPORTUNITYID and CONVERTEDACCOUNTID should correspond to Ids generated by Salesforce for Contact, Opportunity and Account which will be related to converted lead.

Step 5 : Once CSV is properly created with all required Data, Insert it using DataLoader.

Note : We cannot convert existing lead using this process. Leads must be inserted with these four fields. If you try to update lead it will not give you option to edit above fields 

After Data Export using DataLoader, Some time it appears that data is on New Line (Carriage Return) when we open CSV file in Microsoft Excel. For example , Address Data separated on different lines. How can we override this problem

After Data Export using DataLoader, Some time it appears that data is on New Line (Carriage Return) when we open CSV file in Microsoft Excel. For example , Address Data separated on different lines. How can we override this problem

Excel does all sorts of “useful” things when it opens a CSV file. It will re-format dates, strip leading zeros, corrupt record IDs (if you have them in your report), and as explained it will also break line. Best way as per my experience till date is, Upload document to Google Drive. Export document back from Google drive as Excel.

Please post comment in this article if you know any other working way.

  

How you can use Datetime field as a criteria in SOQL Query

How you can use Datetime field as a criteria in SOQL Query

We cannot use Datetime as condition in Where Clause in between single Quotes.

You can do something like this ,

WHERE CreatedDate > 2005-10-08T00:00:00Z

Or, you can also use Date Literals like

WHERE CreatedDate > YESTERDAY

For more information on date formats and more literal values, check this URL.

Sample:

soql += ' and Name LIKE \''+String.escapeSingleQuotes(key1)+'%\''; - not required single quote like this.

How to use Datetime in Dynamic SOQL Query in Salesforce

This error is because of wrong construction of Dynamic Query with Datetime. following code snippet will give idea on how to construct dynamic query for Datetime ?

//format the datetime to make it Dynamic Soql ready

String formatedDt = cutOffDateTime.format('yyyy-MM-dd\'T\'HH:mm:ss\'Z\'');

String sql = 'SELECT  a.Id  FROM  Agents_Answer__c a    WHERE  a.Agents_Test_Result__r.Agent_Name__r.IsActive__c = false AND  LastModifiedDate < '+ formatedDt ;

Where, “cutOffDateTime” is variable of datetime type. 

Can we mass delete reports using Apex (Anonymous Apex)

Can we mass delete reports using Apex (Anonymous Apex)

Salesforce has not exposed any API for Reports. So best way is :

Move all reports needs to delete in new folder.

Inform everyone that reports will be deleted after some time may be 30 days.

Import your reports folder in Eclipse including all reports to be deleted and then delete the the reports folder in eclipse. It will delete all the reports at once.

  

In below code snippet , What is your observation and what is going wrong ? * trigger TestBeforeDelete on Lead (before Delete) { for(Lead l : Trigger.Old) { l.addError('error'); } String msgBody = 'Test Email'; String Subject = 'Test from Cogni Force on Lead'; Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage(); String[] toAddresses = new String[] {'abc@gmail.com'}; mail.setToAddresses(toAddresses); mail.setReplyTo('abc@gmail.com'); mail.setSenderDisplayName('Cogniforce Test Simulator'); mail.setSubject(Subject); mail.setPlainTextBody(msgBody); mail.setHTMLBody(msgBody); Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail }); }

In below code snippet , What is your observation and what is going wrong ? *

trigger TestBeforeDelete on Lead (before Delete) {

        for(Lead l : Trigger.Old)

        {

            l.addError('error');

        }

        String msgBody = 'Test Email';

        String Subject = 'Test from Cogni Force on Lead';

        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();

        String[] toAddresses = new String[] {'abc@gmail.com'};

        mail.setToAddresses(toAddresses);

        mail.setReplyTo('abc@gmail.com');

        mail.setSenderDisplayName('Cogniforce Test Simulator');

        mail.setSubject(Subject);

        mail.setPlainTextBody(msgBody);

        mail.setHTMLBody(msgBody);

        Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });

}

It will not send any email. Because “adderror” prevents all transactions from committing including emails

Why are Visualforce pages served from a different domain

Why are Visualforce pages served from a different domain

If we see carefully, all our Visualforce pages are served like “c.YOURSERVER.visual.force.com/apex/YOURPAGENAME” ,

And because of this most of time we run into Same-Origin Policy error in Javascripyt if we try to access parent page from Iframe. Following reason is explained by one of the evangelist of Salesforce:

“The move to separate domains has one very specific purpose: leverage the browser security model (same domain policy) to protect our customers and the salesforce.com service from cross site scripting and cross site request forgery attacks.

Moving to the serving pages from separate domains is a critical component of our ongoing commitment to insure the highest level of security and availability for everyone.

In the world where everything is served from the same domain any custom page that you visit had full access to any other page in your org and also any page served from salesforce.com itself. This included potentially malicious code that was installed as part of a force.com package.”

Sometimes while deleting record it gives error “Object cannot be Deleted”. What is the reason for this kind of error

Sometimes while deleting record it gives error “Object cannot be Deleted”. What is the reason for this kind of error

This is generic error message prompted by Salesforce many times, which is not well informative. To get informative message, we can try to delete same record in “Developer Console”. In Developer Console Debug log, we will get exact error message.

Example : Lets say there is one record which is parent of more than 2000 records and grand parent of 5000 records. In such scenario from developer console it gives error something like “record cannot be deleted because it has many associated objects” However in User Interface, it will just display that “Object cannot be deleted.“ 

Explain few considerations for @Future annotation in Apex

Explain few considerations for @Future annotation in Apex

Method must be static

Cannot return anything ( Only Void )

To test @future methods, you should use startTest and stopTest to make it synchromouse inside Test class.

Parameter to @future method can only be primitive or collection of primitive data type.

Cannot be used inside VF in Constructor, Set or Get methods.

Explain Considerations for Static keyword in Apex

Explain Considerations for Static keyword in Apex

Apex classes cannot be static.

Static allowed only in outer class.

Static variables not transferred as a part of View State.

Static variables and static block runs in order in which they are written in class.

Static variables are static only in scope of request.

What is difference between public and global class in Apex

What is difference between public and global class in Apex

Public class can be accessed within application or namespace. This is not exactly like public modifier in Java.

Global class visible everywhere , any application or namespace. WebService must be declared as Global and which can be accessed inside Javascript also. It is like public modifier in Java.

global class MySchedulableClass implements Schedulable {} - schedular class

global class UpdateController {

webService static string updateEnable(List<Id> accId){}

} - javascript remoting

global class MyWebService {

    webService static Id makeContact(String lastName, Account a) {

        Contact c = new Contact(lastName = 'Weissman', AccountId = a.Id);

        insert c;

        return c.id;

    }

} 

How can you call Apex class using Javascript ? Give Example

 How can you call Apex class using Javascript ? Give Example

global class myClass {

                webService static Id makeContact (String lastName, Account a) {

                                Contact c = new Contact(LastName = lastName, AccountId = a.Id);

                                Insert c;

                                return c.id;

                }

}

we can execute above method from javascript like :

var account = sforce.sObject("Account");

var id = sforce.apex.execute("myClass“ , "makeContact",

{lastName:"Smith", a:account});

To call a webService method with no parameters, use {} as the third parameter for sforce.apex.execute .

Also, you can use the following line to display a popup window with debugging information:

sforce.debug.trace=true;

What are few Considerations about Trigger

What are few Considerations about Trigger

upsert triggers fire both before and after insert or before and after update triggers as appropriate.

merge triggers fire both before and after delete triggers for the losing records and before update triggers for the winning record only.

Triggers that execute after a record has been undeleted only work with specific objects.

Field history is not recorded until the end of a trigger. If you query field history in a trigger, you will not see any history for the current transaction.

You can only use the webService keyword in a trigger when it is in a method defined as asynchronous; that is, when the method is defined with the @future keyword.

A trigger invoked by an insert, delete, or update of a recurring event or recurring task results in a runtime error when the trigger is called in bulk from the Force.com API.

Merge trigger doesn’t fire there own trigger instead they fire delete and update of loosing and winning records respectively 

What are few limitations (points to remember) of Savepoint or Transaction Control in Apex

What are few limitations (points to remember) of Savepoint or Transaction Control in Apex

Each savepoint you set counts against the governor limit for DML statements.

Static variables are not reverted during a rollback. If you try to run the trigger again, the static variables retain the values from the first run.

Each rollback counts against the governor limit for DML statements. You will receive a Runtime error if you try to rollback the database additional times.

The ID on an sObject inserted after setting a savepoint is not cleared after a rollback.

  

If you set more than one savepoint, then roll back to a savepoint that is not the last savepoint you generated, What will happen to later savepoint variables

If you set more than one savepoint, then roll back to a savepoint that is not the last savepoint you generated, What will happen to later savepoint variables

if you generated savepoint SP1 first, savepoint SP2 after that, and then you rolled back to SP1, the variable SP2 would no longer be valid. You will receive a runtime error if you try to use it.

How to handle comma within field while uploading using DataLoader

How to handle comma within field while uploading using DataLoader

Data Loader cannot handle this implicitly because there is no logical path to follow. In case your Data Loader CSV file for import will contain commas for any of the field content, you will have to enclose the contents within double quotation marks ” “. Data Loader will be able to handle this.

For example :

Column_1__c,Column_2__c,Column_3__c

Shiva,"Jitendra, Minal",Soft

If you are creating the import CSV in Excel, the quotation marks will be inserted automatically by Excel whenever a comma is detected in any cell – Saving the CSV in Excel and opening the same in Notepad reveals the enclosing quotation marks for cells containing commas.

What is the difference between “apex:dataTable” and “apex:pageBlockTable” components in Visualforce

What is the difference between “apex:dataTable” and “apex:pageBlockTable” components in Visualforce

Both component is used to render data in tabular format. dataTable will render records in simple HTML table format whereas the “pageBlockTable” possess default look and feel of salesforce standard CSS and must be written inside “apex:pageBlock” componet.

You can read more here.

PageBlockTable:

PageBlockTable should be defined inside pageblock or pageblocksection.

PageBlockTable uses standard styles sheets to design a visualpage.

It has the  required attribute "value".

Column headers  will be displayed automatically.

DataTable:

No need to write inside pageblock or pageblocksection.

There is no required value.

The  data can be displayed using  custom style sheets.

we need to specify column headers explicitly.

Javascript Remoting, ActionFunction, ActionSupport, ActionPoller.

var Attachrecords = sforce.connection.query(strQuery); 

var result = sforce.apex.execute("UpdateController", "updateEnable",{accId: accountId}); 

Explain ActionFunction, ActionSupport and ActionPoller in Visualforce

Explain ActionFunction, ActionSupport and ActionPoller in Visualforce

apex:ActionFunction : This component helps to envoke AJAX request (Call Controllers method) directly from Javascript method. It must be child of apex:form. Read here – www.salesforce.com/us/developer/docs/pages/Content/pages_compref_actionFunction.htm

<apex:actionFunction name="sendEmail" action="{!sendEmailFunction}"></apex:actionFunction>

apex:ActionSupport : This component adds Ajax request to any other Visualforce component. Example : Commandlink button has inbuilt AJAX functionality however few components like OutputPanel does not have inbuilt AJAX capabilities. So with the help of this component, we can enable AJAX. Read more here.

<apex:outputpanel id="counter">

<apex:outputText value="Click Me!: {!count}"/>

<apex:actionSupport event="onclick"  action="{!incrementCounter}"  rerender="counter" status="counterStatus"/>

</apex:outputpanel>

apex:ActionPoller : This is timer component which can send AJAX request on pre-defined interval. Minimum interval is 5 sec and default is 60 sec.

<apex:actionPoller action="{!incrementCounter}" rerender="counter" status="counterStatus" interval="50" />

Similarities:

Both action support and function can be used to call a controller method using an AJAX request.

Differences:

1. Action function can call the controller method from java script.

2. Action support adds AJAX support to another visualforce component and then call the controller method.

    for example:

     <apex:outputpanel id="outptpnl">

             <apex:outputText value="click here"/>

         <apex:actionSupport event="onclick" action="{!controllerMethodName}"  rerender="pgblck" />

     </apex:outputpanel>   

Here action support adds AJAX to output panel, so once you click on output panel controller method will be called.

3. Action function cannot add AJAX support to another component. But from a particular component which has AJAX support(onclick, onblur etc) action function can be called to call the controller method.

Example:

 <apex:actionFunction name="myactionfun"  action="{!actionFunMethod}" reRender="outptText"/>

 <apex:inputcheckbox onclick="myactionfun" />

In this example onlick of input checkbox "myactionfun" action function is called from where controller method "actionFunMethod" gets called.

Apart from this, the main difference between the "two" action support and action function is that, the action function can also be called from java script.

Example:

<apex:actionFunction name="myactionfun"  action="{!actionFunMethod}" reRender="outptText"/>

 <apex:inputcheckbox onclick="myJavaMethod()" />

<script>

   function myJavaMethod(){

     myactionfun();// this call the action function

  }

  </script>

When loading data into date fields such as Opportunity Close Date using the Data Loader, the date displayed in the application is sometimes one day earlier than the date in the file. What may be the reason and solution

When loading data into date fields such as Opportunity Close Date using the Data Loader, the date displayed in the application is sometimes one day earlier than the date in the file. What may be the reason and solution

The reason for this is that fields such as Close Date are actually date/time fields. When a date is loaded without specifying the time, the time is defaulted to 00:00 – midnight. When another user is in a time zone which is behind the current user’s time zone, the date will show on the previous day. For example:

20 August 2008 00:00 in Paris is 19 August 2008 23:00 in London

Similar issues can arise when daylight savings time begins or ends.

Two simple solutions to this are:

1) Specify a time as well as a date when loading dates using the Data Loader.

or

2) Switch your PC’s time zone to Hawaiian time before starting up the Data Loader.

  

Let’s say we have to update the same record in After Trigger context. Is there any way or workaround

Let’s say we have to update the same record in After Trigger context. Is there any way or workaround

If we create a new instance of an SObject in the Apex Trigger in memory using the Id of the newly created record as provided in the After Trigger context, we can perform an Update DML statement and not get a read only error. This is because in Apex, the SObject is seen as a new reference (even though the records have the same SFDC ID) and therefore is eligible for DML operations. The below snippet of code illustrated this working and not working.

List<Contact> originals = new List<Contact>();

if(mirrorResultMap.values().size() > 0)

{

                for(Contact origContact : contactRecs.values())

                {

                                Contact mirrorContact = mirrorResultMap.get(origContact.Id);

                                //origContact.Linked_Contact__c = mirrorContact.Id; //Link the Original Record tot he Mirror Record WILL FAIL

                                Contact origContactUpdate = new Contact(Id=origContact.Id, Linked_Contact__c = mirrorContact.Id); //This will WORK

                                originals.add(origContactUpdate);

                }

                //update contactRecs.values(); //Update the Records -> THIS WILL FAIL AS ITS ORIGINAL RECORDS IN MEMORY

                update originals;

}
