Hi Manpreet

Trigger.old

Returns a list of the old versions of the sObject records. Note that this sObject list is only available in update and delete triggers.

We normally use it when we :

Need to check if any field is update in the DML Activity then do another update, like if account name gets changed then update related opportunity name

Hope it may helps

Hi Suraj

You can  load 50,000 to 5,000,000 records by using Data Loader. If you need to load more than 5,000,000 records, i recommend you work with a Salesforce.com partner.

Hope it may help you

Hello Suraj

According to the docs, Trigger.new returns a list, which are ordered, and Trigger.newMap returns a map - which are unordered. The docs specifically state you should not rely on the ordering of a map's elements.

What to use depends on what you're doing - if you have an ID of an object you need to do something with, using the map makes more sense as you can use newMap.get(). Otherwise you'd have to loop over all the elements in Trigger.new and look for a matching ID. Similarly, if you have multiple loops over each item the trigger is operating on, the list returned by Trigger.new may be the better bet.

suppose you have a custom object Custom_obj__c

Trigger.New means it is a List<Custom_obj__c>

and

Trigger.NewMap means it is a map<Id, Custom_obj__c>
In before insert context your Trigger.NewMap always be null because in before context records is not submitted to database so Id is not generated that's why in before insert we don't useTrigger.NewMap

But in After insert Id is generated so We can use Trigger.NewMap

In case of before and After update since id is already generated in Insert event.

SO we can use Trigger.NewMap in before and After update

Hi Suraj

Salesforce Order of Execution: When you save a record with an insert, update, or upsert statement, Salesforce performs the following events in order.

"Before Salesforce executes these events on the server, the browser runs JavaScript validation if the record contains any dependent picklist fields. The validation limits each dependent picklist field to its available values. No other validation occurs on the client side."

On the server, Salesforce:Loads the original record from the database or initializes the record for an upsert statement.
Loads the new record field values from the request and overwrites the old values.If the request came from a standard UI edit page, Salesforce runs system validation to check the record for:Compliance with layout-specific rules
Required values at the layout level and field-definition level
Valid field formats
Maximum field length
When the request comes from other sources, such as an Apex application or a SOAP API call, Salesforce validates only the foreign keys. Prior to executing a trigger, Salesforce verifies that any custom foreign keys do not refer to the object itself.Salesforce runs user-defined validation rules if multiline items were created, such as quote line items and opportunity line items.
Executes all before triggers.
Runs most system validation steps again, such as verifying that all required fields have a non-null value, and runs any user-defined validation rules. The only system validation that Salesforce doesn't run a second time (when the request comes from a standard UI edit page) is the enforcement of layout-specific rules.
Executes duplicate rules. If the duplicate rule identifies the record as a duplicate and uses the block action, the record is not saved and no further steps, such as after triggers and workflow rules, are taken.
Saves the record to the database, but doesn't commit yet.
Executes all after triggers.
Executes assignment rules.
Executes auto-response rules.
Executes workflow rules.
If there are workflow field updates, updates the record again.
If the record was updated with workflow field updates, fires before update triggers and after update triggers one more time (and only one more time), in addition to standard validations. Custom validation rules, duplicate rules, and escalation rules are not run again.
Executes processes.If there are workflow flow triggers, executes the flows.

The pilot program for flow trigger workflow actions is closed. If you've already enabled the pilot in your org, you can continue to create and edit flow trigger workflow actions. If you didn't enable the pilot in your org, use the Flows action in Process Builder instead.
Executes escalation rules.
Executes entitlement rules.
If the record contains a roll-up summary field or is part of a cross-object workflow, performs calculations and updates the roll-up summary field in the parent record. Parent record goes through save procedure.
If the parent record is updated, and a grandparent record contains a roll-up summary field or is part of a cross-object workflow, performs calculations and updates the roll-up summary field in the grandparent record. Grandparent record goes through save procedure.
Executes Criteria Based Sharing evaluation.
Commits all DML operations to the database.
Executes post-commit logic, such as sending email.

Hi Suraj

Salesforce provides a WSDL (Web Service Description Language) file. They are called "Enterprise WSDL" and "Partner WSDL". A WSDL is an XML-document that contains a standardized description on how to communicate using a web service (the Salesforce API is exposed as a web service). The WSDL is used by developers to aid in the creation of Salesforce integration pieces. A typical process involves using the Development Environment (eg, Eclipse for Java, or Visual Studio for .Net) to consume the WSDL and generate classes that are then referenced in the integration.

The primary differences between the two WSDL that we provide are:

Enterprise WSDL:
a) The Enterprise WSDL is strongly typed.
b) The Enterprise WSDL is tied (bound) to a specific configuration of Salesforce (ie. a specific organization's Salesforce configuration).
c) The Enterprise WSDL changes if modifications (e.g custom fields or custom objects) are made to an organization's Salesforce configuration.

For the reasons outlined above, the Enterprise WSDL is intended primarily for Customers.

Partner WSDL:
a) The Partner WSDL is loosely typed.
b) The Partner WSDL can be used to reflect against/interrogate any configuration of Salesforce (ie. any organization's Salesforce configuration).
c) The Partner WSDL is static and hence does not change if modifications are made to an organization's Salesforce configuration.

For the reasons outlined above, the Partner WSDL is intended primarily for Partners.

To download a WSDL file when logged into Salesforce:

1. Click Setup | Customize | Develop | API

2. Click the link to download the appropriate WSDL.

3. Save the file locally, giving the file a ".wsdl" extension.

Hi Manpreet

Custom settings are similar to custom objects and enable application developers to create custom sets of data, as well as create and associate custom data for an organization, profile, or specific user. All custom settings data is exposed in the application cache, which enables efficient access without the cost of repeated queries to the database. This data can then be used by formula fields, validation rules, flows, Apex, and the SOAP API.

There are two types of custom settings:

List Custom Settings
A type of custom setting that provides a reusable set of static data that can be accessed across your organization. If you use a particular set of data frequently within your application, putting that data in a list custom setting streamlines access to it. Data in list settings does not vary with profile or user, but is available organization-wide. Examples of list data include two-letter state abbreviations, international dialing prefixes, and catalog numbers for products. Because the data is cached, access is low-cost and efficient: you don't have to use SOQL queries that count against your governor limits.

Hierarchy Custom Settings
A type of custom setting that uses a built-in hierarchical logic that lets you “personalize” settings for specific profiles or users. The hierarchy logic checks the organization, profile, and user settings for the current user and returns the most specific, or “lowest,” value. In the hierarchy, settings for an organization are overridden by profile settings, which, in turn, are overridden by user settings.

All custom settings data is exposed in the application cache, which enables efficient access without the cost of repeated queries to the database. However, querying custom settings data using Standard Object Query Language (SOQL) doesn't make use of the application cache and is similar to querying a custom object. To benefit from caching, use other methods for accessing custom settings data such as the Apex Custom Settings methods.

Hi Suraj

Salesforce does not provide any standard feature for history tracking on opportunity line items but by using custom object and trigger we can get to this solution

First you need to create custom object as i created opportunity_Tracking__c

trigger opportunitytracking on OpportunityLineItem(After insert, After update) {
List<opportunity_Tracking__c> hisTrackList = new List<opportunity_Tracking__c>();
//
// Iterate through the OpportunityLineItems and create the History Tracking Record.
//
for (Integer i=0; i < Trigger.new.size(); i++) {

OpportunityLineItems newCM = Trigger.new[i];
if(Trigger.isInsert) {
hisTrackList.add(new opportunity_Tracking__c(OpportunityLineItem_Record_Id__c = newCM.Id,
Object_Name__c = 'OpportunityLineItem',
Field_Name__c = 'Status',
Previous_Value__c = '',
Current_Value__c = newCM.Status,
Modified_Date_Time__c = System.now(),
Modified_By__c = UserInfo.getUserId()
));
} else if(Trigger.old[i].Status != newCM.Status){
OpportunityLineItem oldCM = Trigger.old[i];
hisTrackList.add(new opportunity_Tracking__c(OpportunityLineItem_Record_Id__c = newCM.Id,
Object_Name__c = 'OpportunityLineItem',
Field_Name__c = 'Status',
Previous_Value__c = oldCM.Status,
Current_Value__c = newCM.Status,
Modified_Date_Time__c = System.now(),
Modified_By__c = UserInfo.getUserId()
));
}
}
if(!hisTrackList.isEmpty()) {
insert hisTrackList;
}
}

Hi Manpreet

A standard field record name can have data type of either auto number or text field with a limit of 80 chars.

For generating auto numbers, the format needs to be specified while defining the field and after that for every record that is added, the number will get auto generated. For example:-
Sr No-{1}
Sr No-{2}
Sr No-{3}

Hope it may help:

Hi Manpreet

you can expose your Apex class and methods so that external applications can access your code and your application through the REST architecture. This is done by defining your Apex class with the @RestResource annotation to expose it as a REST resource. You can then use global classes and a WebService callback method.

Invoking a custom Apex REST Web service method always uses system context. Consequently, the current user’s credentials are not used, and any user who has access to these methods can use their full power, regardless of permissions, field-level security, or sharing rules.
Developers who expose methods using the Apex REST annotations should therefore take care that they are not inadvertently exposing any sensitive data

Look at the below piece of code for instance:-

global class AccountPlan {
webservice String area;
webservice String region;
//Define an object in apex that is exposed in apex web service
global class Plan {
webservice String name;
webservice Integer planNumber;
webservice Date planningPeriod;
webservice Id planId;
}
webservice static Plan createAccountPlan(Plan vPlan) {
//A plan maps to the Account object in salesforce.com.
//So need to map the Plan class object to Account standard object
Account acct = new Account();
acct.Name = vPlan.name;
acct.AccountNumber = String.valueOf(vPlan.planNumber);
insert acct;
vPlan.planId=acct.Id;
return vPlan;
} }

Hope it may help

Hi Suraj

It is always a best practice to write a single trigger on object and process all operation in apex class (we called it as handler) instead of writing logic in trigger. In handler you can specify the order of event based on different context variables. If you write many triggers in on object,
then you cannot control the order in which triggers gets executed.

For best practice, use below suggestion:

1. Pass all trigger context variables to static method (say "OperationManager")in handler class.
2. Create different static methods for different operations which you need to perform.
3. Control the order of different operation in "OperationManager" static method based on context variables.
4. Also you can create different apex classes and call them from "OperationManager" static method.

For example, below is modified code as per best practice.
Apex trigger code:

trigger JobTrigger on Job__c (after delete, after insert, after undelete, after update, before delete, before insert, before update)

{
String errMsg = JobTriggerHandler.OperationManager(trigger.new, trigger.old, trigger.newMap,trigger.oldMap,
trigger.isBefore,trigger.isAfter,trigger.isInsert,trigger.isUpdate,trigger.isDelete, trigger.isUndelete,trigger.isExecuting);

// If error occured, then display it to user
if (errMsg != null) {
if (trigger.isInsert || trigger.isUpdate || trigger.isUndelete) { trigger.new[0].addError(errMsg); } else { trigger.old[0].addError(errMsg); }
}
}

Apex class(Handler):

public with sharing class JobTriggerHandler {
// Main entry point for this handler.
public static String OperationManager(list<Job__c> newList, list<Job__c> oldList, map<Id, Job__c> newMap,map<Id, Job__c> oldMap,
boolean isBefore,boolean isAfter, boolean isInsert, boolean isUpdate,boolean isDelete,boolean isUndelete, boolean isExecuting) {
String errMsg;
try {
// Only run a method if previous methods didn't fail
//As you want to perform operation on before insert and before update
if (isBefore && (isUpdate || isInsert) && errMsg == null) {
// Find hourly rate by calling static method defined below
errMsg = computeHourlyRate(newList);
}
//here you can call any other static methods or some other class method to perform desired operations
//keep on adding the other logic which needs to be processed through trigger
//through context variables you can control their execution
} catch (Exception ex) {
errMsg = ex.getMessage() + ' at ' + ex.getLineNumber().format();
}
return errMsg;
}

//Below method will compute hourly rate
public static String computeHourlyRate(list<Job__c> newList) {
String errMsg;
try {
Set<Id> AccID = new Set<Id>();
Set<String> JobType = new Set<String>();
Map<String,Rate_card__c> RateCardMap = new Map<String,Rate_card__c>();
for (Job__c Job: newList){
AccID.add(Job.Account__c);
JobType.add(Job.Type__c);
}
For(Rate_Card__c RateCard : [SELECT Id, Hourly_Rate__c, Account__c, Type__c FROM Rate_card__c WHERE Account__c IN: AccID]){
RateCardMap.put(RateCard.Account__c + RateCard.Type__c, RateCard);
}
For (Job__c Jobs: newList){
if(RateCardMap.containsKey(Jobs.Account__c+Jobs.Type__c)){
Jobs.Hourly_Rate__c = RateCardMap.get(Jobs.Account__c + Jobs.Type__c).Hourly_Rate__c;
}
}
} catch (Exception ex) { errMsg = ex.getMessage(); }
return errMsg;
}
}

Hi Suraj

Difference between Slds-has-flexi-truncate and Slds-truncate is given below:

         Slds-truncate

• Usage:  It can be applied to:-  Any element
• Outcome:Creates truncated text
• Required:No, optional element or modifier
• Comments:Truncation will occur at the parent width if a width is not specified

 Slds-has-flexi-truncate

• Usage:It can be applied to:.slds-col
  .slds-col--padded
• Outcome:Allows truncation in nested flexbox containers
• Required:No, optional element or modifier
• Comments:This class is placed on a parent element that contains a flexbox element containing .slds-truncate. For example — for a media object that is nested in a grid column and contains truncation — the grid column would require this class.

Hope it may help you:

Hi Suraj

In short, you can do everything you can do with workflows using process builder as well, except for sending outbound messages with point&click. With process builder, you can also update all child records starting from the parent record, which is not possible with workflows (only vice versa is possible using cross object field updates). I've heard rumors that process builder will replace workflows in the future, which seems a logical step to take for sfdc.

Hi Manpreet

All exceptions support built-in methods for returning the error message and exception type. In addition to the standard exception class, there are several different types of exceptions

Visualforce
If you have a custom controller or controller extension for a Visualforce page, you can handle exceptions just as in the examples above. To show the error on a Visualforce page, you can use the ApexPages.message class to create a message for display. Here's an example of a message created in a controller:

ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.FATAL,'my error msg');
ApexPages.addMessage(myMsg);

Sending an Email on exception
In addition to displaying the message to the user via page messages, you can also notify the developer by email if you like. Here's an example:

try{
update account;
} catch (DMLException e){
ApexPages.addMessages(e);

Messaging.SingleEmailMessage mail=new Messaging.SingleEmailMessage();
String[] toAddresses = new String[] {'[email protected]'};
mail.setToAddresses(toAddresses);
mail.setReplyTo('[email protected]');
mail.setSenderDisplayName('Apex error message');
mail.setSubject('Error from Org : ' + UserInfo.getOrganizationName());
mail.setPlainTextBody(e.getMessage());
Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
}

You could use this technique to ensure that error messages are sent to an error mailing list for example.

Logging in a custom object

If you get enough emails already, another option would be to use a future method to write a custom object that could catch the error details. Your try-catch would look something like this:

try{
throw new MyException('something bad happened!');
} catch (MyException e){
ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.FATAL,'my error msg');
futureCreateErrorLog.createErrorRecord(e.getMessage());
}

Your future class would look something like this.

global class futureCreateErrorLog {
@future
public static void createErrorRecord(string exceptionMessage){
myErrorObj__c newErrorRecord = new myErrorObj__c();
newErrorRecord.details__c = exceptionMessage;
Database.insert(newErrorRecord,false);
}
}

Hi Suraj

You can use the Database.executeBatch(sObject className, Integer scopeSize) method to set the new  batch size.

But you need to be sure that the scopeSize should less than 200.

Database.executeBatch(sObject className, 50 ) would set the batch size to 50 instead of 200

Hoping this may help you

[Saurabh]

Hi Suraj,

Yes You can use remote object. Visualforce Remote Objects are proxy objects that enable basic DML operations on sObjects directly from JavaScript. Remote Objects remove some of the complexity from JavaScript remoting by reducing the need for @RemoteAction methods in an Apex controller or extension.
