Process Builder Overview:

Process Builder is a graphical representation of your process as you build it. It consists of

Criteria, Immediate and Scheduled Actions.

There are following things which can be done by process builder:

  • Create Records:In addition to updating a record, you can create a record and set the field values within the record.
  • Create Chatter Post:   Push a chatter update into Group or Feed.
  • Create an approval:Traditionally you needed a trigger to push a record into an approval process automatically. With Process builder, you can do this automatically based on criteria of the process.
  • Quickly consolidate Workflow:Quickly consolidate multiple workflow rules that in one process.
  • Call an Apex Class:You can now call an Apex class.

Trigger Overview:

A trigger is the piece of code, that is executed Before or After a record is inserted or updated.

Usually, an APEX (code) based evaluation of criteria to set off a chain of events.These events execute the following types of operations

  • Insert
  • Update
  • Delete
  • Merge
  • Upsert
  • Undelete

 

In Apex Trigger you must have :
  • Need to programming knowledge.
  • Need to design test classes to meet required test coverage.

But the main difference in process builder is you can not delete any record and can’t show any error. For these, you have to write Trigger code. For example:

Apex Limitations
  • Total number of records retrieved via SOQL queries                                       50,000
  • Total number of records retrieved by DML                                                        10,000
  • Total number of SOSL queries issued                                                                 100(Sync) | 200(Async)
  • Total number of SOSL queries issued                                                                 20
  • Total number of records retrieved by a single SOSL query                             2,000
  • Total number of DML statements issued                                                           150
  • Maximum number of characters for a trigger                                                   1 million

 

Process Builder Limitations:

Editing:User can’t edit process once it has been activated.Therefore much like with flow, a new process needs to be created by cloning the initial process and making modifications to that cloned records.

Validation:Processes DO NOT  trigger Validation rule and can, therefore, invalidate data.

Deletion:The inactive process can’t be deleted for at least 12 hours after inactivation and do not appear in the Recycle Bin

Error Message:You can’t specify error messages when creating a process that doesn’t trigger as you can with flow or validation rules.

Formula help:When utilizing formula in criteria, there is no function help preview next to the syntax

Syntax: Pick-list fields are evaluated as text fields in process builder so that they won’t support any pick list formulas like ISCHANGED or ISNEW.

Apex Trigger  best practices:

  • Apex code must provide exception handling.
  • When query large data set use an SOQL FOR loop
  • Don’t use  SOSL and SOQL inside for loop.
  • Avoid Hard Coding IDs
Process Builder best practices:
  • Check: To see if there are any workflows on the object doing the same things as the process. Also, verify no active Apex Trigger
  • Avoid: Interviewing Apex, workflows, and processes together for the same process
  • Document: Use the Description field to populate information such as when it was created by who and what the process does.Also, if processes work in conjunction with each other.
  • Test: And then test some more.Especially when you are first starting to use this please practice in the sandbox first.

 

There’s a lot of ability to impact users and data here if you do something wrong.

  • Now the question is Why Process Builder and how is it differ from trigger?

Process builder is fully customization. No code required here because we require lengthy logic and record to complete and fulfill the requirement or if we using process builder it will take less time to complete the requirement.

It has some benefits over the trigger:

 

SCENARIOS OPTION REASON
Scenario I

Populate a lookup field on record update:

Traditionally required a trigger and It can be done easily with process builder.

The issue is Multi layer lookup logic- i.e. multiple / nested maps of related data required in the trigger.

          Process builder Trigger Traditionally been something that requires a Trigger. Process builder allows administrator can do this without the use of the code.
Scenario II

Set an Account Owner based on Record criteria

Process builderTrigger Process builder can be used to assign ownership of records based on criteria in the object.
Scenario III

Post a chatter message based on record criteria

Process builderTrigger Process builder can be used to post to chatter based on record criteria.
Scenario IV

Submit a Quote for Approval when Opportunity Stage= Proposal

Process builder Trigger Requires 2 Processes one to Update the Quote based on the opportunity stage and another to submit the quote for the approval when the criteria on the quote had been met.
Scenario V

Launch a Flow via record criteria vs a button or link.

Process builderTrigger Process builder can be used to set record criteria and then launch a trigger ready flow.
Scenario VI

Clone an opportunity and change the field values

Process builderTrigger Although Process builder can create a new record it can’t reference any of the values from the cloned opportunity without the use of a flow to capture the opportunity values.

Let’s have a look on given Process builder example :

Allow Contact to copy Current User Address in Contact Address and Account Billing Address only when any address field(Street, Country, state )is blank/NULL.

Step 1:

Make your Process-builder on Contact Object. Provide the criteria as Contact.Mailing Street (IS NULL = FALSE) and likewise for every address fields of Contact and Opportunity.

Step 2:

In “Immediate Action” give reference of Mailing Country to that of Contact.Owner.Country and Activate your Process as:

 

 

Step 3:

 

Now test this process builder in your org by leaving any address field blank in your org.

 

 

 

Step 4:

After leaving Contact address blank here is the address which got autofilled same as contact’s owner address. Similarly you can test this for your Contact’s Account.

 

 

 

This is the reason for using Process builder rather than using Apex.

But  in some scenarios you’ll have to write trigger code where process builder can’t be.
For example:

Create a checkbox field “SAME COUNTRY AS USER & COMPANY”. Throw error when a Contact is getting inserted in Salesforce having Country same as User country and Company country.

Above example can’t be done via Process builder since this do not allow you to throw error while inserting Contact.
Create  Checkbox field named “SAME COUNTRY AS USER & COMPANY” on Contact.

 

APEX CLASS:

public class SameUserAndCompanyCountryContact {

public static void sameCountry(List<Contact> conList){

   User user = new User();

   user = [SELECT Id , Country , CompanyName from User where Id =:

   UserInfo.getUserId()];

   System.debug(‘>>>>>>>>>>RB<<<<<<<<<<<<‘+user);

Organization orgDetails = [ SELECT Name , Country , Address from Organization where Name =: user.CompanyName];

System.debug(‘>>>>>>>>>>>RB<<<<<<<<<<<<‘+orgDetails);

for(Contact con : conList) {

 if(con.MailingCountry == user.Country && con.MailingCountry == orgDetails.Country){

    con.addError(‘Country of Company and User is same as country of Contact trying to   

         insert’);

    con.Same_Country_As_User_And_Company__c = True;

        }

     }

  }

}

APEX TRIGGER:

trigger ErrorOnSameCountry on Contact (before insert) {

 List<Contact> conList = Trigger.new;

    if(conList!=null) {

      SameUserAndCompanyCountryContact.sameCountry(conList);   

   }

}
Although the usage of process builder over apex trigger or vice versa is dependent on various other factors too, such as:

  • Complexity Of Codes.
  • Programmatic Logics.
  • Rapid Iteration In Process Builder Can Be Challenging.
  • Unit Test Considerations.
