How to assign Leads in a Round Robin fashion?

May 16, 2013 § Leave a comment

Round Robin Lead Assignment Process summary
This process mainly revolves around a set of users for a particular role (if the round robin needs to be assigned within the users of that role) or can also be completely different set of users from different role hierarchies. The users are set in the Lead Assignment rule using each criterion. Following are some high level requirements before making the round robin functional:
– Create a number field; let’s say “Lead Auto Increment ” and this field is being incremented using a trigger.

– Another formula field is created after this, let’s say “Small Market Assignment” (assuming users are from a role named “Small Market”) which will be as follows:
IF( NumberOfEmployees < 5001, MOD(Lead_Auto_Increment__c, 4), 99999)

– The Small Market Assignment will be populated based on the value of Lead Auto Increment. The MOD function is going to take our Lead Auto Increment value, do a bit of math and return a number in a range we specify. The “4” in the formula above means that it will return a number of 0, 1, 2, or 3. For the sake of our example here, we’re going to assume that we need to implement round robin assignment between 4 users and so the 4 in the formula. Depending on the number of users for our round robin, this value can be changed anytime. The formula is taking our Lead Auto Increment field and creating a Small Market Assignment value.

– Here in the formula, we are taking into consideration a business need for the round robin assignment. Any lead which has “No. Of Employees” less than 5001 will be considered as a criterion to be under the round robin assignment.

– Now, we have the two fields and the trigger in place. But there is a catch here. As we have decided to keep incrementing the Lead Auto Increment value and it is a field under the Lead object, we cannot keep track of the last value of this field in the last lead record created.

– For this, we will need some way to store the latest value of Lead Auto Increment field. Here, custom setting feature of Salesforce comes for our rescue. We will need to create a custom setting and create a field there; let’s say “AutoIncrement” which will store the latest value of the field “Lead Auto Increment”.
For example, we created a new Lead and the trigger updated the value of Lead Auto Increment to 0 since it has number of employees less than 5001 (we can add more conditions in the trigger based on the business requirement). Now, the custom setting field AutoIncrement will store the value 1. Next time, another lead is created/inserted, the Lead Auto Increment value will be 1 and AutoIncrement will be set to 2. This is accomplished using the same trigger.

Assignment Rules

– Further, if we think proactively, we will also realize that if an existing lead which is already assigned to one of those users (taken into consideration of our round robin assignment rule) is edited and meets our criteria again, then the trigger will update the Lead Auto Increment value and hence the Small Market Assignment value will be updated and finally, the lead will be re-assigned to another user. We don’t want this to happen.

– So, here we can create another field in the same custom setting; let’s say “Users” and store the Salesforce usernames of those users considered to be within our round robin rule. So, the trigger will check the criteria and before it updates the Lead Auto Increment value it will check if the current lead record owner is among these usernames stored in this field “Users”. If it is then the Lead Auto Increment value will not be updated and consequently, the Small Market Assignment value will not populate as well as the Lead Assignment rule will not trigger.

Custom Settings

– Also, please make a note that we need to start the value of the custom setting field “AutoIncrement” to 0(zero) in the very beginning. Also, sometimes Admins can forget to set this initial value, it is always a good practice to set this value from the trigger itself initially and keep on updating with the latest value going forward with each lead creation.

Running a Batch Job in Apex with mass records

March 5, 2012 § Leave a comment

A scenario comes when you need to process mass records either updating or inserting or deleting. We can make use of Batch Apex to process all the records at once.

Excerpts from the Force.com Winter ’10 Release :
Batch Apex gives you the ability to operate over large amounts of data by chunking the job into smaller parts, thereby keeping within the governor limits. Using batch Apex, you can build complex, long-running processes on the Force.com platform. For example, you could build an archiving solution that runs on a nightly basis, looking for records past a certain date and adding them to an archive. Or you could build a data cleansing operation that goes through all Accounts and Opportunities on a nightly basis and reassigns them if necessary, based on custom criteria.

In order to develop our Batch Apex, we need to create a new Apex class which extends “Database.Batchable” interface.

This interface will have three methods to be implemented:

  • start
  • execute
  • finish

“start” method is called at the beginning of a batch Apex job. Use this method to collect the records (of objects) to be passed to the “execute” method for processing. The Apex engine, automatically breaks the massive numbers of records you selected into smaller batches and repeatedly calls the “execute” method until all records are processed.

The “finish” method is called once all the batches are processed. You can use this method to carry out any post-processing operation such as sending out an email confirmation on the status of the batch operation.

Let’s take a closer look at each of these methods:
1. Start Method

global Database.QueryLocator start(Database.BatchableContext BC) {
      //passing the query string to the Database object.      
      return Database.getQueryLocator(query);
}

2. Execute method

 global void execute(Database.BatchableContext BC, List<sObject> scope){
    List<Account> accns = new List<Account>();

   for(sObject s : scope){Account a = (Account)s;
        if(a.OwnerId==fromUserId){
            a.OwnerId=toUserId;
            accns.add(a);
            }
        }
update accns;
}

3. Finish Method

global void finish(Database.BatchableContext BC){
  // Get the ID of the AsyncApexJob representing this batch job  
  // from Database.BatchableContext.    
  // Query the AsyncApexJob object to retrieve the current job's information.  

 AsyncApexJob a = [Select Id, Status, NumberOfErrors, JobItemsProcessed,
   TotalJobItems, CreatedBy.Email
   from AsyncApexJob where Id =:BC.getJobId()];

  // Send an email to the Apex job's submitter notifying of job completion.  
  Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
  String[] toAddresses = new String[] {a.CreatedBy.Email};
  mail.setToAddresses(toAddresses);
  mail.setSubject('Apex Sharing Recalculation ' + a.Status);
  mail.setPlainTextBody('The batch Apex job processed ' + a.TotalJobItems +
    ' batches with '+ a.NumberOfErrors + ' failures.');

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

Passing the Force.com certified Developer Exam (401)

December 7, 2011 § Leave a comment

This is just a small post I thought would be relevant to let you guys know that I have passed the salesforce.com certified Developer exam i.e the 401 exam and how to go about it with some insights from my own experience. The exam I would say won’t be that tough for someone who have worked for sometime and have got some hands on experience on the platform. Most of the questions are from the Administrative perspective i.e the 201 exam I should say. The rest are some advanced things one should know about the other features of the Force.com platform.

There are a lot of questions on sharing and security settings and some of them are scenario-based. For Example:

Q. A record was created and the option to share the record through Hierarchies has been unchecked. Who all can make changes to the record?
a. only the Owner
b. the owner, the members above the owner in the hierarchy and the administrator
c. the owner and the system administrator
d. only the system administrator.

Another Example:

Q. Features of force.com platform that are enabled by default when we create a custom tab for an object.
a. Create new on the sidebar.
b. Search on the sidebar
c. Quick create on the sidebar
d. Recent Items on the sidebar

Then expect some direct questions like :

Q. What is the size of a visualforce page? 15 MB

Last but not the least, there will be some questions on which tool you will use with a given business requirement.

These are pretty much one should know before heading for the 401 exam. Many of the things will be what you would have come across in the force.com platform itself and if you need any further help or have some queries, feel free to ask me or just mail me. I would be glad to help you out.

Using the Data Loader for Migration of Objects (Master-Detail relationship)

November 3, 2011 § Leave a comment

Using a Data Loader to migrate data from one Org to another is not that quite simple when there is a Master-detail relationship to be taken care of and maintaining the same relationship in the destination Org. I could not for the life of me remember the steps to follow whenever I am required to use Data Loader is such scenarios. And so I happen to write it down somewhere in a scrap paper and now as I have a running blog to share, I can post this and get a look every time I am going to use it in future and hopefully many will find it useful coming across this post.

Pre-requirement before following the below steps:

  1. You should have one csv file exported from the source Org which has all field values of the Master Object to be migrated to the destination Org.
  2. You should have a second csv file exported from the source Org which has all field values of the Detail Object along with the lookup ID field to the Master Object.

So here are the steps:

  • Create an External ID field in the Master Object of destination Org
  • Import the Master Object into destination Org with the ID field values(Source Org) inserted into the External ID field of destination org.
  • Export the Master Object from the destination Org along with the new ID field and the External ID field values as a CSV file.
  • Convert the ID values of both the master Object (in the csv file exported from Destination Org) and the detail Object (already exported from the source org) into a string of length 15 and then convert them with Tim’s formula to get the last 6 values of the each string in digits.
    • converting into string of 15 : =LEFT(A2,15)
    • Tim’s Formula : A3&CODE(MID(A3,13,1))&CODE(MID(A3,14,1))&CODE(MID(A3,15,1))
  • Convert any DATE fields with this formula before inserting into the destination Org
    • TEXT(A2,”yyyy-mm-ddThh:mm:ss”)&”.000Z” or select the date column and select ‘format’->’custom’ and type = yyyy-mm-ddThh:MM:ss:sssZ and press OK
  • Use VLOOKUP on the detail Object CSV file to match with the values in the Master Object CSV file
    • vlookup formula : VLOOKUP(value, table_array, match_value, case_sensitive or not(Boolean))
    • where value is the column in detail Object csv file to be searched or matched in Master Object csv file
    • and table_array is the fields(e.g. A1 to D1 till the last row) to be selected for matching in the Master Object csv file
    • and match_value is the no of the column next(usually 2) to the matched column(usually 1) in the Master Object csv file.
    • case_sensitive is the value to be given in VLOOKUP as a Boolean value either TRUE or FALSE to match for case-sensitivity.

In order to give these steps a graphical view, I have also created a diagram that can well explain what I am trying to convey in a simple way.

Data_Loader_flowOfSteps

A simple graphical view of steps to use Data Loader

In the diagram above, I have taken a simple example of an Account (Master Object) and Contact Object (Detail Object).

Feel free to comment and make this post more useful. I might not be clear in some of the steps above and it can be simplified more for beginners to understand.

Using the Inbound Email Service of Salesforce.com

November 2, 2011 § Leave a comment

If anybody has not come across this feature of Salesforce, then feel free to grok here as it is an out of the box functionality. This can help someone who needs to receive an email from outside of Salesforce and do something within Salesforce using an Apex class.

Just go to: Setup -> Develop -> Email Services.

Rest of the things are pretty straight forward. Click on “New Email Service” to create one. And then you can look up on Defining Email Services to fill in the details without much of an issue.

You would require an Apex Class to select for the field labeled as “Apex Class”. So, lets look at what you can do here:

global class ProcessEmail implements Messaging.InboundEmailHandler {
 
  global Messaging.InboundEmailResult handleInboundEmail(Messaging.InboundEmail email, Messaging.InboundEnvelope envelope) 
  {
 
    Messaging.InboundEmailResult result = new Messaging.InboundEmailresult();
 
    String str = email.plainTextbody;
    List parts = str.split('\n');
    String obj_name = parts[0];
    Id obj_Id = null;
    try{
        obj_Id = [Select id from Object__c where Name =: obj_name].Id;
        
        Attachment attachment = new Attachment();
        attachment.ParentId = obj_Id;
        attachment.Name = email.subject;
        attachment.Body = Blob.valueOf(email.htmlbody);
        attachment.ContentType = 'html';
        insert attachment;
    }catch(Exception qe){
  
        Messaging.reserveSingleEmailCapacity(2);
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();

        String[] toAddresses = new String[1];
        toAddresses[0] = email.fromAddress;
        
        System.debug('====&gt; to addresse '+toAddresses[0]); 

        mail.setToAddresses(toAddresses);
        mail.setReplyTo('mandeep.deka@mycompany.com');
        mail.setSenderDisplayName('App Support Administrator');
        mail.setSubject('App Support');
        mail.setBccSender(false);
        mail.setUseSignature(false);
        mail.setPlainTextBody('The Object: ' + obj_name  +' did not match with our app.');
        mail.setHtmlBody('Your Request to add your email as an attachment to the Object_Name:<b> ' + obj_name +' </b>has not been created.'+
             'A matching record could not be found in the app');

        Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
    }
       
    // Return the result for the Force.com Email Service
    return result;
 }
}

Here in the above class what we are doing is that we are reading the email sent from an anonymous address and trying to match the first line of the email with one of our Object record Name in Salesforce.com and based on that we attach the email body as an attachment to the respective Object record.

We also used a try and catch block to see if the Object record name matches with our record in Salesforce.com and if it doesn’t then we shoot back an email to the anonymous user based on the email address used to send the email to Salesforce.com.

Next, what we need to do is just add an Email address to publicize to those potential users who are going to send email to Salesforce.com i.e. to our app here.

If you have closed the Email Service window, better to open it and when you scroll down you will see a button to add “New Email Address”. Click on it and fill in the form using the help from this link Defining Email Service Addresses.

You just need to fill in the local part of the email address. Salesforce generates a unique domain-part for each email service address to ensure that no two email service addresses are identical. The generated domain-part appears to the right of the Email Address field.

One last thing that I would like to add here is that there might be a scenario when you might want to use the Email templates in Salesforce.com to use while reverting back to the anonymous user. In that case, take a look into this post Salesforce: Using basic email templates from Apex code.

One drawback of using Email Template is that the user sending the email cannot be anonymous anymore as he/she will have to be from either the Account, Contact or User because Email templates uses merge fields and there has be some access rights linked to the user who can view these fields if there are restricted sharing settings.

A few other links that might be helpful in using these service:
