Formula Field In Salesforce

 Formula fields are custom READ-ONLY fields that derive their value from a formula expression you define. It calculates the latest value when it is viewed or when any of the source fields changes. We can use formula fields in Reports and SOQL queries.

Below are some characteristics of the Formula field in Salesforce:

  • Formula fields are READ-ONLY fields. We can not change/update their values at own.
  • Formula fields derive/calculate the values using the Formula expression.
  • When the source field changes, the value of the formula field is automatically updated.
Formula field return type: We can create formula fields of only below mentioned returned type:
  • Checkbox
  • Currency
  • Date
  • Date/Time
  • Number
  • Percent
  • Text
  • Time
Note: We can use one formula field in calculation other formula fields.

Limit: The formula field can contain up to 3900 characters(including spaces, and comments). If we need more characters then we can divide the formula in different parts and can create separate formula field for each formula and then reference these formula fields in main formula field.

Difference between var, let and const keyword in JavaScript

 In JavaScript, We can declare a variable using below keywords: var let const Below are the difference between these keywords: Scope: The scope of the "var" keyword is the global scope. Means variables defined outside the function can be accessed globally. <script>     var a = 20;     function fun() {         if (true) {              var b = 30 // declared in "if" block but can be accessible outside of this "if" block.         }         console.log(b);         console.log(a);     }     fun(); </script> Output:  30 20 The scope of a "let" variable is only block scoped. It can’t be accessible outside the particular block. Have a look at below example: <script>     let a = 20;     function fun() {           if (true) {          ...

Salesforce Record Id

 Record Id is used to identify the record uniquely in a Salesforce Org. There are 2 types of record Id in Salesforce: 15 digit 18 digit 15-digit record Id is case-sensitive where as 18-digit record Id is case-insensitive .  15-digit record Id is referenced in UI and also visible in browser. It is true in classic but in lightning 18 digit record Id is being used in UI and also visible in browser. 18-digit record Id is referenced through the API. The last 3 digit of the 18-digit record Id is a check sum of the capitalization of the first 15 characters. A 15-digit record Id can be converted into 18-digit record Id using CASESAFEID() function. To convert 18-digit record Id into 15-digit record Id, simply remove last 3 digits from 18-digit record Id. Why we need 18-digit record Id when there was 15-digit record Id: Apex is a case-insensitive language. As 15 digit record Id is case-sensitive therefore we can not use it directly in Apex code. Therefore earlier in classic we were con...

Salesforce External ID

 An External Id is a custom field that has "External Id" attribute checked. Its used to contain unique record identifiers from a system outside of Salesforce. Salesforce allows us to mark only custom field with data type Text , Number or Email as External Id. Note: External Id is not case-sensitive.  Considerations: External Id is an attribute that can be added to a custom field to indicate that it should be indexed and treated as an Id. Its a user-defined cross-referenced field. It can be created for custom field type(Text, Number and Email only). Each object can have up to 25 External Ids. Benefits:  It helps improve report and API SOQL performance.  It can be used with UPSERT DML operation to seamlessly integrate apps with other system. No need to know Salesforce Record Id to load data. Very convenient for data integrations and migrations. The import wizard will detect existing records in Salesforce that have the same External Id. It becomes searchable in the s...
