 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.

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.
