How to Create Roll-Up Summary Field in Salesforce

In the Salesforce tutorial, I will explain how to create a roll-up summary field in Salesforce lightning and Salesforce classic step by step.

A roll-up summary field can be used to summarize the data of all the child records and display the information on the master record.

Let’s take an example to imagine there are two objects. Object A and the Object B and these two objects are related to each other in which A is on one side of the relationship and B is on the many sides of the relationship.

The multiple B records are associated with single A records. In that case, we summarize the field value on all the child records and display that field value on the master record in that situation we create a roll-up summary field.

What is a roll-up summary field in Salesforce?

The roll-up summary automatically shows the output on the master records while summing up data from a set of related detail records.
