Introduction

This tutorial provides a step-by-step guide on key concepts covered in Day 5 of the Salesforce Bootcamp 2023, focusing on Lookup and Master-Detail fields, Rollup Summary fields, and Junction Objects. This guide is designed for anyone looking to enhance their skills in Salesforce, whether you're a beginner or looking to solidify your understanding of these critical components.

Step 1: Understanding Lookup Fields

Lookup fields create a relationship between two objects in Salesforce. Here’s how to set one up:

1. Navigate to Object Manager:

   • Go to Setup and click on "Object Manager".

2. Select the Object:

   • Choose the object you want to add a Lookup field to (e.g., Account or Contact).

3. Create a New Field:

   • Click on "Fields & Relationships".
   • Select "New" and choose "Lookup Relationship".

4. Choose the Related Object:

   • Select the object you want to relate to (e.g., Contact if you are on the Account object).

5. Configure Field Settings:

   • Provide a field label and name.
   • Set any additional options such as making the field required.

6. Add to Page Layout:

   • Ensure the field is added to the appropriate page layouts for visibility.

Step 2: Master-Detail Relationships

Master-Detail relationships provide a stronger link between two objects, with specific behaviors such as cascading delete.

1. Access Object Manager:

   • As in Step 1, go to "Object Manager".

2. Select the Object:

   • Choose the primary object (Master) for the relationship.

3. Create a New Field:

   • Navigate to "Fields & Relationships".
   • Select "New" and choose "Master-Detail Relationship".

4. Choose the Detail Object:

   • Select the object that will be the detail (dependent) in the relationship.

5. Configure Field Settings:

   • Provide a name and label for the field.
   • Decide on options such as sharing settings and whether the related record can be deleted.

6. Add to Page Layout:

   • Ensure that the Master-Detail field is included in the relevant page layouts.

Step 3: Creating Rollup Summary Fields

Rollup Summary fields allow you to perform calculations on related detail records.

1. Select the Master Object:

   • Go to the object that has the Master-Detail relationship.

2. Create a New Field:

   • In "Fields & Relationships", click "New" and select "Roll-Up Summary".

3. Configure Roll-Up Summary:

   • Select the detail object.
   • Choose the roll-up operation (SUM, MIN, MAX, COUNT).
   • Specify the field to summarize.

4. Set Field Properties:

   • Name the field and configure field-level security.

5. Add to Page Layout:

   • Include the Rollup Summary field in the appropriate page layouts.

Step 4: Understanding Junction Objects

Junction Objects are used to create many-to-many relationships between two objects.

1. Create a New Custom Object:

   • Go to "Object Manager" and click "Create" to make a new custom object (e.g., Course Enrollment).

2. Add Master-Detail Relationships:

   • Create two Master-Detail relationships within the Junction Object:
     • One for the first object (e.g., Student).
     • One for the second object (e.g., Course).

3. Configure the Relationships:

   • Ensure that both relationships are set properly, allowing for the many-to-many relationship.

4. Add to Page Layout:

   • Include fields from both related objects in the Junction Object’s page layout for easy data entry.
