5 Steps To Easily Add A Salesforce Field

Customizing your Salesforce org to meet your specific business needs is essential for maximizing its functionality. One of the core aspects of customization is managing your data, and a crucial part of that is adding new fields to capture the information you require. Adding fields to your Salesforce org is a relatively straightforward process, but it’s important to understand the implications and best practices involved to ensure a successful implementation.

Before embarking on the process of adding a new field, it’s essential to carefully consider your requirements. Determine the type of data you need to capture, the format it should be stored in, and the accessibility and visibility requirements. Additionally, consider the impact on existing workflows, reports, and integrations. A well-thought-out plan will help prevent costly rework later on.

Once you have a clear understanding of your needs, you can proceed to add the field to your Salesforce org. Salesforce provides a user-friendly interface that guides you through the process, allowing you to specify the field’s properties such as its name, data type, length, and default value. Additionally, you can configure field-level security to control who has access to the data and how they can interact with it. By following these steps and best practices, you can effectively add a Salesforce field and enhance the functionality of your org to meet your evolving business needs.

Understanding Custom Metadata Types

Custom Metadata Types (CMTs) are a Salesforce feature that allows you to create and store custom data types that can be used by other objects and components. CMTs are similar to custom objects, but they have some key differences:

CMTs are stored as metadata, which means they are not subject to the same storage limits as custom objects.
CMTs can be used by any object or component that has access to the metadata API, including Apex and Visualforce.
CMTs are not available in the Salesforce user interface, so they must be managed through the metadata API or the Developer Console.

CMTs can be used to store a variety of data, including:

Data Type	Description
Text	A single line of text, up to 255 characters
Long Text	A multi-line text, up to 32,000 characters
Number	A numeric value
Boolean	A true or false value
Date	A date value
Picklist	A list of pre-defined values
Hierarchical	A tree-like structure of values

Creating a Custom Metadata Record

A Custom Metadata Record is a record that describes a custom field or object. It is used to define the properties of the field or object, such as its name, label, and data type. To create a Custom Metadata Record, follow these steps:

In Setup, click on “Object Manager”.
Click on the “Custom Metadata” tab.
Click on the “New Custom Metadata Record” button.
Enter a name for the Custom Metadata Record.
Select the type of Custom Metadata Record that you want to create.
Click on the “Save” button.

Once you have created a Custom Metadata Record, you can use it to define the properties of a custom field or object. To do this, click on the “Fields” or “Objects” tab in the Custom Metadata Record, and then enter the properties of the custom field or object.

The following table lists the different types of Custom Metadata Records that you can create:

Type	Description
Custom Field	A Custom Field is a field that you can add to an existing object.
Custom Object	A Custom Object is an object that you can create to store your own data.
Custom Setting	A Custom Setting is a collection of key-value pairs that you can use to store your own data.
Custom Label	A Custom Label is a label that you can use to translate your application into different languages.
Custom Profile	A Custom Profile is a profile that you can create to give users access to specific objects and fields.
Custom Permission	A Custom Permission is a permission that you can create to give users access to specific objects and fields.
Custom Report Type	A Custom Report Type is a report type that you can create to generate reports on your own data.
Custom Dashboard	A Custom Dashboard is a dashboard that you can create to display your own data.
Custom App	A Custom App is an app that you can create to extend the functionality of Salesforce.
Custom Network	A Custom Network is a network that you can create to connect your Salesforce org to other orgs.
Custom Integration	A Custom Integration is an integration that you can create to connect your Salesforce org to other systems.
Custom Metadata Type	A Custom Metadata Type is a type of Custom Metadata that you can create to define your own custom data.

Referencing the Custom Metadata Record

Locate the Custom Metadata Record that you want to associate with the field in Lightning Experience.

1. Navigate to the Setup menu and select Object Manager.
2. Select Custom Metadata Types.
3. Click the Custom Metadata Record you want to associate with the field.
4. Copy the unique ID of the Custom Metadata Record from the URL.

For example, if the URL is https://na1.salesforce.com/setup/ui/customMetadata/detail/03hB00000005ucDUAQ,
then the unique ID of the Custom Metadata Record is 03hB00000005ucDUAQ.

You can also reference the Custom Metadata Record by its API name. To find the API name, navigate to the
Custom Metadata Record and click View Details. The API name is displayed in the URL. For example,
if the URL is https://na1.salesforce.com/setup/ui/customMetadata/detail/03hB00000005ucDUAQ?view=detail,
then the API name of the Custom Metadata Record is CustomMetadataRecord.

For example, the following field definition references the Custom Metadata Record with the unique ID
03hB00000005ucDUAQ:

Field Name	Definition
`My_Custom_Field__c`	`CustomMetadataReference ( My_Custom_Metadata_Type__mdt , My_Custom_Value__c )`

Adding a Field to the Custom Metadata Type

To add a field to a custom metadata type:

In Setup, enter “Custom Metadata Types” in the Quick Find box, then select Custom Metadata Types.
Click the name of the custom metadata type you want to add a field to.
Click Fields, then New.
Alternatively, you can click Add Field directly from the Custom Metadata Type detail page.
For the Field Label, enter a human-readable name for the field.
For the API Name, enter a unique name for the field.
The API name can contain only underscores and alphanumeric characters, and must start with a letter. It must also be unique within the custom metadata type.
For the Field Type, select the type of data that the field will store.
Custom metadata fields can be of the following types: Text, Number, Date, Currency, Percent,Checkbox, Picklist, Multi-Select Picklist, Reference, and Master-Detail.
For the Length, enter the maximum length of the field if the field type is Text or Multi-Select Picklist.
For Text fields, the maximum length is 255 characters. For Multi-Select Picklist fields, the maximum length is 255 values.
For the Default Value, enter the default value for the field.
The default value is the value that will be assigned to the field if no other value is specified when creating a new custom metadata record.
For the Description, enter a description of the field.
The description is optional, but it can be helpful for other users to understand what the field is used for.
Click Save.

Customizing the Field Properties

When customizing a field, you can specify various properties to control its behavior and appearance. These properties include:

Field Label

The field label is the text that appears next to the field on the user interface. It’s important to choose a clear and concise label that accurately reflects the purpose of the field.

Field Type

Salesforce offers a variety of field types to meet different data storage requirements. Common field types include text, number, date, and picklist. Choose the field type that best suits the type of data you want to store.

Field Length

For text and number fields, you can specify the maximum length of the data that can be entered. This helps ensure data integrity and prevents users from entering data that exceeds the field’s capacity.

Decimal Places

For number fields, you can specify the number of decimal places to display. This allows you to control the precision of the data stored in the field.

Default Value

You can set a default value for a field, which will automatically populate the field when a new record is created. This can save time and reduce the risk of errors by ensuring that certain fields always have a valid value.

Validation Rules

Validation rules allow you to define criteria that must be met when data is entered into a field. If a validation rule is violated, an error message will be displayed and the user will be prevented from saving the record. Validation rules help ensure data quality and business rules are enforced.

Displaying the Field in Salesforce

Once you have created a custom field, you need to make it visible in Salesforce so that users can access and interact with it. Here’s how to display a custom field in Salesforce:

1. Page Layouts

Page layouts enable you to customize the layout of Salesforce record pages, including which fields are displayed. To add a custom field to a page layout:

Navigate to the Setup menu.
Go to “Object Manager”, select the object type, and click on “Page Layouts”.
Edit the desired page layout.
Drag and drop the custom field from the “Fields” section to the desired location on the page layout.
Save the changes.

2. Field Sets

Field sets are containers that group related fields together. To add a custom field to a field set:

Go to “Setup” and select “Objects”.
Choose the object type and click on “Field Sets”.
Edit the desired field set.
Drag and drop the custom field into the field set.
Save the changes.

3. Lightning App Builder

In Lightning Experience, you can use the Lightning App Builder to customize the layout of Salesforce record pages and components. To add a custom field using the Lightning App Builder:

Open the Lightning App Builder.
Drag and drop the “Field” component onto the page.
Select the custom field you want to display from the dropdown list.
Configure the field’s properties, such as its label, visibility, and data type.
Save the changes.

4. Custom Visualforce Pages

Visualforce pages allow you to create custom pages within Salesforce. To add a custom field to a Visualforce page:

Create a new Visualforce page.
In the code editor, use the {!customFieldName} syntax to reference the custom field.
Deploy and activate the Visualforce page.

5. List Views

List views enable you to create filtered views of Salesforce records. To add a custom field to a list view:

Create or edit a list view.
In the “Available Fields” section, select the custom field.
Drag and drop the custom field to the “Selected Fields” section.
Save the changes.

6. Reports

Reports allow you to analyze and visualize Salesforce data. To add a custom field to a report:

Create or edit a report.
In the “Fields” panel, select the custom field.
Drag and drop the custom field to the report layout.
Configure the field’s aggregation or calculation, if necessary.
Run the report.

7. API and Apex

The Salesforce API and Apex code can be used to programmatically interact with custom fields. To access a custom field using the API:

Method	Description
getSObject()	Retrieves the value of a custom field from a Salesforce object.
setSObject()	Updates the value of a custom field on a Salesforce object.

To access a custom field using Apex, use the syntax: objectName.customFieldName.

Troubleshooting Common Issues

When adding a Salesforce field, you may encounter some common issues. Here are a few troubleshooting tips to help you address them:

1. Insufficient Permissions: Ensure that you have the necessary permissions to create or modify fields in the desired object. Check your user profile or contact your administrator for assistance.

2. Field Name Collision: Ensure that the field name you choose is unique within the object. Salesforce won’t allow duplicate field names.

3. Invalid Field Type: Choose the appropriate field type for your data. For example, a numeric field cannot store text values.

4. Field Label Limit: Field labels are limited to 255 characters. If you exceed this limit, Salesforce will truncate the label.

5. Required Field Dependence: If you create a field that is dependent on another required field, make sure the required field is populated with data before saving the record.

6. Picklist Value Limit: Picklist fields have a limit of 255 values. If you exceed this limit, you’ll need to use a different field type.

7. Validation Rule Conflicts: Check for any conflicting validation rules that may prevent the field from being saved.

8. Formula Field Syntax Errors: When creating formula fields, ensure that the syntax is correct and the referenced fields exist.

9. Code Coverage of Dependent Objects: If you create a field in a dependent object (e.g., a custom object that relates to a standard object), ensure that there is sufficient code coverage testing for the related object’s triggers and classes.

Error Message	Possible Cause	Solution
“Field Name is not unique”	Field name already exists	Choose a different field name
“Invalid Field Type”	Incompatible data type	Select the correct field type
“Field Required Error”	Required field not populated	Populate the required field

Best Practices for Custom Field Management

1. Plan and Document Your Fields

Before creating custom fields, thoroughly consider their purpose, audience, and usage scenarios. Document the field’s name, data type, accessibility, and any validation rules or dependencies.

2. Prioritize Fields by Importance

Identify the most critical fields for achieving your business goals. Prioritize them based on usage and impact, ensuring they are accessible and easy to use.

3. Use Standard Fields Whenever Possible

Before creating a custom field, explore using existing Salesforce standard fields or field types. This reduces redundancy and simplifies data management.

4. Name Fields Clearly and Concisely

Assign clear and unambiguous names to fields to avoid confusion and ensure consistent usage. Use descriptive but concise terms that accurately reflect the field’s purpose.

5. Consider Data Types Carefully

Select the appropriate data type for each field to ensure data accuracy and prevent errors. Consider the range, format, and validation requirements of the data.

6. Set Default Values and Validation Rules

Define default values to simplify data entry and ensure consistency. Establish validation rules to enforce data integrity and prevent errors during input.

7. Use Field-Level Security

Control access to fields based on user roles and permissions. This ensures data privacy and security by limiting exposure to sensitive or confidential information.

8. Review and Update Fields Regularly

Periodically evaluate the relevance and accuracy of your custom fields. Remove obsolete fields, update values, and adjust validation rules as needed to maintain data integrity.

9. Leverage Custom Field Types

Explore Salesforce’s custom field types to enhance data entry and storage. Use picklists, checkboxes, or multi-select options to streamline user input and provide structured data options.

10. Best Practice: Data Migration and Field Mapping

Scenario	Best Practice
Preparing for data migration	Identify and map custom fields between source and target systems to ensure data accuracy.
Merging or consolidating records	Map custom fields between records to preserve data integrity and avoid conflicts.
Updating bulk data	Use data loaders or APIs to efficiently update custom field values across multiple records.
