Example of hierarchy custom settings

Let's consider an example where you want to set different approval limits for different user profiles using Hierarchy Custom Settings.

Create Hierarchy Custom Setting

  • Navigate to Setup > Custom Settings.
  • Click "New Custom Setting" and create a new setting named "Approval_Limits__c" with a field named "Approval_Limit__c" (a numeric field representing the approval limit).

Add Default Value

  • In the "Manage" section of the custom setting, add a default value for the approval limit, let's say $10,000

Create Records for Specific Profiles

Create records for specific profiles with different approval limits. For example:

  • Profile: Standard User, Approval Limit: $5,000
  • Profile: Contract Manager, Approval Limit: $20,000
  • Profile: Administrator, Approval Limit: Unlimited

Access Hierarchy Custom Setting in Apex

In your Apex code, you can access the approval limit based on the user's profile.

Decimal userApprovalLimit = Approval_Limits__c.getInstance().Approval_Limit__c;

This code will dynamically retrieve the correct approval limit based on the user's profile in the hierarchy.

Use Approval Limit in Logic

Use the retrieved approval limit in your business logic. For example:

Decimal purchaseAmount = calculatePurchaseAmount();  // Some business logic to calculate the purchase amount.
if (purchaseAmount <= userApprovalLimit) {
    // Process the purchase approval logic.
} else {
    // Display an error or take appropriate action for exceeding the approval limit.
}

This way, the approval limit is customized based on the user's profile, allowing for different approval thresholds for different profiles.

In this example, the hierarchy custom setting enables you to set default values and then override those values for specific profiles, providing a flexible way to manage approval limits across different user profiles in Salesforce.

Testing of Approval Limits

The FSRK_ApprovalLimitsTest class contains test methods to verify the correct setting of approval limits for different user profiles. Each method tests a specific use case, ensuring comprehensive coverage of the functionality.

    public final static String STANDARD_USER = 'Standard User';

     */
    public static void insertCustomSetting(User user, Decimal approvalLimit) {
        FSRK_ApprovalLimits__c setting = new FSRK_ApprovalLimits__c();
