Salesforce Real Time Scenario: 3

 


Scenario: 3
Imagine you're working on a Salesforce project for a retail company. The company wants to automate the process of updating inventory levels in Salesforce whenever a new sales order is created. How would you approach this scenario using triggers?

    To address this scenario, I would first design a trigger that fires whenever a new sales order is created in Salesforce. This trigger would then update the corresponding inventory levels based on the products included in the sales order.

overview of the steps:

  1. Define Trigger Logic: Write an Apex trigger on the Sales Order object that executes after the record is inserted.


  2. Query Products: Query the related Product objects to determine the quantity of each product included in the sales order.


  3. Update Inventory Levels: Update the inventory levels for each product by subtracting the quantity sold from the available inventory quantity.


  4. Handle Error Conditions: Include error handling logic to check for scenarios where the quantity sold exceeds the available inventory, and handle these cases appropriately (e.g., raising an exception or sending an alert).

Here trigger code:

trigger UpdateInventory on Sales_Order__c (after insert) { List<Product__c> productsToUpdate = new List<Product__c>(); for(Sales_Order__c order : Trigger.new) { for(Sales_Order_Line_Item__c lineItem : order.Line_Items__r) { // Query product and update inventory Product__c product = [SELECT Id, Quantity_On_Hand__c FROM Product__c WHERE Id = :lineItem.Product__c]; product.Quantity_On_Hand__c -= lineItem.Quantity__c; productsToUpdate.add(product); } } // Update inventory levels if(!productsToUpdate.isEmpty()) { update productsToUpdate; } }

    This trigger fires after a new sales order is inserted and updates the inventory levels for each product included in the order. It queries the related products, subtracts the quantity sold from the available inventory quantity, and updates the Product records accordingly.

    Additionally, we would need to consider bulkification, error handling, and testing to ensure the trigger performs efficiently and reliably in a production environment.
