Automate Record Creation

Unit : Automate Record Creation

👉Install the unmanaged package for the schema and stubs for Apex classes and triggers. 

👉Rename cases and products to match the HowWeRoll schema, and assign all profiles to the custom HowWeRoll page layouts for those objects. 
👉Use the included package content to automatically create a Routine Maintenance request every time a maintenance request of type Repair or Routine Maintenance is updated to Closed.
👉Follow the specifications and naming conventions outlined in the business requirements.

#Apex Trigger

 trigger MaintenanceRequest on Case (after update) {  
   MaintenanceRequestHelper.updateWorkOrders();
