Step 1

• Make sure you create the Custom metadata records with the exact same names given (that matches the product families)
• In the constants apex class, declare all the properties as public static

Step 2

• OrderTrigger needs to handle only after update event
• OrderTrigger should use the Orderhelper internally for the rollup
• Don’t forget to remove the “with sharing” from the orderHelper class

Step 3

• Override the Add and New button under Product object to use the visualforce page
• Product2New visualforce page
  • in the pageblock table columns, use the field labels as headers using $ObjectType
  • update the column values to use the productRecord fields inside the productwrapper
  • use apex:chart to display the horizantal bar chart in a separate pageblock above the table
  • reRender the required components from the Save and Add buttons
• Product2Extension apex class
  • Make the Controller class “Without Sharing”
  • add the inner class ProductWrapper
  • replace the list of products with list of productwrapper
  • use Savepoint in the Save method
  • iterate thru the productWrapper and extract the products and pricebookentries and insert them separately
  • use try catch block and do a rollback if there are any errors
• ChartHelper apex class
  • Make the ContChartHelperroller class “Without Sharing“
  • move the chart data initialisation logic to Chart Helper class
  • make the GetInventory method @AuraEnabled

Step 4

This is probably the simplest of all the steps.. update theTestDataFactory class to handle the key requirements given..

• Make sure all the methods in the TestDataFactory class are Public Static and the class is marked “with sharing”
• all the construct methods should create the mentioned objects with the required fields and unique names and return the records without inserting them
• use the Insert method to call all the construct methods and then insert the records returned from those methods.

Step 5

• Update the VerifyQuantityOrdered method in TestDataFactory with a System.Assert to compare the Quantity Ordered between the Updated product and the original product plus the incoming quantity
• run both OrderTests and Product2Extension_UnitTest and make sure both the test classes are passing  and the classes they are intended to cover has more than 75% coverage

Step 6

• Don’t forget to create the chatter group “Inventory Announcements” .. mark it public and tick the disable auto archive checkbox and use the description text given
• update the product trigger to handle only after update and use the product helper class to handle the after update logic
• update the product helper class AfterUpdate method to use the postAlerts method which in turn will be using the AnnouncementQueueable class to process the chatter group notification
• AnnouncementQueueable is a Queueable class and uses ConnectApi to post the announcement

Step 7

• Override the New and Edit buttons under the Order object to use the OrderEdit visualforce page
