i didnt understand this scenario ,Can any one know how to create this by using flow and how to send chatter to this users SSAM Implementation Specialist or Account Manager ?

project is a Object & Create IP is field

Create a new chatter when: 
Create IP(field)  = 'True'
Chatter the SSAM Implementation Specialist or Account Manager
 @ Person
'The TIC has completed the creation of the IP Package for (Project Name)'

I'm parsing multiple invoices with N Products in each. I want to create Opportunities based on each invoice and each invoices product data. So I expect my Opportunities and OpportunityLineItems to be in relations like this:
- TestCorp (opportunity name):
- Products:
- Pen
- Book
- BioTech:
- Products:
- Laser
- Optical Fiber
- Beam Splitter etc...
But I'm getting
- TestCorp:
- Pen
- Pen
- BioTech:
- Book
- Book
- Book
Here is the logic to parse and store the data:

public with sharing class InvoiceParser {
    public static HttpResponse response = InvoiceCallout.makeGetCallout();
    public static JSONParser parser = JSON.createParser(response.getBody());
    public static Invoice invoiceJson = (Invoice)parser.readValueAs(Invoice.class);

        return pricebook2;
    }

    public static List<Opportunity> createOpportunity() {
        List<Opportunity> opportunities = new List<Opportunity>();
        System.debug('invoiceJson.files --- '  + invoiceJson.files);

Btw system.debug() says that Products and Opportunities creating correctly but it seems that I need to link them correctly but how? I've tried to create custom field on the Product to link with opportunity but it doesn't work anyway.

What's wrong here?

I have a class that selects target date and case id from an object CaseMilestone and then it puts it into a list and then it mappes the target date as the milestone date... I want to write a test class for it but my test class only covers 57% of the code... It is unable to enter the IF condition present in the main class

THE CODE FOR THE CLASS IS:
public class DisplayCaseMilestoneDateCtrl {
    @AuraEnabled(cacheable=true)
    public static string getCaseMilestoneDate(String caseId){
        List<CaseMilestone> cmList = [SELECT targetDate,caseId FROM CaseMilestone where caseId =: caseId];
        if(cmList != null && cmList.size() > 0){
            DateTime dt = cmList[0].targetDate;
            string milestoneDate = dt.format('d-MMM-yyyy hh:mm a');
            return milestoneDate;
        }
        else{
            return 'No milestone date to show.';
        }
    }
}

 

And THE CODE FOR THE TEST CLASS WITH 57% code coverage is:
@isTest
public class DisplayCaseMilestoneDateCtrlTest {
    static testmethod void testmethod1() {
        List<Id> idss = new List<Id>();
        CaseMilestone cms = new CaseMilestone();
        idss.add(cms.CaseId);
        Test.startTest();
        DisplayCaseMilestoneDateCtrl.getCaseMilestoneDate('500N000000J0MkfIAF');
        Test.stopTest();
        
    }
    
}

Hello All hope are doing good, I have several log files in a webDAV (salesforce SFDC logs repo) and I want to drop all of them to a linux server, so that I can feed them to Splunk Server Class. I am not sure if there is a better idea than this, please advise.

Thanks
Sarahjohn
