Scenario Overview
In this scenario we are required to make a simple CSV list of all Product Line items associated with an Opportunitywhenever the Topic field is changed or whenever a Quick Button is clicked. We will save this list into the Description field for simplicity in this example.
North52 Decision Suite Solution
The North52 Decision Suite solution works like this,
- A formula of type 'Save - Perform Action' is created which triggers off both changes to a field Topic and clicking a Quick Button
- This formula creates a CSV list of all the Opportunity Products as a string variable
- The formula then saves this variable to the Opportunity entity's Description field
North52 Decision Suite Steps
Setup - Formula SetVarConcat
- Create a new formula of type Save - Perform Action
- Set the Event to 'Create and Update'
- Set Source Entity as 'Opportunity '
- Set Source Property as 'Topic'
- Click into the Formula Editor canvas
- Copy and paste the formula below into the Formula Editor
- Click Save
Now when you change the Topic in a Opportunity, the description will fill with a list of the Product Description (you may need to add a few  Product  Description  to see this ) 
Formula
SmartFlow(
  ForEachRecord(
    FindRecords('opportunityproduct',
                'opportunityid',
                [opportunity.opportunityid],
                SetFindSelect('productdescription') ,
                '50',
                'true'), 
    SetVarConcat('CSV List', 
                CurrentRecord('productdescription') + ',')
  ),
  UpdateRecord('opportunity',
          [opportunity.opportunityid],
          SetAttribute('description',Trim(GetVar('CSV List'),',') )
  ) 
) 
Setup - Quick Button
- Create the Quick Button for this formula
- Open the form designer of the Opportunity entity
- Click on the Insert tab and click on Web Resource
- In the Web Resource field that appears, seach for "north52_quick_"
- Select north52_quick_button_advanced_htm
