Re: How to synchronize Line Item Subset based on Line item ?
You can perform synchronization of Line Items, only if the same module is used.
If you want to perform synchronization of Line Item Subsets, i.e. through Module 2 in your example, then you'll have to either add Module 2 in the dashboard, OR you can create Module 3 using the same Line Item Subset. By clicking on a Line Item Subset member in Module 2 (along rows), the page selector in Module 3 which uses the same Line Item Subset will be synchronized.
