The number of clicks required to create a related list record against a master is tedious. It gets more complex if we require to pick and choose a number of the other parent records to create records against. somewhat like the opportunity product list where we create Opp- Products against the opportunity but by choosing the product to peg it against.
Another example of this is the "Fund Recommendations List" on Accounts or "Selected Funds" on Opportunity etc from the Arxxus Solution for Fund Managers.
Let us discuss a technique to model this scalably using VF and Apex so that we are able to filter and paginate through tons of records to create required related records easily directly off the parent record.
