I would like to have the ability to attach files to lead/opportunity record in MS Dynamics 365 (CRM) and be able to validate that the files have been attached. The out-of-the-box way of attaching files seems to be using Notes.
I have a custom two-options fields on my lead entity supporting_lead_docs_attached. If a user uploads the files using Notes and sets the supporting_lead_docs_attached filed value to completed, how do i make sure that the user has actually attached a file against supporting_lead_docs_attached?
Is there a way to achieve this behavior using custom js/c# code?
