Drop Points will be available only if you are using Workflow 2.0.
Drop Points enable you to scan documents into electronic Drop Points for processing. Doing so will allow you to prepare documents to be scanned and processed them in bulk, to process electronically instead of manually which will increase the efficiency of the day to day task of processing documents.
For Workflow 2.0, you need to create Drop Points instead of Workflow Queues. To create Drop Points, click Drop Points option available on the toolbar as displayed in below screen.
