Hi John,
Thank you for the questions. If the approval is required for a specific type of record and process, then each of those records will need to be approved. It is not possible to consolidate the approval of multiple records into a single step/process.
The approver can see all of the work (records) which are assigned to them by searching for and opening the Requests to Approve page within Dynamics 365 for Financials (business edition). From this page, they can Approve, Reject, or Delegate each record.
To see the history of the approvals for a given record, open that record, and then look for the Approvals button in the ribbon. Clicking on this button will open the Approval Entries page. This will show the history of the approvals for the record in question--including whether it is currently pending approval. Similarly, you can search for and open the Posted Approval Entries in order to see the similar information for historical/posted transactions.
