Affected users: users using the Return to Sender function.
Task affected: The client would like to have the document generated during the Return to Sender operation (document + Cover) to be saved automatically in the Received documents of the patient chart.
Impact: The users would like to have proof of the fax directly in the chart itself without going to the portfolio.
Current state: No alternative. The users need to search in the portfolio.
