Explanation:
Box 1: Electronic reporting
You can use Electronic reporting (ER) to format vendor checks. Many bank-specific and check provider-specific check formats are available on the market. Sample check formats have been included in the Payment check model in the ER tool repository. These sample checks are labeled Check in the middle (US) and Check on top stub below (US).
Box 2: Document management
Business document management is built on top of the ER framework and enables business users to edit business document templates by using Microsoft 365 service or appropriate Microsoft Office desktop application. Edits to the documents might include changing business document designs and adding placeholders for additional data without source code changes and new deployments. No knowledge of the ER framework is required to update templates of business documents.
